There is a misalignment between the format of the `data_files` specified in the configs metadata YAML (CSV): ```yaml configs: - config_name: default data_files: - split: train path: data.csv ``` and the inferred builder (JSON). Note there are multiple JSON files in the repo, but they do not appear in the configs metadata YAML.

[ "Hi, thanks for the suggestion. It's not possible at the moment. The viewer is part of the Hub codebase and only works on public datasets. Also, it relies on [Datasets Server](https://github.com/huggingface/datasets-server/), which prepares the data and provides an API to access the rows, size, etc.\r\n\r\nIf you're interested in hosting your data as a private dataset on the Hub, you might want to look at https://github.com/huggingface/datasets-server/issues/39.", "Hi, we are building an offline dataset viewer: https://github.com/Renumics/spotlight\r\nIt supports many HF datasets, but currently you have to use it via Pandas:\r\ndf=ds.to_pandas()\r\nspotlight.show(df)\r\n\r\nWould love to hear from you if that works for your use case. If not, feel free to open an issue on the repo: https://github.com/Renumics/spotlight/issues", "@ssuwelack thank you!

### Feature request The dataset viewer feature is very nice. It enables to the user to easily view the dataset. However, when working for private companies we cannot always upload the dataset to the hub. Is there a way to create dataset viewer offline? I.e. to run a code that will open some kind of html or something that makes it easy to view the dataset. ### Motivation I want to easily view my dataset even when it is hosted locally. ### Your contribution N.A.

### Describe the bug related issue: https://github.com/apache/arrow/issues/37057#issue-1841013613 --- Hello. I'm trying to interact with HDFS storage from a driver and workers of pyspark YARN cluster. Precisely I'm using **huggingface's `datasets`** ([link](https://github.com/huggingface/datasets)) library that relies on pyarrow to communicate with HDFS. The `from_spark()` ([link](https://huggingface.co/docs/datasets/use_with_spark#load-from-spark)) is what I'm invoking in my script. Below is the error I'm encountering. Note that I've masked sensitive paths. My code is sent to worker containers (docker) from driver container then executed. I confirmed that in both driver and worker images I can connect to HDFS using pyarrow since the envs and required jars are properly set, but strangely that becomes impossible when the same image runs as remote worker process. These are some peculiarities in my environment that might caused this issue. * **Cluster requires kerberos authentication** * But I think the error message implies that's not the problem in this case * **The user that runs the worker process is different from that built the docker image** * To avoid permission-related issues I made all directories that are accessed from the script accessible to everyone * **Pyspark-part of my code has no problem interacting with HDFS.** * Even pyarrow doesn't experience problem when I run the code in interactive session of the same docker images (driver, worker) * The problem occurs only when it runs as cluster's worker runtime Hope I could get some help. Thanks. ```bash 2023-08-08 18:51:19,638 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable 2023-08-08 18:51:20,280 WARN

### Describe the bug If one installs `apache-beam` alongside `datasets` (which is required for the [wikipedia](https://huggingface.co/datasets/wikipedia#dataset-summary) dataset) in certain environments (such as a Google Colab notebook), they appear to install successfully, however, actually trying to do something such as importing the `load_dataset` method from `datasets` results in a crashing error. I think the problem is that `apache-beam` version 2.49.0 requires `dill>=0.3.1.1,<0.3.2`, but the latest version of `multiprocess` (0.70.15) (on which `datasets` depends) requires `dill>=0.3.7,`, so this is causing the dependency resolver to use an older version of `multiprocess` which leads to the `datasets` crashing since it doesn't actually appear to be compatible with older versions. ### Steps to reproduce the bug See this [Google Colab notebook](https://colab.research.google.com/drive/1PTeGlshamFcJZix_GiS3vMXX_YzAhGv0?usp=sharing) to easily reproduce the bug. In some environments, I have been able to reproduce the bug by running the following in Bash: ```bash $ pip install datasets apache-beam ``` then the following in a Python shell: ```python from datasets import load_dataset ``` Here is my stacktrace from running on Google Colab: <details> <summary>stacktrace</summary> ``` [/usr/local/lib/python3.10/dist-packages/datasets/__init__.py](https://localhost:8080/#) in <module> 20 __version__ = "2.14.4" 21 ---> 22 from .arrow_dataset import Dataset 23 from .arrow_reader import ReadInstruction 24 from .builder import ArrowBasedBuilder, BeamBasedBuilder, BuilderConfig, DatasetBuilder, GeneratorBasedBuilder [/usr/local/lib/python3.10/dist-packages/datasets/arrow_dataset.py](https://localhost:8080/#) in <module> 64 65 from . import config ---> 66 from .arrow_reader import ArrowReader 67 from .arrow_writer import ArrowWriter, OptimizedTypedSequence 68 from .data_files import sanitize_patterns [/usr/local/lib/python3.10/dist-packages/datasets/arrow_reader.py](https://localhost:8080/#) in <module> 28 import pyarrow.parquet as pq 29 ---> 30 from .download.download_config import DownloadConfig 31 from .naming import _split_re, filenames_for_dataset_split 32 from .table import InMemoryTable, MemoryMappedTable, Table, concat_tables [/usr/local/lib/python3.10/dist-packages/datasets/download/__init__.py](https://localhost:8080/#) in <module> 7 8 from .download_config import DownloadConfig ----> 9 from .download_manager import DownloadManager, DownloadMode 10 from .streaming_download_manager import StreamingDownloadManager [/usr/local/lib/python3.10/dist-packages/datasets/download/download_manager.py](https://localhost:8080/#) in <module> 33 from ..utils.info_utils import get_size_checksum_dict 34 from ..utils.logging import get_logger, is_progress_bar_enabled, tqdm ---> 35 from ..utils.py_utils import NestedDataStructure, map_nested, size_str 36 from .download_config import DownloadConfig 37 [/usr/local/lib/python3.10/dist-packages/datasets/utils/py_utils.py](https://localhost:8080/#) in <module> 38 import dill 39 import multiprocess ---> 40 import multiprocess.pool 41 import numpy as np 42 from packaging import version [/usr/local/lib/python3.10/dist-packages/multiprocess/pool.py](https://localhost:8080/#) in <module> 607 # 608 --> 609 class ThreadPool(Pool): 610 611 from .dummy import Process [/usr/local/lib/python3.10/dist-packages/multiprocess/pool.py](https://localhost:8080/#) in ThreadPool() 609 class ThreadPool(Pool): 610 --> 611 from .dummy import Process 612 613 def __init__(self, processes=None, initializer=None, initargs=()): [/usr/local/lib/python3.10/dist-packages/multiprocess/dummy/__init__.py](https://localhost:8080/#) in <module> 85 # 86 ---> 87 class Condition(threading._Condition): 88 # XXX 89 if sys.version_info < (3, 0): AttributeError: module 'threading' has no attribute '_Condition' ``` </details> I've also found that attempting to install these `datasets` and `apache-beam` in certain environments (e.g. via pip inside a conda env) simply causes pip to hang indefinitely. ### Expected behavior I would expect to be able to import methods from `datasets` without crashing. I have tested that this is possible as long as I do not attempt to install `apache-beam`. ### Environment info Google Colab

### Describe the bug https://github.com/huggingface/datasets/blob/12cfc1196e62847e2e8239fbd727a02cbc86ddec/src/datasets/builder.py#L518-L522 If `config_name` is `None`, `DEFAULT_CONFIG_NAME` should be select. But once users pass `config_kwargs` to their customized `BuilderConfig`, the logic is ignored, and dataset cannot select the default config from multiple configs. ### Steps to reproduce the bug ```python import datasets datasets.load_dataset('/dataset/with/multiple/config'') # Ok datasets.load_dataset('/dataset/with/multiple/config', some_field_in_config='some') # Err ``` ### Expected behavior Default config behavior should be consistent. ### Environment info - `datasets` version: 2.14.3 - Platform: Linux-5.15.0-76-generic-x86_64-with-glibc2.17 - Python version: 3.8.15 - Huggingface_hub version: 0.16.4 - PyArrow version: 12.0.1 - Pandas version: 1.5.3

### Describe the bug Since the release of `datasets` 2.14, private/gated datasets do not load when passing `token`: they raise `EmptyDatasetError`. This is a non-planned backward incompatible breaking change. Note that private datasets do load if instead `download_config` is passed: ```python from datasets import DownloadConfig, load_dataset ds = load_dataset("albertvillanova/tmp-private", split="train", download_config=DownloadConfig(token="<MY-TOKEN>")) ds ``` gives ``` Dataset({ features: ['text'], num_rows: 4 }) ``` ### Steps to reproduce the bug ```python from datasets import load_dataset ds = load_dataset("albertvillanova/tmp-private", split="train", token="<MY-TOKEN>") ``` gives ``` --------------------------------------------------------------------------- EmptyDatasetError Traceback (most recent call last) [<ipython-input-2-25b48732107a>](https://localhost:8080/#) in <cell line: 3>() 1 from datasets import load_dataset 2 ----> 3 ds = load_dataset("albertvillanova/tmp-private", split="train", token="<MY-TOKEN>") 5 frames [/usr/local/lib/python3.10/dist-packages/datasets/load.py](https://localhost:8080/#) in load_dataset(path, name, data_dir, data_files, split, cache_dir, features, download_config, download_mode, verification_mode, ignore_verifications, keep_in_memory, save_infos, revision, token, use_auth_token, task, streaming, num_proc, storage_options, **config_kwargs) 2107 2108 # Create a dataset builder -> 2109 builder_instance = load_dataset_builder( 2110 path=path, 2111 name=name, [/usr/local/lib/python3.10/dist-packages/datasets/load.py](https://localhost:8080/#) in load_dataset_builder(path, name, data_dir, data_files, cache_dir, features, download_config, download_mode, revision, token, use_auth_token, storage_options, **config_kwargs) 1793 download_config = download_config.copy() if download_config else DownloadConfig() 1794 download_config.storage_options.update(storage_options) -> 1795 dataset_module = dataset_module_factory( 1796 path, 1797 revision=revision, [/usr/local/lib/python3.10/dist-packages/datasets/load.py](https://localhost:8080/#) in dataset_module_factory(path, revision, download_config, download_mode, dynamic_modules_path, data_dir, data_files, **download_kwargs) 1484 raise ConnectionError(f"Couldn't reach the Hugging Face Hub for dataset '{path}': {e1}") from None 1485 if isinstance(e1, EmptyDatasetError): -> 1486 raise e1 from None 1487 if isinstance(e1, FileNotFoundError): 1488 raise FileNotFoundError( [/usr/local/lib/python3.10/dist-packages/datasets/load.py](https://localhost:8080/#) in dataset_module_factory(path, revision, download_config, download_mode, dynamic_modules_path, data_dir, data_files, **download_kwargs) 1474 download_config=download_config, 1475 download_mode=download_mode, -> 1476 ).get_module() 1477 except ( 1478 Exception [/usr/local/lib/python3.10/dist-packages/datasets/load.py](https://localhost:8080/#) in get_module(self) 1030 sanitize_patterns(self.data_files) 1031 if self.data_files is not None -> 1032 else get_data_patterns(base_path, download_config=self.download_config) 1033 ) 1034 data_files = DataFilesDict.from_patterns( [/usr/local/lib/python3.10/dist-packages/datasets/data_files.py](https://localhost:8080/#) in get_data_patterns(base_path, download_config) 457 return _get_data_files_patterns(resolver) 458 except FileNotFoundError: --> 459 raise EmptyDatasetError(f"The directory at {base_path} doesn't contain any data files") from None 460 461 EmptyDatasetError: The directory at hf://datasets/albertvillanova/tmp-private@79b9e4fe79670a9a050d6ebc385464891915a71d doesn't contain any data files ``` ### Expected behavior The dataset should load. ### Environment info - `datasets` version: 2.14.3 - Platform: Linux-5.15.109+-x86_64-with-glibc2.35 - Python version: 3.10.12 - Huggingface_hub version: 0.16.4 - PyArrow version: 9.0.0 - Pandas version: 1.5.3

### Describe the bug In https://huggingface.co/models there are task categories for RL and robotics but none in https://huggingface.co/datasets Our lab is currently moving our datasets over to hugging face and would like to be able to add those 2 tags Moreover we see some older datasets that do have that tag, but we can't seem to add it ourselves. ### Steps to reproduce the bug 1. Create a new dataset on Hugging face 2. Try to type reinforcemement-learning or robotics into the tasks categories, it does not allow you to commit ### Expected behavior Expected to be able to add RL and robotics as task categories as some previous datasets have these tags ### Environment info N/A

### Describe the bug I would like to bring to your attention an issue related to the accuracy of bounding boxes within the "wildreceipt" dataset, which is made available through the Hugging Face API. Specifically, I have identified a discrepancy between the bounding boxes generated by the dataset loading commands, namely `load_dataset("Theivaprakasham/wildreceipt")` and `load_dataset("jinhybr/WildReceipt")`, and the actual labels and corresponding bounding boxes present in the dataset. To illustrate this divergence, I've provided two examples in the form of screenshots. These screenshots highlight the contrasting outcomes between my personal implementation of the dataloader and the implementation offered by Hugging Face: **Example 1:** ![image](https://github.com/huggingface/datasets/assets/50714796/7a6604d2-899d-4102-a008-1a28c90698f1) ![image](https://github.com/huggingface/datasets/assets/50714796/eba458c7-d3af-4868-a520-8b683aa96f66) ![image](https://github.com/huggingface/datasets/assets/50714796/9f394891-5f5b-46f7-8e52-071b724aedab) **Example 2:** ![image](https://github.com/huggingface/datasets/assets/50714796/a2b2a8d3-124e-4990-b64a-5133cf4be2fe) ![image](https://github.com/huggingface/datasets/assets/50714796/6ee25642-35aa-40ad-ac1e-899d33be90df) ![image](https://github.com/huggingface/datasets/assets/50714796/5e42ff91-9fc4-4520-8803-0e225656f96c) It's important to note that my dataloader implementation is based on the same dataset files as utilized in the Hugging Face implementation. For your reference, you can access the dataset files through this link: [wildreceipt dataset files](https://download.openmmlab.com/mmocr/data/wildreceipt.tar). This inconsistency in bounding box accuracy warrants investigation and rectification for maintaining the integrity of the "wildreceipt" dataset. Your attention and assistance in addressing this matter would be greatly appreciated. ### Steps to reproduce the bug ```python import matplotlib.pyplot as plt from datasets import load_dataset # Define functions to convert bounding box formats def convert_format1(box): x, y, w, h = box x2, y2 = x + w, y + h return [x, y, x2, y2] def convert_format2(box): x1, y1, x2, y2 = box return [x1, y1, x2, y2] def plot_cropped_image(image, box, title): cropped_image = image.crop(box) plt.imshow(cropped_image) plt.title(title) plt.axis('off') plt.savefig(title+'.png') plt.show() doc_index = 1 word_index = 3 dataset = load_dataset("Theivaprakasham/wildreceipt")['train'] bbox_hugging_face = dataset[doc_index]['bboxes'][word_index] text_unit_face = dataset[doc_index]['words'][word_index] common_box_hugface_1 = convert_format1(bbox_hugging_face) common_box_hugface_2 = convert_format2(bbox_hugging_face) plot_cropped_image(image_hugging, common_box_hugface_1, f'Hugging Face Bouding boxes (x,y,w,h format) \n its associated text unit: {text_unit_face}') plot_cropped_image(image_hugging, common_box_hugface_2, f'Hugging Face Bouding boxes (x1,y1,x2, y2 format) \n its associated text unit: {text_unit_face}') ``` ### Expected behavior The bounding boxes generated by the "wildreceipt" dataset in HuggingFace implementation loading commands should accurately match the actual labels and bounding boxes of the dataset. ### Environment info - Python version: 3.8 - Hugging Face datasets version: 2.14.2 - Dataset file taken from this link: https://download.openmmlab.com/mmocr/data/wildreceipt.tar

### Feature request `push_to_hub` now allows users to upload datasets programmatically. However, based on the latest doc, we still need to open the dataset page to add readme file manually. However, I do discover snippets to intialize a README for every `push_to_hub`: ``` dataset_card = ( DatasetCard( "---\n" + str(dataset_card_data) + "\n---\n" + f'# Dataset Card for "{repo_id.split("/")[-1]}"\n\n[More Information needed](https://github.com/huggingface/datasets/blob/main/CONTRIBUTING.md#how-to-contribute-to-the-dataset-cards)' ) if dataset_card is None else dataset_card ) HfApi(endpoint=config.HF_ENDPOINT).upload_file( path_or_fileobj=str(dataset_card).encode(), path_in_repo="README.md", repo_id=repo_id, token=token, repo_type="dataset", revision=branch, ) ``` So, if we can enable `push_to_hub` to upload a readme file by ourselves instead of using the auto generated ones, it can save ton of time, and will definitely alleviate the current "lack-of-dataset-card" situation. ### Motivation as elabrated above. ### Your contribution I might be able to make a pr.

### Feature request From what I understand, streaming dataset currently pulls the data, and process the data as it is requested. This can introduce significant latency delays when data is loaded into the training process, needing to wait for each segment. While the delays might be dataset specific (or even mapping instruction/tokenizer specific) Is it possible to introduce a `streaming_lookahead` parameter, which is used for predictable workloads (even shuffled dataset with fixed seed). As we can predict in advance what the next few datasamples will be. And fetch them while the current set is being trained. With enough CPU & bandwidth to keep up with the training process, and a sufficiently large lookahead, this will reduce the various latency involved while waiting for the dataset to be ready between batches. ### Motivation Faster streaming performance, while training over extra large TB sized datasets ### Your contribution I currently use HF dataset, with pytorch lightning trainer for RWKV project, and would be able to help test this feature if supported.

### Describe the bug **Description** Providing a generator in an instantiation of IterableDataset.from_generator() fails with `TypeError: cannot pickle 'generator' object` when the generator argument is supplied with a generator. **Code example** ``` def line_generator(files: List[Path]): if isinstance(files, str): files = [Path(files)] for file in files: if isinstance(file, str): file = Path(file) yield from open(file,'r').readlines() ... model_training_files = ['file1.txt', 'file2.txt', 'file3.txt'] train_dataset = IterableDataset.from_generator(generator=line_generator(model_training_files)) ``` **Traceback** Traceback (most recent call last): File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/contextlib.py", line 135, in __exit__ self.gen.throw(type, value, traceback) File "/Users/d3p692/code/clem_bert/venv/lib/python3.9/site-packages/datasets/utils/py_utils.py", line 691, in _no_cache_fields yield File "/Users/d3p692/code/clem_bert/venv/lib/python3.9/site-packages/datasets/utils/py_utils.py", line 701, in dumps dump(obj, file) File "/Users/d3p692/code/clem_bert/venv/lib/python3.9/site-packages/datasets/utils/py_utils.py", line 676, in dump Pickler(file, recurse=True).dump(obj) File "/Users/d3p692/code/clem_bert/venv/lib/python3.9/site-packages/dill/_dill.py", line 394, in dump StockPickler.dump(self, obj) File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/pickle.py", line 487, in dump self.save(obj) File "/Users/d3p692/code/clem_bert/venv/lib/python3.9/site-packages/datasets/utils/py_utils.py", line 666, in save dill.Pickler.save(self, obj, save_persistent_id=save_persistent_id) File "/Users/d3p692/code/clem_bert/venv/lib/python3.9/site-packages/dill/_dill.py", line 388, in save StockPickler.save(self, obj, save_persistent_id) File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/pickle.py", line 560, in save f(self, obj) # Call unbound method with explicit self File "/Users/d3p692/code/clem_bert/venv/lib/python3.9/site-packages/dill/_dill.py", line 1186, in save_module_dict StockPickler.save_dict(pickler, obj) File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/pickle.py", line 971, in save_dict self._batch_setitems(obj.items()) File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/pickle.py", line 997, in _batch_setitems save(v) File "/Users/d3p692/code/clem_bert/venv/lib/python3.9/site-packages/datasets/utils/py_utils.py", line 666, in save dill.Pickler.save(self, obj, save_persistent_id=save_persistent_id) File "/Users/d3p692/code/clem_bert/venv/lib/python3.9/site-packages/dill/_dill.py", line 388, in save StockPickler.save(self, obj, save_persistent_id) File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/pickle.py", line 578, in save rv = reduce(self.proto) TypeError: cannot pickle 'generator' object ### Steps to reproduce the bug 1. Create a set of text files to iterate over. 2. Create a generator that returns the lines in each file until all files are exhausted. 3. Instantiate the dataset over the generator by instantiating an IterableDataset.from_generator(). 4. Wait for the explosion. ### Expected behavior I would expect that since the function claims to accept a generator that there would be no crash. Instead, I would expect the dataset to return all the lines in the files as queued up in the `line_generator()` function. ### Environment info datasets.__version__ == '2.13.1' Python 3.9.6 Platform: Darwin WE35261 22.5.0 Darwin Kernel Version 22.5.0: Thu Jun 8 22:22:22 PDT 2023; root:xnu-8796.121.3~7/RELEASE_X86_64 x86_64

### Feature request The [how to process dataset guide](https://huggingface.co/docs/datasets/main/en/process) currently does not mention the [`select_columns`](https://huggingface.co/docs/datasets/main/en/package_reference/main_classes#datasets.Dataset.select_columns) function. It would be nice to include it in the guide. ### Motivation This function is a commonly requested feature (see this [forum thread](https://discuss.huggingface.co/t/how-to-create-a-new-dataset-from-another-dataset-and-select-specific-columns-and-the-data-along-with-the-column/15120) and #5468 #5474). However, it has not been included in the guide since its implementation by PR #5480. Mentioning it in the guide would help future users discover this added feature. ### Your contribution I could submit a PR to add a brief description of the function to said guide.

### Describe the bug I have commonvoice 8.0.0 downloaded in `~/.cache/huggingface/datasets/mozilla-foundation___common_voice_8_0/en/8.0.0/b2f8b72f8f30b2e98c41ccf855954d9e35a5fa498c43332df198534ff9797a4a`. The folder contains all the arrow files etc, and was used as the cached version last time I touched the ec2 instance I'm working on. Now, with the same command that downloaded it initially: ``` dataset = load_dataset("mozilla-foundation/common_voice_8_0", "en", use_auth_token="<mytoken>") ``` it tries to redownload the dataset to `~/.cache/huggingface/datasets/mozilla-foundation___common_voice_8_0/en/8.0.0/05bdc7940b0a336ceeaeef13470c89522c29a8e4494cbeece64fb472a87acb32` ### Steps to reproduce the bug Steps to reproduce the behavior: 1. ```dataset = load_dataset("mozilla-foundation/common_voice_8_0", "en", use_auth_token="<mytoken>")``` 2. dataset is updated by maintainers 3. ```dataset = load_dataset("mozilla-foundation/common_voice_8_0", "en", use_auth_token="<mytoken>")``` ### Expected behavior I expect that it uses the already downloaded data in `~/.cache/huggingface/datasets/mozilla-foundation___common_voice_8_0/en/8.0.0/b2f8b72f8f30b2e98c41ccf855954d9e35a5fa498c43332df198534ff9797a4a`. Not sure what's happening in 2. but if, say it's an issue with the dataset referenced by "mozilla-foundation/common_voice_8_0" being modified by the maintainers, how would I force datasets to point to the original version I downloaded? EDIT: It was indeed that the maintainers had updated the dataset (v 8.0.0). However I still cant load the dataset from disk instead of redownloading, with for example: ``` load_dataset(".cache/huggingface/datasets/downloads/extracted/<hash>/cv-corpus-8.0-2022-01-19/en/", "en") > ... > File [~/miniconda3/envs/aa_torch2/lib/python3.10/site-packages/datasets/table.py:1938](.../ python3.10/site-packages/datasets/table.py:1938), in cast_array_to_feature(array, feature, allow_number_to_str) 1937 elif not isinstance(feature, (Sequence, dict, list, tuple)): -> 1938 return array_cast(array, feature(), allow_number_to_str=allow_number_to_str) ... 1794 e = e.__context__ -> 1795 raise DatasetGenerationError("An error occurred while generating the dataset") from e 1797 yield job_id, True, (total_num_examples, total_num_bytes, writer._features, num_shards, shard_lengths) DatasetGenerationError: An error occurred while generating the dataset ``` ### Environment info datasets==2.7.0 python==3.10.8 OS: AWS Linux

### Describe the bug For researchers in some countries or regions, it is usually the case that the download ability of `load_dataset` is disabled due to the complex network environment. People in these regions often prefer to use git clone or other programming tricks to manually download the files to the disk (for example, [How to elegantly download hf models, zhihu zhuanlan](https://zhuanlan.zhihu.com/p/475260268) proposed a crawlder based solution, and [Is there any mirror for hf_hub, zhihu answer](https://www.zhihu.com/question/371644077) provided some cloud based solutions, and [How to avoid pitfalls on Hugging face downloading, zhihu zhuanlan] gave some useful suggestions), and then use `load_from_disk` to get the dataset object. However, when one finally has the local files on the disk, it is still buggy when trying to load the files into objects. ### Steps to reproduce the bug Steps to reproduce the bug: 1. Found CIFAR dataset in hugging face: https://huggingface.co/datasets/cifar100/tree/main 2. Click ":" button to show "Clone repository" option, and then follow the prompts on the box: ```bash cd my_directory_absolute git lfs install git clone https://huggingface.co/datasets/cifar100 ls my_directory_absolute/cifar100 # confirm that the directory exists and it is OK. ``` 3. Write A python file to try to load the dataset ```python from datasets import load_dataset, load_from_disk dataset = load_from_disk("my_directory_absolute/cifar100") ``` Notice that according to issue #3700 , it is wrong to use load_dataset("my_directory_absolute/cifar100"), so we must use load_from_disk instead. 4. Then you will see the error reported: ```log --------------------------------------------------------------------------- FileNotFoundError Traceback (most recent call last) Cell In[5], line 9 1 from datasets import load_dataset, load_from_disk ----> 9 dataset = load_from_disk("my_directory_absolute/cifar100") File [~/miniconda3/envs/ai/lib/python3.10/site-packages/datasets/load.py:2232), in load_from_disk(dataset_path, fs, keep_in_memory, storage_options) 2230 return DatasetDict.load_from_disk(dataset_path, keep_in_memory=keep_in_memory, storage_options=storage_options) 2231 else: -> 2232 raise FileNotFoundError( 2233 f"Directory {dataset_path} is neither a `Dataset` directory nor a `DatasetDict` directory." 2234 ) FileNotFoundError: Directory my_directory_absolute/cifar100 is neither a `Dataset` directory nor a `DatasetDict` directory. ``` ### Expected behavior The dataset should be load successfully. ### Environment info ```bash datasets-cli env ``` -> results: ```txt Copy-and-paste the text below in your GitHub issue. - `datasets` version: 2.14.2 - Platform: Linux-4.18.0-372.32.1.el8_6.x86_64-x86_64-with-glibc2.28 - Python version: 3.10.12 - Huggingface_hub version: 0.16.4 - PyArrow version: 12.0.1 - Pandas version: 2.0.3 ```

### Describe the bug `Dataset` initialized from in-memory data (dictionary in my case, haven't tested with other types) does not create cache when processed with the `map` method, unlike `Dataset` initialized by other methods such as `load_dataset`. ### Steps to reproduce the bug ```python # below code was run the second time so the map function can be loaded from cache if exists from datasets import load_dataset, Dataset dataset = load_dataset("tatsu-lab/alpaca")['train'] dataset = dataset.map(lambda x: {'input': x['input'] + 'hi'}) # some random map print(len(dataset.cache_files)) # 1 # copy the exact same data but initialize from a dictionary memory_dataset = Dataset.from_dict({ 'instruction': dataset['instruction'], 'input': dataset['input'], 'output': dataset['output'], 'text': dataset['text']}) memory_dataset = memory_dataset.map(lambda x: {'input': x['input'] + 'hi'}) # exact same map print(len(memory_dataset.cache_files)) # Map: 100%|██████████| 52002[/52002] # 0 ``` ### Expected behavior The `map` function should create cache regardless of the method the `Dataset` was created. ### Environment info - `datasets` version: 2.14.2 - Platform: Linux-5.15.0-41-generic-x86_64-with-glibc2.31 - Python version: 3.9.16 - Huggingface_hub version: 0.14.1 - PyArrow version: 11.0.0 - Pandas version: 1.5.3

Finally I found the problem seems to be with `pyarrow`'s json parser, and it seems a long-existing problem. Similar issue can be found in #2181. Anyway, my solution is to adjust the `load_dataset`'s parameter `chunksize`. You can inspect the parameter set in `datasets/packaged_modules/json/json.py`, now the actual chunksize should be very small, and you can increase the value. For me, `chunksize=10<<23` could solve the stuck problem. But I also find that too big `chunksize`, like `10 << 30`, would also cause a stuck, which is rather weird.

### Describe the bug I try to use `load_dataset()` to load several local `.jsonl` files as a dataset. Every line of these files is a json structure only containing one key `text` (yeah it is a dataset for NLP model). The code snippet is as: ```python ds = load_dataset("json", data_files=LIST_OF_FILE_PATHS, num_proc=16)['train'] ``` However, I found that the loading process can get stuck -- the progress bar `Generating train split` no more proceed. When I was trying to find the cause and solution, I found a really strange behavior. If I load the dataset in this way: ```python dlist = list() for _ in LIST_OF_FILE_PATHS: dlist.append(load_dataset("json", data_files=_)['train']) ds = concatenate_datasets(dlist) ``` I can actually successfully load all the files despite its slow speed. But if I load them in batch like above, things go wrong. I did try to use Control-C to trace the stuck point but the program cannot be terminated in this way when `num_proc` is set to `None`. The only thing I can do is use Control-Z to hang it up then kill it. If I use more than 2 cpus, a Control-C would simply cause the following error: ```bash ^C Process ForkPoolWorker-1: Traceback (most recent call last): File "/usr/local/lib/python3.10/dist-packages/multiprocess/process.py", line 314, in _bootstrap self.run() File "/usr/local/lib/python3.10/dist-packages/multiprocess/process.py", line 108, in run self._target(*self._args, **self._kwargs) File "/usr/local/lib/python3.10/dist-packages/multiprocess/pool.py", line 114, in worker task = get() File "/usr/local/lib/python3.10/dist-packages/multiprocess/queues.py", line 368, in get res = self._reader.recv_bytes() File "/usr/local/lib/python3.10/dist-packages/multiprocess/connection.py", line 224, in recv_bytes buf = self._recv_bytes(maxlength) File "/usr/local/lib/python3.10/dist-packages/multiprocess/connection.py", line 422, in _recv_bytes buf = self._recv(4) File "/usr/local/lib/python3.10/dist-packages/multiprocess/connection.py", line 387, in _recv chunk = read(handle, remaining) KeyboardInterrupt Generating train split: 92431 examples [01:23, 1104.25 examples/s] Traceback (most recent call last): File "/usr/local/lib/python3.10/dist-packages/datasets/utils/py_utils.py", line 1373, in iflatmap_unordered yield queue.get(timeout=0.05) File "<string>", line 2, in get File "/usr/local/lib/python3.10/dist-packages/multiprocess/managers.py", line 818, in _callmethod kind, result = conn.recv() File "/usr/local/lib/python3.10/dist-packages/multiprocess/connection.py", line 258, in recv buf = self._recv_bytes() File "/usr/local/lib/python3.10/dist-packages/multiprocess/connection.py", line 422, in _recv_bytes buf = self._recv(4) File "/usr/local/lib/python3.10/dist-packages/multiprocess/connection.py", line 387, in _recv chunk = read(handle, remaining) KeyboardInterrupt During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/mnt/data/liyongyuan/source/batch_load.py", line 11, in <module> a = load_dataset( File "/usr/local/lib/python3.10/dist-packages/datasets/load.py", line 2133, in load_dataset builder_instance.download_and_prepare( File "/usr/local/lib/python3.10/dist-packages/datasets/builder.py", line 954, in download_and_prepare self._download_and_prepare( File "/usr/local/lib/python3.10/dist-packages/datasets/builder.py", line 1049, in _download_and_prepare self._prepare_split(split_generator, **prepare_split_kwargs) File "/usr/local/lib/python3.10/dist-packages/datasets/builder.py", line 1842, in _prepare_split for job_id, done, content in iflatmap_unordered( File "/usr/local/lib/python3.10/dist-packages/datasets/utils/py_utils.py", line 1387, in iflatmap_unordered [async_result.get(timeout=0.05) for async_result in async_results] File "/usr/local/lib/python3.10/dist-packages/datasets/utils/py_utils.py", line 1387, in <listcomp> [async_result.get(timeout=0.05) for async_result in async_results] File "/usr/local/lib/python3.10/dist-packages/multiprocess/pool.py", line 770, in get raise TimeoutError multiprocess.context.TimeoutError ``` I have validated the basic correctness of these `.jsonl` files. They are correctly formatted (or they cannot be loaded singly by `load_dataset`) though some of the json may contain too long text (more than 1e7 characters). I do not know if this could be the problem. And there should not be any bottleneck in system's resource. The whole dataset is ~300GB, and I am using a cloud server with plenty of storage and 1TB ram. Thanks for your efforts and patience! Any suggestion or help would be appreciated. ### Steps to reproduce the bug 1. use load_dataset() with `data_files = LIST_OF_FILES` ### Expected behavior All the files should be smoothly loaded. ### Environment info - Datasets: A private dataset. ~2500 `.jsonl` files. ~300GB in total. Each json structure only contains one key: `text`.

### Describe the bug I tried to load local json file as dataset but failed to parsing json file because some columns are 'float' type. ### Steps to reproduce the bug 1. load json file with certain columns are 'float' type. For example `data = load_data("json", data_files=JSON_PATH)` 2. Then, the error will be triggered like `ArrowInvalid: Could not convert '-0.2253' with type str: tried to convert to double ### Expected behavior Should allow some columns are 'float' type, at least it should convert those columns to str type. I tried to avoid the error by naively convert the float item to str: ```python # if col type is not str, we need to convert it to str mapping = {} for col in keys: if isinstance(dataset[0][col], str): mapping[col] = [row.get(col) for row in dataset] else: mapping[col] = [str(row.get(col)) for row in dataset] ``` ### Environment info - `datasets` version: 2.14.2 - Platform: Linux-5.4.0-52-generic-x86_64-with-glibc2.31 - Python version: 3.9.16 - Huggingface_hub version: 0.16.4 - PyArrow version: 12.0.0 - Pandas version: 2.0.1

Profiling it: <img width="1280" alt="image" src="https://github.com/huggingface/datasets/assets/36224762/e641fb95-ff02-4072-9016-5416a65f75ab"> `some_dataset` is completely in memory with no disk cache. This is proving fatal to my usage of HF Datasets. Is there a way I can forgo the arrow format and store the dataset as PyTorch tensors so that `_tensorize` is not needed? And is `_consolidate` supposed to take this long? It's faster to produce the dataset from scratch than to access it from HF Datasets! ### Steps to reproduce the bug I have uploaded the dataset that causes this problem [here](https://huggingface.co/datasets/NightMachinery/hf_datasets_bug1). ```python #!/usr/bin/env python3 import sys import time import torch from datasets import load_dataset def main(dataset_name): # Start the timer start_time = time.time() # Load the dataset from Hugging Face Hub dataset = load_dataset(dataset_name) # Set the dataset format as torch dataset.set_format(type="torch") # Perform an identity map dataset = dataset.map(lambda example: example, batched=True, batch_size=20) # End the timer end_time = time.time() # Print the time taken print(f"Time taken: {end_time - start_time:.2f} seconds") if __name__ == "__main__": dataset_name = "NightMachinery/hf_datasets_bug1" print(f"dataset_name: {dataset_name}") main(dataset_name) ``` ### Expected behavior _ ### Environment info - `datasets` version: 2.13.1 - Platform: Linux-5.15.0-76-generic-x86_64-with-glibc2.35 - Python version: 3.10.12 - Huggingface_hub version: 0.16.4 - PyArrow version: 12.0.1 - Pandas version: 2.0.3

### Describe the bug Loading a dataset from a GCP bucket raises a type error. This bug was introduced recently (either in 2.14 or 2.14.1), and appeared during a migration from 2.13.1. ### Steps to reproduce the bug Load any file from a GCP bucket: ```python import datasets datasets.load_dataset("json", data_files=["gs://..."]) ``` The following exception is raised: ```python Traceback (most recent call last): ... packages/datasets/data_files.py", line 335, in resolve_pattern protocol_prefix = fs.protocol + "://" if fs.protocol != "file" else "" TypeError: can only concatenate tuple (not "str") to tuple ``` With a `GoogleFileSystem`, the attribute `fs.protocol` is a tuple `('gs', 'gcs')` and hence cannot be concatenated with a string. ### Expected behavior The file should be loaded without exception. ### Environment info - `datasets` version: 2.14.1 - Platform: macOS-13.2.1-x86_64-i386-64bit - Python version: 3.10.12 - Huggingface_hub version: 0.16.4 - PyArrow version: 12.0.1 - Pandas version: 2.0.3

### Describe the bug Hi team! I observe that there seems to be a side effect of `Dataset.set_format`: after setting a format and creating a FAISS index, the method `get_nearest_examples` from the `Dataset` class, fails to retrieve anything else but the embeddings themselves - not super useful. This is not the case if not using the `set_format` method: you can also retrieve any other feature value, such as an index/id/etc. Are you able to reproduce what I observe? ### Steps to reproduce the bug ```python from datasets import Dataset import numpy as np foo = {'vectors': np.random.random((100,1024)), 'ids': [str(u) for u in range(100)]} foo = Dataset.from_dict(foo) foo.set_format('numpy', ['vectors']) foo.add_faiss_index('vectors') new_vector = np.random.random(1024) scores, res = foo.get_nearest_examples('vectors', new_vector, k=3) ``` This will return, for the resulting most similar vectors to `new_vector` - in particular it will not return the `ids` feature: ``` {'vectors': array([[random values ...]])} ``` ### Expected behavior The expected behavior happens when the `set_format` method is not called: ```python from datasets import Dataset import numpy as np foo = {'vectors': np.random.random((100,1024)), 'ids': [str(u) for u in range(100)]} foo = Dataset.from_dict(foo) # foo.set_format('numpy', ['vectors']) foo.add_faiss_index('vectors') new_vector = np.random.random(1024) scores, res = foo.get_nearest_examples('vectors', new_vector, k=3) ``` This *will* return the `ids` of the similar vectors - with unfortunately a list of lists in lieu of the array I think for caching reasons - read it elsewhere ``` {'vectors': [[random values on multiple lines...]], 'ids': ['x', 'y', 'z']} ``` ### Environment info - `datasets` version: 2.12.0 - Platform: Linux-5.4.0-155-generic-x86_64-with-glibc2.31 - Python version: 3.10.6 - Huggingface_hub version: 0.15.1 - PyArrow version: 11.0.0 - Pandas version: 1.5.3

### Describe the bug When initializing `FilesIterable` with a list of file paths using `FilesIterable.from_paths`, it will discard all the files after a hidden file. The problem is in [this line](https://github.com/huggingface/datasets/blob/88896a7b28610ace95e444b94f9a4bc332cc1ee3/src/datasets/download/download_manager.py#L233C26-L233C26) where `return` should be replaced by `continue`. ### Steps to reproduce the bug https://colab.research.google.com/drive/1SQlxs4y_LSo1Q89KnFoYDSyyKEISun_J#scrollTo=93K4_blkW-8- ### Expected behavior The script should print all the files except the hidden one. ### Environment info - `datasets` version: 2.14.1 - Platform: Linux-5.15.109+-x86_64-with-glibc2.35 - Python version: 3.10.6 - Huggingface_hub version: 0.16.4 - PyArrow version: 9.0.0 - Pandas version: 1.5.3

As documented in the [official docs](https://huggingface.co/docs/datasets/v2.14.0/en/package_reference/loading_methods#datasets.load_dataset.example-2), I tried to load datasets from local files by ```python # Load a JSON file from datasets import load_dataset ds = load_dataset('json', data_files='path/to/local/my_dataset.json') ``` But this failed on a web request because I'm executing the script on a machine without Internet access. Stacktrace shows ``` in PackagedDatasetModuleFactory.__init__(self, name, data_dir, data_files, download_config, download_mode) 940 self.download_config = download_config 941 self.download_mode = download_mode --> 942 increase_load_count(name, resource_type="dataset") ``` I've read from the source code that this can be fixed by setting environment variable to run in offline mode. I'm just wondering that is this an expected behaviour that even loading a LOCAL JSON file requires Internet access by default? And what's the point of requesting to `increase_load_count` on some server when loading just LOCAL data files?

### Describe the bug fsspec.callbacks.TqdmCallback (used in https://github.com/huggingface/datasets/blob/73bed12ecda17d1573fd3bf73ed5db24d3622f86/src/datasets/utils/file_utils.py#L338) was first released in fsspec [2022.3.0](https://github.com/fsspec/filesystem_spec/releases/tag/2022.3.0, commit where it was added: https://github.com/fsspec/filesystem_spec/commit/9577c8a482eb0a69092913b81580942a68d66a76#diff-906155c7e926a9ff58b9f23369bb513b09b445f5b0f41fa2a84015d0b471c68cR180), however the dependency is set to 2021.11.1 https://github.com/huggingface/datasets/blob/main/setup.py#L129 ### Steps to reproduce the bug 1. Install fsspec==2021.11.1 2. Install latest datasets==2.14.1 3. Import datasets, import fails due to lack of `fsspec.callbacks.TqdmCallback` ### Expected behavior No import issue ### Environment info N/A

Supporting this should be fairly easy. Requested on the forum [here](https://discuss.huggingface.co/t/how-can-i-convert-a-loaded-dataset-in-to-a-parquet-file-and-save-it-to-the-s3/48353).

Hi, as I followed the instructions, with lasted "datasets" version: " from datasets import load_dataset examples = load_dataset('facebook/winoground', use_auth_token=<YOUR USER ACCESS TOKEN>) " I got slightly different datasets in colab and in my hpc environment. Specifically, the pixel values of images are slightly different. I thought it was due to the package version difference, but today's morning I found out that my winoground dataset in colab became the same with the one in my hpc environment. The dataset in colab can produce the correct result but now it is gone as well. Can you help me with this? What causes the datasets to have the wrong pixel values?

### Describe the bug I am using Amazon Sagemaker notebook (Amazon Linux 2) with python 3.10 based Conda environment. I have a dataset in parquet format locally. When I try to iterate over it, the loader is stuck forever. Note that the same code is working for python 3.6 based conda environment seamlessly. What should be my next steps here? ### Steps to reproduce the bug ``` train_dataset = load_dataset( "parquet", data_files = {'train': tr_data_path + '*.parquet'}, split = 'train', collate_fn = streaming_data_collate_fn, streaming = True ).with_format('torch') train_dataloader = DataLoader(train_dataset, batch_size = 2, num_workers = 0) t = time.time() iter_ = 0 for batch in train_dataloader: iter_ += 1 if iter_ == 1000: break print (time.time() - t) ``` ### Expected behavior The snippet should work normally and load the next batch of data. ### Environment info datasets: '2.14.0' pyarrow: '12.0.0' torch: '2.0.0' Python: 3.10.10 | packaged by conda-forge | (main, Mar 24 2023, 20:08:06) [GCC 11.3.0] !uname -r 5.10.178-162.673.amzn2.x86_64

### Describe the bug I used: ``` dataset = load_dataset( "oscar-corpus/OSCAR-2201", token=True, language="fr", streaming=True, split="train" ) ``` Unfortunately, the server had a problem during the training process. I saved the step my training stopped at. But how can I resume download from step 1_000_´000 without re-streaming all the first 1 million docs of the dataset? `download_config=DownloadConfig(resume_download=True)` seems to not work with streaming=True. ### Steps to reproduce the bug ``` from datasets import load_dataset, DownloadConfig dataset = load_dataset( "oscar-corpus/OSCAR-2201", token=True, language="fr", streaming=True, # optional split="train", download_config=DownloadConfig(resume_download=True) ) # interupt the run and try to relaunch it => this restart from scratch ``` ### Expected behavior I would expect a parameter to start streaming from a given index in the dataset. ### Environment info - `datasets` version: 2.14.0 - Platform: Linux-5.19.0-45-generic-x86_64-with-glibc2.29 - Python version: 3.8.10 - Huggingface_hub version: 0.15.1 - PyArrow version: 12.0.1 - Pandas version: 2.0.0

[ "The `MAX_MAP_BATCH_SIZE = 1_000_000_000` hack is bad as it loads the entire dataset into RAM when performing `.map`. Instead, it's best to use `.iter(batch_size)` to iterate over the data batches and compute `mean` for each column. (`stddev` can be computed in another pass).\r\n\r\nAlso, these arrays are big, so it makes sense to reduce `batch_size`/`writer_batch_size` to avoid RAM issues and slow IO.", "Hi @mariosasko !\r\n\r\nI agree, it's an ugly hack, but it was convenient since the resulting `mean_std` could be cached by the library. For my large dataset (which doesn't fit in RAM), I'm actually using something similar to what you suggested. I got rid of the first mapping in the above scripts and replaced it with an iterator, but the issue with the second mapping still persists.", "Have you tried to reduce `batch_size`/`writer_batch_size` in the 2nd `.map`? Also, can you interrupt the process when it gets stuck and share the error stack trace?", "I think `batch_size/writer_batch_size` is already at its lowest in the 2nd `.map` since `batched=False`

### Describe the bug Hi ! I'm currently working with a large (~150GB) unnormalized dataset at work. The dataset is available on a read-only filesystem internally, and I use a [loading script](https://huggingface.co/docs/datasets/dataset_script) to retreive it. I want to normalize the features of the dataset, meaning I need to compute the mean and standard deviation metric for each feature of the entire dataset. I cannot load the entire dataset to RAM as it is too big, so following [this discussion on the huggingface discourse](https://discuss.huggingface.co/t/copy-columns-in-a-dataset-and-compute-statistics-for-a-column/22157) I am using a [map operation](https://huggingface.co/docs/datasets/v2.14.0/en/package_reference/main_classes#datasets.Dataset.map) to first compute the metrics and a second map operation to apply them on the dataset. The problem lies in the second mapping, as it gets stuck at ~99%. By checking what the process does (using `htop` and `strace`) it seems to be doing a lot of I/O operations, and I'm not sure why. Obviously, I could always normalize the dataset externally and then load it using a loading script. However, since the internal dataset is updated fairly frequently, using the library to perform normalization automatically would make it much easier for me. ### Steps to reproduce the bug I'm able to reproduce the problem using the following scripts: ```python # random_data.py import datasets import torch _VERSION = "1.0.0" class RandomDataset(datasets.GeneratorBasedBuilder): def _info(self): return datasets.DatasetInfo( version=_VERSION, supervised_keys=None, features=datasets.Features( { "positions": datasets.Array2D( shape=(30000, 3), dtype="float32", ), "normals": datasets.Array2D( shape=(30000, 3), dtype="float32", ), "features": datasets.Array2D( shape=(30000, 6), dtype="float32", ), "scalars": datasets.Sequence( feature=datasets.Value("float32"), length=20, ), }, ), ) def _split_generators(self, dl_manager): return [ datasets.SplitGenerator( name=datasets.Split.TRAIN, # type: ignore gen_kwargs={"nb_samples": 1000}, ), datasets.SplitGenerator( name=datasets.Split.TEST, # type: ignore gen_kwargs={"nb_samples": 100}, ), ] def _generate_examples(self, nb_samples: int): for idx in range(nb_samples): yield idx, { "positions": torch.randn(30000, 3), "normals": torch.randn(30000, 3), "features": torch.randn(30000, 6), "scalars": torch.randn(20), } ``` ```python # main.py import datasets import torch def apply_mean_std( dataset: datasets.Dataset, means: dict[str, torch.Tensor], stds: dict[str, torch.Tensor], ) -> dict[str, torch.Tensor]: """Normalize the dataset using the mean and standard deviation of each feature. Args: dataset (`Dataset`): A huggingface dataset. mean (`dict[str, Tensor]`): A dictionary containing the mean of each feature. std (`dict[str, Tensor]`): A dictionary containing the standard deviation of each feature. Returns: dict: A dictionary containing the normalized dataset. """ result = {} for key in means.keys(): # extract data from dataset data: torch.Tensor = dataset[key] # type: ignore # extract mean and std from dict mean = means[key] # type: ignore std = stds[key] # type: ignore # normalize data normalized_data = (data - mean) / std result[key] = normalized_data return result # get dataset ds = datasets.load_dataset( path="random_data.py", split="train", ).with_format("torch") # compute mean (along last axis) means = {key: torch.zeros(ds[key][0].shape[-1]) for key in ds.column_names} means_sq = {key: torch.zeros(ds[key][0].shape[-1]) for key in ds.column_names} for batch in ds.iter(batch_size=8): for key in ds.column_names: data = batch[key] batch_size = data.shape[0] data = data.reshape(-1, data.shape[-1]) means[key] += data.mean(dim=0) / len(ds) * batch_size means_sq[key] += (data**2).mean(dim=0) / len(ds) * batch_size # compute std (along last axis) stds = {key: torch.sqrt(means_sq[key] - means[key] ** 2) for key in ds.column_names} # normalize each feature of the dataset ds_normalized = ds.map( desc="Applying mean/std", # type: ignore function=apply_mean_std, batched=False, fn_kwargs={ "means": means, "stds": stds, }, ) ``` ### Expected behavior Using the previous scripts, the `ds_normalized` mapping completes in ~5 minutes, but any subsequent use of `ds_normalized` is really really slow, for example reapplying `apply_mean_std` to `ds_normalized` takes forever. This is very strange, I'm sure I must be missing something, but I would still expect this to be faster. ### Environment info - `datasets` version: 2.13.1 - Platform: Linux-3.10.0-1160.66.1.el7.x86_64-x86_64-with-glibc2.17 - Python version: 3.10.12 - Huggingface_hub version: 0.15.1 - PyArrow version: 12.0.0 - Pandas version: 2.0.2

### Describe the bug I tried to load a music file using `datasets.load_dataset()` from the repository - https://huggingface.co/datasets/susnato/pop2piano_real_music_test I got the following error - ``` Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/susnato/anaconda3/envs/p2p/lib/python3.9/site-packages/datasets/arrow_dataset.py", line 2803, in __getitem__ return self._getitem(key) File "/home/susnato/anaconda3/envs/p2p/lib/python3.9/site-packages/datasets/arrow_dataset.py", line 2788, in _getitem formatted_output = format_table( File "/home/susnato/anaconda3/envs/p2p/lib/python3.9/site-packages/datasets/formatting/formatting.py", line 629, in format_table return formatter(pa_table, query_type=query_type) File "/home/susnato/anaconda3/envs/p2p/lib/python3.9/site-packages/datasets/formatting/formatting.py", line 398, in __call__ return self.format_column(pa_table) File "/home/susnato/anaconda3/envs/p2p/lib/python3.9/site-packages/datasets/formatting/formatting.py", line 442, in format_column column = self.python_features_decoder.decode_column(column, pa_table.column_names[0]) File "/home/susnato/anaconda3/envs/p2p/lib/python3.9/site-packages/datasets/formatting/formatting.py", line 218, in decode_column return self.features.decode_column(column, column_name) if self.features else column File "/home/susnato/anaconda3/envs/p2p/lib/python3.9/site-packages/datasets/features/features.py", line 1924, in decode_column [decode_nested_example(self[column_name], value) if value is not None else None for value in column] File "/home/susnato/anaconda3/envs/p2p/lib/python3.9/site-packages/datasets/features/features.py", line 1924, in <listcomp> [decode_nested_example(self[column_name], value) if value is not None else None for value in column] File "/home/susnato/anaconda3/envs/p2p/lib/python3.9/site-packages/datasets/features/features.py", line 1325, in decode_nested_example return schema.decode_example(obj, token_per_repo_id=token_per_repo_id) File "/home/susnato/anaconda3/envs/p2p/lib/python3.9/site-packages/datasets/features/audio.py", line 184, in decode_example array, sampling_rate = sf.read(f) File "/home/susnato/anaconda3/envs/p2p/lib/python3.9/site-packages/soundfile.py", line 372, in read with SoundFile(file, 'r', samplerate, channels, File "/home/susnato/anaconda3/envs/p2p/lib/python3.9/site-packages/soundfile.py", line 740, in __init__ self._file = self._open(file, mode_int, closefd) File "/home/susnato/anaconda3/envs/p2p/lib/python3.9/site-packages/soundfile.py", line 1264, in _open _error_check(_snd.sf_error(file_ptr), File "/home/susnato/anaconda3/envs/p2p/lib/python3.9/site-packages/soundfile.py", line 1455, in _error_check raise RuntimeError(prefix + _ffi.string(err_str).decode('utf-8', 'replace')) RuntimeError: Error opening <_io.BufferedReader name='/home/susnato/.cache/huggingface/datasets/downloads/d2b09cb974b967b13f91553297c40c0f02f3c0d4c8356350743598ff48d6f29e'>: Format not recognised. ``` ### Steps to reproduce the bug Code to reproduce the error - ```python from datasets import load_dataset ds = load_dataset("susnato/pop2piano_real_music_test", split="test") print(ds[0]) ``` ### Expected behavior I should be able to read the music file without any error. ### Environment info - `datasets` version: 2.14.0 - Platform: Linux-5.19.0-50-generic-x86_64-with-glibc2.35 - Python version: 3.9.16 - Huggingface_hub version: 0.15.1 - PyArrow version: 11.0.0 - Pandas version: 1.5.3

Thank you so much 🙌 \r\n\r\nIt's a bit of a custom setup, but in practice I am using a [pyarrow.fs.S3FileSystem](https://arrow.apache.org/docs/python/generated/pyarrow.fs.S3FileSystem.html) (wrapped in a `fsspec.implementations.arrow.ArrowFSWrapper` [to make it](https://arrow.apache.org/docs/python/filesystems.html#using-arrow-filesystems-with-fsspec) `fsspec` compatible). I also register it as an entrypoint with `fsspec` so that it's the one that gets automatically resolved when looking for filesystems for the `s3` protocol\r\n\r\nIn my case the `storage_option` that seemed not getting piped through was the filesystem's `endpoint_override` that I use in some tests to point at a mock S3 bucket" ]

### Describe the bug Since the latest release of `datasets` (`2.14.0`), custom filesystem `storage_options` passed to `load_dataset()` do not seem to propagate through all the way - leading to problems if loading data files that need those options to be set. I think this is because of the new `_prepare_path_and_storage_options()` (https://github.com/huggingface/datasets/pull/6028), which returns the right `storage_options` to use given a path and a `DownloadConfig` - but which might not be taking into account the extra `storage_options` explicitly provided e.g. through `load_dataset()` ### Steps to reproduce the bug ```python import fsspec import pandas as pd import datasets # Generate mock parquet file data_files = "demo.parquet" pd.DataFrame({"A": [1, 2, 3], "B": [4, 5, 6]}).to_parquet(data_files) _storage_options = {"x": 1, "y": 2} fs = fsspec.filesystem("file", **_storage_options) dataset = datasets.load_dataset( "parquet", data_files=data_files, storage_options=fs.storage_options ) ``` Looking at the `storage_options` resolved here: https://github.com/huggingface/datasets/blob/b0177910b32712f28d147879395e511207e39958/src/datasets/data_files.py#L331 they end up being `{}`, instead of propagating through the `storage_options` that were provided to `load_dataset` (`fs.storage_options`). As these then get used for the filesystem operation a few lines below https://github.com/huggingface/datasets/blob/b0177910b32712f28d147879395e511207e39958/src/datasets/data_files.py#L339 the call will fail if the user-provided `storage_options` were needed. --- A temporary workaround that seemed to work locally to bypass the problem was to bundle a duplicate of the `storage_options` into the `download_config`, so that they make their way all the way to `_prepare_path_and_storage_options()` and get extracted correctly: ```python dataset = datasets.load_dataset( "parquet", data_files=data_files, storage_options=fs.storage_options, download_config=datasets.DownloadConfig(storage_options={fs.protocol: fs.storage_options}), ) ``` ### Expected behavior `storage_options` provided to `load_dataset` take effect in all backend filesystem operations. ### Environment info datasets==2.14.0

### Describe the bug I've loaded a local image dataset with: `ds = laod_dataset("imagefolder", data_dir=path-to-data)` And defined a transform to process the data, following the Datasets docs. However, I get a keyError error, indicating there's no "image" key in my dataset. When I printed out the example_batch sent to the transformation function, it shows only the labels are being sent to the function. For some reason, the images are not in the example batches. ### Steps to reproduce the bug I'm using the latest stable version of datasets ### Expected behavior I expect the example_batches to contain both images and labels ### Environment info I'm using the latest stable version of datasets

[ "Sorry for asking a duplicate question about `num_proc`, I searched the forum and find the solution.\r\n\r\nBut I still can't make the trick with `torch.distributed.barrier()` to only map at the main process work. The [post on forum]( https://discuss.huggingface.co/t/slow-processing-with-map-when-using-deepspeed-or-fairscale/7229/7) didn't help.", "If it does the `map` twice then it means the hash of your map function is not some same between your two processes.\r\n\r\nCan you make sure your map functions have the same hash in different processes ?\r\n\r\n```python\r\nfrom datasets.fingerprint import Hasher\r\n\r\nprint(Hasher.hash(lambda x: cut_reorder_keys(x, num_stations_list=args.num_stations_list, is_pad=True, is_train=True)))\r\nprint(Hasher.hash(lambda x: random_shift(x, shift_range=(-160, 0), feature_scale=16)))\r\n```\r\n\r\nYou can also set the fingerprint used to reload the resulting dataset by passing `new_finegrprint=` in `map`, see https://huggingface.co/docs/datasets/v2.13.1/en/about_cache#the-cache.

### Describe the bug I use `torchrun --standalone --nproc_per_node=2 train.py` to start training. And write the code following the [docs](https://huggingface.co/docs/datasets/process#distributed-usage). The trick about using `torch.distributed.barrier()` to only execute map at the main process doesn't always work. When I am training model, it will map twice. When I am running a test for dataset and dataloader (just print the batches), it can work. Their code about loading dataset are same. And on another server with 30 CPU cores, I use 2 GPUs and it can't work neither. I have tried to use `rank` and `local_rank` to check, they all didn't make sense. ### Steps to reproduce the bug use `torchrun --standalone --nproc_per_node=2 train.py` or `torchrun --standalone train.py` to run This is my code: ```python if args.distributed and world_size > 1: if args.local_rank > 0: print(f"Rank {args.rank}: Gpu {args.gpu} waiting for main process to perform the mapping", force=True) torch.distributed.barrier() print("Mapping dataset") dataset = dataset.map(lambda x: cut_reorder_keys(x, num_stations_list=args.num_stations_list, is_pad=True, is_train=True), num_proc=8, desc="cut_reorder_keys") dataset = dataset.map(lambda x: random_shift(x, shift_range=(-160, 0), feature_scale=16), num_proc=8, desc="random_shift") dataset_test = dataset_test.map(lambda x: cut_reorder_keys(x, num_stations_list=args.num_stations_list, is_pad=True, is_train=False), num_proc=8, desc="cut_reorder_keys") if args.local_rank == 0: print("Mapping finished, loading results from main process") torch.distributed.barrier() ``` ### Expected behavior Only the main process will execute `map`, while the sub process will load cache from disk. ### Environment info server with 64 CPU cores (AMD Ryzen Threadripper PRO 5995WX 64-Cores) and 2 RTX 4090 - `python==3.9.16` - `datasets==2.13.1` - `torch==2.0.1+cu117` - `22.04.1-Ubuntu` server with 30 CPU cores (Intel(R) Xeon(R) Platinum 8375C CPU @ 2.90GHz) and 2 RTX 4090 - `python==3.9.0` - `datasets==2.13.1` - `torch==2.0.1+cu117` - `Ubuntu 20.04`

### Feature request My task is classification of a dataset containing a large label set that includes a hierarchy. Even ignoring the hierarchy I'm not able to find an example using `datasets` where the label names aren't hard-coded. This works find for classification of a handful of labels but ideally there would be a way of loading the name/id mappings required for `datasets.features.ClassLabel` from a file. It is possible to pass a file to ClassLabel but I cannot see an easy way of using this with `GeneratorBasedBuilder` since `self._info` is called before the `dl_manager` is constructed so even if my dataset contains say `label_mappings.json` there's no way of loading it in order to construct the `datasets.DatasetInfo` I can see other uses to accessing the `download_manager` from `self._info` - i.e. if the files contain a schema (i.e. `arrow` or `parquet` files) the `datasets.DatasetInfo` could be inferred. The workaround that was suggested in the forum is to generate a `.py` file from the `label_mappings.json` and import it. ``` class TestDatasetBuilder(datasets.GeneratorBasedBuilder): VERSION = datasets.Version("1.0.0") def _info(self): return datasets.DatasetInfo( description=_DESCRIPTION, features=datasets.Features( { "text": datasets.Value("string"), "label": datasets.features.ClassLabel(names=["label_1", "label_2"]), } ), task_templates=[TextClassification(text_column="text", label_column="label")], ) def _split_generators(self, dl_manager): train_path = dl_manager.download_and_extract(_TRAIN_DOWNLOAD_URL) test_path = dl_manager.download_and_extract(_TEST_DOWNLOAD_URL) return [ datasets.SplitGenerator(name=datasets.Split.TRAIN, gen_kwargs={"filepath": train_path}), datasets.SplitGenerator(name=datasets.Split.TEST, gen_kwargs={"filepath": test_path}), ] def _generate_examples(self, filepath): """Generate AG News examples.""" with open(filepath, encoding="utf-8") as csv_file: csv_reader = csv.DictReader(csv_file) for id_, row in enumerate(csv_reader): yield id_, row ``` ### Motivation Allow `datasets.DatasetInfo` to be generated based on the contents of the dataset. ### Your contribution I'm willing to work on a PR with guidence.

When I start a training task, **sometimes 1000examples/s, sometimes only 10examples/s.** ![image](https://github.com/huggingface/datasets/assets/46072190/cdc17661-8267-4fd8-b30c-b74d505efd9b) I'm not saying that speed is changing all the time. I mean, the reading speed is different in different training, which will cause me to start training over and over again until the speed of this generation of examples is normal.

### Describe the bug In #3627 and #5543, you tried to fix the host URL in The Pile datasets. But both URLs are not working now: `HTTPError: 404 Client Error: Not Found for URL: https://the-eye.eu/public/AI/pile_preliminary_components/PUBMED_title_abstracts_2019_baseline.jsonl.zst` And `ConnectTimeout: HTTPSConnectionPool(host='mystic.the-eye.eu', port=443): Max retries exceeded with url: /public/AI/pile_preliminary_components/PUBMED_title_abstracts_2019_baseline.jsonl.zst (Caused by ConnectTimeoutError(, 'Connection to mystic.the-eye.eu timed out. (connect timeout=10.0)'))` ### Steps to reproduce the bug ``` from datasets import load_dataset # This takes a few minutes to run, so go grab a tea or coffee while you wait :) data_files = "https://mystic.the-eye.eu/public/AI/pile_preliminary_components/PUBMED_title_abstracts_2019_baseline.jsonl.zst" pubmed_dataset = load_dataset("json", data_files=data_files, split="train") pubmed_dataset ``` Result: `ConnectTimeout: HTTPSConnectionPool(host='mystic.the-eye.eu', port=443): Max retries exceeded with url: /public/AI/pile_preliminary_components/PUBMED_title_abstracts_2019_baseline.jsonl.zst (Caused by ConnectTimeoutError(, 'Connection to mystic.the-eye.eu timed out.

### Describe the bug When using `Dataset.map` with `num_proc > 1`, the speed slows down much if I add `import torch` to the start of the script even though I don't use it. I'm not sure if it's `torch` only or if any other package that is "large" will also cause the same result. BTW, `import lightning` also slows it down. Below are the progress bars of `Dataset.map`, the only difference between them is with or without `import torch`, but the speed varies by 6-7 times. - without `import torch` ![image](https://github.com/huggingface/datasets/assets/47121592/0233055a-ced4-424a-9f0f-32a2afd802c2) - with `import torch` ![image](https://github.com/huggingface/datasets/assets/47121592/463eafb7-b81e-4eb9-91ca-fd7fe20f3d59) ### Steps to reproduce the bug Below is the code I used, but I don't think the dataset and the mapping function have much to do with the phenomenon. ```python3 from datasets import load_from_disk, disable_caching from transformers import AutoTokenizer # import torch # import lightning def rearrange_datapoints( batch, tokenizer, sequence_length, ): datapoints = [] input_ids = [] for x in batch['input_ids']: input_ids += x while len(input_ids) >= sequence_length: datapoint = input_ids[:sequence_length] datapoints.append(datapoint) input_ids[:sequence_length] = [] if input_ids: paddings = [-1] * (sequence_length - len(input_ids)) datapoint = paddings + input_ids if tokenizer.padding_side == 'left' else input_ids + paddings datapoints.append(datapoint) batch['input_ids'] = datapoints return batch if __name__ == '__main__': disable_caching() tokenizer = AutoTokenizer.from_pretrained('...', use_fast=False) dataset = load_from_disk('...') dataset = dataset.map( rearrange_datapoints, fn_kwargs=dict( tokenizer=tokenizer, sequence_length=2048, ), batched=True, num_proc=8, ) ``` ### Expected behavior The multi-processed `Dataset.map` function speed between with and without `import torch` should be the same. ### Environment info - `datasets` version: 2.13.1 - Platform: Linux-3.10.0-1127.el7.x86_64-x86_64-with-glibc2.31 - Python version: 3.10.11 - Huggingface_hub version: 0.14.1 - PyArrow version: 12.0.0 - Pandas version: 2.0.1

### Feature request I'm repeatedly finding myself in situations where I want to have a package called `datasets.py` or `evaluate.py` in my code and can't because those names are being taken up by Huggingface packages. While I can understand how (even from the user's perspective) it's aesthetically pleasing to have nice terse library names, ultimately a library hogging simple names like this is something I find short-sighted, impractical and at my most irritable, frankly rude. My preference would be a pattern like what you get with all the other big libraries like numpy or pandas: ``` import huggingface as hf # hf.transformers, hf.datasets, hf.evaluate ``` or things like ``` import huggingface.transformers as tf # tf.load_model(), etc ``` If this isn't possible for some technical reason, at least just call the packages something like `hf_transformers` and so on. I realize this is a very big change that's probably been discussed internally already, but I'm making this issue and sister issues on each huggingface project just to start the conversation and begin tracking community feeling on the matter, since I suspect I'm not the only one who feels like this. Sorry if this has been requested already on this issue tracker, I couldn't find anything looking for terms like "package name". Sister issues: - [transformers](https://github.com/huggingface/transformers/issues/24934) - **datasets** - [evaluate](https://github.com/huggingface/evaluate/issues/476) ### Motivation Not taking up package names the user is likely to want to use. ### Your contribution No - more a matter of internal discussion among core library authors.

[ "Hi! `_select_contiguous` fetches a (zero-copy) slice of the dataset's Arrow table to build a shard, so I don't think this part is the problem. To me, the issue seems to be the step where we embed external image files' bytes (a lot of file reads). You can use `.map` with multiprocessing to perform this step before `push_to_hub` in a faster manner and cache it to disk:\r\n```python\r\nfrom datasets.table import embed_table_storage\r\n# load_dataset(...)\r\nformat = dataset.format\r\ndataset = dataset.with_format(\"arrow\")\r\ndataset = dataset.map(embed_table_storage, batched=True)\r\ndataset = dataset.with_format(**format)\r\n# push_to_hub(...)\r\n```\r\n\r\n(In Datasets 3.0, these external bytes will be written to an Arrow file when generating a dataset to avoid this \"embed\" step)", "Hi, thanks, this solution saves some time.\r\nBut can't we avoid embedding all external image files bytes with each push, skipping the images that have already been pushed into the repo?\r\n\r\nEdit: Ok I missed the part of cache it manually on the disk the first time, this solves the problem. Thank you" ]

### Describe the bug For some reason when I try to resume the upload of my dataset, it is very slow to reach the index of the shard from which to resume the uploading. From my understanding, the problem is in this part of the code: arrow_dataset.py ```python for index, shard in logging.tqdm( enumerate(itertools.chain([first_shard], shards_iter)), desc="Pushing dataset shards to the dataset hub", total=num_shards, disable=not logging.is_progress_bar_enabled(), ): shard_path_in_repo = path_in_repo(index, shard) # Upload a shard only if it doesn't already exist in the repository if shard_path_in_repo not in data_files: ``` In particular, iterating the generator is slow during the call: ```python self._select_contiguous(start, length, new_fingerprint=new_fingerprint) ``` I wonder if it is possible to avoid calling this function for shards that are already uploaded and just start from the correct shard index. ### Steps to reproduce the bug 1.

Since we switched to the new HfFileSystem we no longer apply user's proxy and user-agent. Using the HTTP_PROXY and HTTPS_PROXY environment variables works though since we use aiohttp to call the HF Hub. This can be implemented in `_prepare_single_hop_path_and_storage_options`. Though ideally the `HfFileSystem` could support passing at least the proxies

### Describe the bug Attempting to save a dataset as a compressed csv file, the compression kwargs provided to `.to_csv()` that get piped to panda's `pandas.DataFrame.to_csv` do not have any effect - resulting in the dataset not getting compressed. A warning is raised if explicitly providing a `compression` kwarg, but no warnings are raised if relying on the defaults. This can lead to datasets secretly not getting compressed for users expecting the behaviour to match panda's `.to_csv()`, where the compression format is automatically inferred from the destination path suffix. ### Steps to reproduce the bug ```python # dataset is not compressed (but at least a warning is emitted) import datasets dataset = datasets.load_dataset("rotten_tomatoes", split="train") dataset.to_csv("uncompressed.csv") print(os.path.getsize("uncompressed.csv")) # 1008607 dataset.to_csv("compressed.csv.gz", compression={'method': 'gzip', 'compresslevel': 1, 'mtime': 1}) print(os.path.getsize("compressed.csv.gz")) # 1008607 ``` ```shell >>> RuntimeWarning: compression has no effect when passing a non-binary object as input. csv_str = batch.to_pandas().to_csv( ``` ```python # dataset is not compressed and no warnings are emitted dataset.to_csv("compressed.csv.gz") print(os.path.getsize("compressed.csv.gz")) # 1008607 # compare with dataset.to_pandas().to_csv("pandas.csv.gz") print(os.path.getsize("pandas.csv.gz")) # 418561 ``` --- I think that this is because behind the scenes `pandas.DataFrame.to_csv` is always called with a buf-like `path_or_buf`, but users that are providing a path-like to `datasets.Dataset.to_csv` are likely not to expect / know that - leading to a mismatch in their understanding of the expected behaviour of the `compression` kwarg. ### Expected behavior The dataset to be saved as a compressed csv file when providing a `compression` kwarg, or when relying on the default `compression='infer'` ### Environment info `datasets == 2.13.1`

### Describe the bug `load_dataset` allows loading a subset of columns from a parquet file with the `columns` argument. Since version 2.13, this produces the following error: ``` Traceback (most recent call last): File "/usr/lib/python3.10/site-packages/datasets/builder.py", line 1879, in _prepare_split_single for _, table in generator: File "/usr/lib/python3.10/site-packages/datasets/packaged_modules/parquet/parquet.py", line 68, in _generate_tables raise ValueError( ValueError: Tried to load parquet data with columns '['sepal_length']' with mismatching features '{'sepal_length': Value(dtype='float64', id=None), 'sepal_width': Value(dtype='float64', id=None), 'petal_length': Value(dtype='float64', id=None), 'petal_width': Value(dtype='float64', id=None), 'species': Value(dtype='string', id=None)}' ``` This seems to occur because `datasets` is checking whether the columns in the schema exactly match the provided list of columns, instead of whether they are a subset. ### Steps to reproduce the bug ```python # Prepare some sample data import pandas as pd iris = pd.read_csv('https://raw.githubusercontent.com/mwaskom/seaborn-data/master/iris.csv') iris.to_parquet('iris.parquet') # ['sepal_length', 'sepal_width', 'petal_length', 'petal_width', 'species'] print(iris.columns) # Load data with datasets from datasets import load_dataset # Load full parquet file dataset = load_dataset('parquet', data_files='iris.parquet') # Load column subset; throws error for datasets>=2.13 dataset = load_dataset('parquet', data_files='iris.parquet', columns=['sepal_length']) ``` ### Expected behavior No error should be thrown and the given column subset should be loaded. ### Environment info - `datasets` version: 2.13.0 - Platform: Linux-5.15.0-76-generic-x86_64-with-glibc2.35 - Python version: 3.10.9 - Huggingface_hub version: 0.16.4 - PyArrow version: 12.0.1 - Pandas version: 1.5.3

### Describe the bug load_dataset simply hangs. It happens once every ~5 times, and interestingly hangs for a multiple of 5 minutes (hangs for 5/10/15 minutes). Using the profiler in PyCharm shows that it spends the time at <method 'connect' of '_socket.socket' objects>. However, a local cache is available so I am not sure why socket is needed. ([profiler result](https://ibb.co/0Btbbp8)) It only happens on WSL for me. It works for native Windows and my MacBook. (cache quickly recognized and loaded within a second). ### Steps to reproduce the bug I am using Ubuntu 22.04.2 LTS (GNU/Linux 5.15.90.1-microsoft-standard-WSL2 x86_64) Python 3.10.10 (main, Mar 21 2023, 18:45:11) [GCC 11.2.0] on linux >>> import datasets >>> datasets.load_dataset('ai2_arc', 'ARC-Challenge') # hangs for 5/10/15 minutes ### Expected behavior cache quickly recognized and loaded within a second ### Environment info Please let me know if I should provide more environment information.

### Describe the bug I wanted to select only some columns of data. And I thought that's why the argument `input_columns` exists. What I expected is like this: If there are ["a", "b", "c", "d"] columns, and if I set `input_columns=["a", "d"]`, the data will have only ["a", "d"] columns. But it doesn't select columns. It preserves existing columns. The main cause is `update` function of `dictionary` type `transformed_batch`. https://github.com/huggingface/datasets/blob/682d21e94ab1e64c11b583de39dc4c93f0101c5a/src/datasets/iterable_dataset.py#L687-L691 `transformed_batch` gets all the columns by `transformed_batch = dict(batch)`. Even `function_args` selects `input_columns`, `update` preserves columns other than `input_columns`. I think it should take a new dictionary with columns in `input_columns` like this: ``` # transformed_batch = dict(batch) # transformed_batch.update(self.function(*function_args, **self.fn_kwargs) # This is what I think correct. transformed_batch = self.function(*function_args, **self.fn_kwargs) ``` Let me know how to use `input_columns`. ### Steps to reproduce the bug Described all above. ### Expected behavior Described all above. ### Environment info datasets: 2.12 python: 3.8

[ "`HfApi` comes from the `huggingface_hub` package. You can use [this](https://huggingface.co/docs/huggingface_hub/v0.16.3/en/package_reference/utilities#huggingface_hub.configure_http_backend) utility to change the `huggingface_hub`'s `Session` proxies (see the example).\r\n\r\nWe plan to implement https://github.com/huggingface/datasets/issues/5080 and make this behavior more consistent eventually.", "> this\r\n\r\nThanks. I will try `huggingface_hub.configure_http_backend` to change session's config.", "@mariosasko are you saying if I do the following:\r\n\r\n```\r\ndef backend_factory() -> requests.Session:\r\n session = requests.Session()\r\n session.proxies = {\r\n \"https\": \"127.0.0.1:8887\",\r\n \"http\": \"127.0.0.1:8887\",\r\n }\r\n session.verify = \"/etc/ssl/certs/ca-certificates.crt\"\r\n return session\r\n\r\n# Set it as the default session factory\r\nconfigure_http_backend(backend_factory=backend_factory)\r\n```\r\n\r\nwhich works nicely with transformer library:\r\n\r\n```\r\ndef download_gpt_2_model():\r\n tokenizer = GPT2Tokenizer.from_pretrained(\r\n \"gpt2\", force_download=True, resume_download=False\r\n )\r\n text = \"Replace me by any text you'd like.\"\r\n encoded_input = tokenizer(text, return_tensors=\"pt\")\r\n print(encoded_input)\r\n\r\n model = GPT2Model.from_pretrained(\r\n \"gpt2\", force_download=True, resume_download=False\r\n )\r\n output = model(**encoded_input)\r\n```\r\n\r\nshould work for datasets library as well ?\r\n\r\nIn my case if I just do:\r\n\r\n```\r\ndef download_sts12_sts_dataset():\r\n dataset = load_dataset(\r\n \"mteb/sts12-sts\",\r\n download_mode=\"force_redownload\",\r\n verification_mode=\"basic_checks\",\r\n revision=\"main\",\r\n )\r\n\r\n```\r\nI am getting:\r\n`ConnectionError: Couldn't reach https://huggingface.co/datasets/mteb/sts12-sts/resolve/main/dataset_infos.json (ConnectTimeout(MaxRetryError(\"HTTPSConnectionPool(host='huggingface.co', port=443): Max retries exceeded with url: /datasets/mteb/sts12-sts/resolve/main/dataset_infos.json (Caused by ConnectTimeoutError(<urllib3.connection.HTTPSConnection object at 0x7f429e87a3a0>, 'Connection to huggingface.co timed out.

Our download logic is a bit more complex (e.g., we also support downloading non-Hub files), so we are not aligned with them yet. In the meantime, it's best to use the env vars.", "@mariosasko I fully understand that the logic for dataset is different. I see 2 issues with the current implementation of the env variables:\r\n\r\n- having the same https_proxy/http_prox/no_proxy env variables for all tools is not good in some case. For example I have 2 differents proxy server. In 2019 we had discussion with the Tensorflow teams and they recommended to do the following: TFDS_HTTP_PROXY, TFDS_HTTPS_PROXY ...\r\n- with recent version of requests, it is not possible to deactivate TLS interception (verify=false) by using env variable. This is useful to debug things and in some case TLS is not working and you need to ignore verifying the SSL certificate (probably not recommended) \r\n\r\nOne of the best way is to able to pass our requests.Session() directly\r\n```\r\nimport openai\r\nsession = requests.Session()\r\nsession.cert = CERT\r\nsession.verify = False\r\nopenai.requestssession = session\r\n```\r\n\r\nMy 2 cents in this discussion" ]

### Describe the bug ```python download_config = DownloadConfig(proxies={'https': '<my proxy>'}) builder = load_dataset_builder(..., download_config=download_config) ``` But, when getting the dataset_info from HfApi, the http requests not using the proxies. ### Steps to reproduce the bug 1. Setup proxies in DownloadConfig. 2. Call `load_dataset_build` with download_config. 3. Inspect the call stack in HfApi.dataset_info. ![image](https://github.com/huggingface/datasets/assets/138426806/33e538a8-2e22-4e63-b634-343febe5324b) ### Expected behavior DownloadConfig.proxies works for getting dataset_info. ### Environment info https://github.com/huggingface/datasets/commit/406b2212263c0d33f267e35b917f410ff6b3bc00 Python 3.11.4

### Describe the bug I wrote `tokenize(examples)` function as an argument for `map` function for `IterableDataset`. It process dictionary type `examples` as a parameter. It is used in `train_dataset = train_dataset.map(tokenize, batched=True)` No error is raised. And then, I found some unnecessary keys and values in `examples` so I added `input_columns` argument to `map` function to select keys and values. It gives me an error saying ``` TypeError: tokenize() takes 1 positional argument but 3 were given. ``` The code below matters. https://github.com/huggingface/datasets/blob/406b2212263c0d33f267e35b917f410ff6b3bc00/src/datasets/iterable_dataset.py#L687 For example, `inputs = {"a":1, "b":2, "c":3}`. If `self.input_coluns` is `None`, `inputs` is a dictionary type variable and `function_args` becomes a `list` of a single `dict` variable. `function_args` becomes `[{"a":1, "b":2, "c":3}]` Otherwise, lets say `self.input_columns = ["a", "c"]` `[inputs[col] for col in self.input_columns]` results in `[1, 3]`. I think it should be `[{"a":1, "c":3}]`. I want to ask if the resulting format is intended. Maybe I can modify `tokenize()` to have 2 parameters in this case instead of having 1 dictionary. But this is confusing to me. Or it should be fixed as `[{col:inputs[col] for col in self.input_columns}]` ### Steps to reproduce the bug Run `map` function of `IterableDataset` with `input_columns` argument. ### Expected behavior `function_args` looks better to have same format. I think it should be `[{"a":1, "c":3}]`. ### Environment info dataset version: 2.12 python: 3.8

### Describe the bug Hi, I want to use the rotten tomatoes dataset but for a task other than classification, but when I interleave the dataset, it throws ```'ValueError: Column label is not present in features.'```. It seems that the label_col must be there in the dataset for some reason? Here is the full stacktrace ``` File "/home/suryahari/Vornoi/tryage-handoff-other-datasets.py", line 276, in create_dataloaders dataset = interleave_datasets(dsfold, stopping_strategy="all_exhausted") File "/home/suryahari/miniconda3/envs/vornoi/lib/python3.10/site-packages/datasets/combine.py", line 134, in interleave_datasets return _interleave_iterable_datasets( File "/home/suryahari/miniconda3/envs/vornoi/lib/python3.10/site-packages/datasets/iterable_dataset.py", line 1833, in _interleave_iterable_datasets info = DatasetInfo.from_merge([d.info for d in datasets]) File "/home/suryahari/miniconda3/envs/vornoi/lib/python3.10/site-packages/datasets/info.py", line 275, in from_merge dataset_infos = [dset_info.copy() for dset_info in dataset_infos if dset_info is not None] File "/home/suryahari/miniconda3/envs/vornoi/lib/python3.10/site-packages/datasets/info.py", line 275, in <listcomp> dataset_infos = [dset_info.copy() for dset_info in dataset_infos if dset_info is not None] File "/home/suryahari/miniconda3/envs/vornoi/lib/python3.10/site-packages/datasets/info.py", line 378, in copy return self.__class__(**{k: copy.deepcopy(v) for k, v in self.__dict__.items()}) File "<string>", line 20, in __init__ File "/home/suryahari/miniconda3/envs/vornoi/lib/python3.10/site-packages/datasets/info.py", line 208, in __post_init__ self.task_templates = [ File "/home/suryahari/miniconda3/envs/vornoi/lib/python3.10/site-packages/datasets/info.py", line 209, in <listcomp> template.align_with_features(self.features) for template in (self.task_templates) File "/home/suryahari/miniconda3/envs/vornoi/lib/python3.10/site-packages/datasets/tasks/text_classification.py", line 20, in align_with_features raise ValueError(f"Column {self.label_column} is not present in features.") ValueError: Column label is not present in features. ``` ### Steps to reproduce the bug Delete the column `labels` from the `rotten_tomatoes` dataset. Try to interleave it with other datasets. ### Expected behavior Should let me use the dataset with just the `text` field ### Environment info latest datasets library? I don't think this was an issue in earlier versions.

### Describe the bug I'm using a dataset with map and multiprocessing to run a function that returned a variable length list of outputs. This output list may be empty. Normally this is handled fine, but there is an edge case that crops up when using multiprocessing. In some cases, an empty list result ends up in a dataset shard consisting of a single item. This results in a `The features can't be aligned` error that is difficult to debug because it depends on the number of processes/shards used. I've reproduced a minimal example below. My current workaround is to fill empty results with a dummy value that I filter after, but this was a weird error that took a while to track down. ### Steps to reproduce the bug ```python import datasets dataset = datasets.Dataset.from_list([{'idx':i} for i in range(60)]) def test_func(row, idx): if idx==58: return {'output': []} else: return {'output' : [{'test':1}, {'test':2}]} # this works fine test1 = dataset.map(lambda row, idx: test_func(row, idx), with_indices=True, num_proc=4) # this fails test2 = dataset.map(lambda row, idx: test_func(row, idx), with_indices=True, num_proc=32) >ValueError: The features can't be aligned because the key output of features {'idx': Value(dtype='int64', id=None), 'output': Sequence(feature=Value(dtype='null', id=None), length=-1, id=None)} has unexpected type - Sequence(feature=Value(dtype='null', id=None), length=-1, id=None) (expected either [{'test': Value(dtype='int64', id=None)}] or Value("null"). ``` The error occurs during the check ```python _check_if_features_can_be_aligned([dset.features for dset in dsets]) ``` When the multiprocessing splitting lines up just right with the empty return value, one of the `dset` in `dsets` will have a single item with an empty list value, causing the error. ### Expected behavior Expected behavior is the result would be the same regardless of the `num_proc` value used. ### Environment info Datasets version 2.11.0 Python 3.9.16

Overview: The repository (huggingface/datasets-viewer) was recently archived and when I tried to run the code, there was the error message "AttributeError: module 'datasets.load' has no attribute 'prepare_module'". I could not resolve the issue myself due to lack of documentation of that attribute. Request: I kindly request the sharing of the code responsible for the dataset preview functionality or help with resolving the error. The dataset viewer on the Hugging Face website is incredibly useful since it is compatible with different types of inputs. It allows users to find datasets that meet their needs more efficiently. If needed, I am willing to contribute to the project by testing, documenting, and providing feedback on the dataset viewer code. Thank you for considering this request, and I look forward to your response.

### Feature request Currently adding a new column with `map` will cause all the data in the dataset to be duplicated and stored/cached on the disk again. It should reuse unchanged columns. ### Motivation This allows having datasets with different columns but sharing some basic columns. Currently, these datasets would become too expensive to store and one would need some kind of on-the-fly join; which also doesn't seem implemented. ### Your contribution _

### Feature request Currently using a `map` call processes and duplicates the whole dataset, which takes both time and disk space. The solution is to allow lazy mapping, which is essentially a saved chain of transforms that are applied on the fly whenever a slice of the dataset is requested. The API should look like `map`, as `set_transform` changes the current dataset while `map` returns another dataset. ### Motivation Lazy processing allows lower disk usage and faster experimentation. ### Your contribution _

### Describe the bug After loading `wiki_dpr` using: ```py ds = load_dataset(path='wiki_dpr', name='psgs_w100.multiset.compressed', split='train') print(ds.get_index("embeddings").metric_type) # prints nothing because the value is None ``` the index does not have a defined `metric_type`. This is an issue because I do not know how the `scores` are being computed for `get_nearest_examples()`. ### Steps to reproduce the bug System: Python 3.9.16, Transformers 4.30.2, WSL After loading `wiki_dpr` using: ```py ds = load_dataset(path='wiki_dpr', name='psgs_w100.multiset.compressed', split='train') print(ds.get_index("embeddings").metric_type) # prints nothing because the value is None ``` the index does not have a defined `metric_type`. This is an issue because I do not know how the `scores` are being computed for `get_nearest_examples()`. ```py from transformers import DPRQuestionEncoder, DPRContextEncoder, DPRQuestionEncoderTokenizer, DPRContextEncoderTokenizer tokenizer = DPRQuestionEncoderTokenizer.from_pretrained("facebook/dpr-question_encoder-multiset-base") encoder = DPRQuestionEncoder.from_pretrained("facebook/dpr-question_encoder-multiset-base") def encode_question(query, tokenizer=tokenizer, encoder=encoder): inputs = tokenizer(query, return_tensors='pt') question_embedding = encoder(**inputs)[0].detach().numpy() return question_embedding def get_knn(query, k=5, tokenizer=tokenizer, encoder=encoder, verbose=False): enc_question = encode_question(query, tokenizer, encoder) topk_results = ds.get_nearest_examples(index_name='embeddings', query=enc_question, k=k) a = torch.tensor(enc_question[0]).reshape(768) b = torch.tensor(topk_results.examples['embeddings'][0]) print(a.shape, b.shape) print(torch.dot(a, b)) print((a-b).pow(2).sum()) return topk_results ``` The [FAISS documentation](https://github.com/facebookresearch/faiss/wiki/MetricType-and-distances) suggests the metric is usually L2 distance (without the square root) or the inner product. I compute both for the sample query: ```py query = """ it catapulted into popular culture along with a line of action figures and other toys by Bandai.[2] By 2001, the media franchise had generated over $6 billion in toy sales. Despite initial criticism that its action violence targeted child audiences, the franchise has been commercially successful.""" get_knn(query,k=5) ``` Here, I get dot product of 80.6020 and L2 distance of 77.6616 and ```py NearestExamplesResults(scores=array([76.20431 , 75.312416, 74.945404, 74.866394, 74.68506 ], dtype=float32), examples={'id': ['3081096', '2004811', '8908258', '9594124', '286575'], 'text': ['actors, resulting in the "Power Rangers" franchise which has continued since then into sequel TV series (with "Power Rangers Beast Morphers" set to premiere in 2019), comic books, video games, and three feature films, with a further cinematic universe planned. Following from the success of "Power Rangers", Saban acquired the rights to more of Toei\'s library, creating "VR Troopers" and "Big Bad Beetleborgs" from several Metal Hero Series shows and "Masked Rider" from Kamen Rider Series footage. DIC Entertainment joined this boom by acquiring the rights to "Gridman the Hyper Agent" and turning it into "Superhuman Samurai Syber-Squad". In 2002,', ``` Doing `k=1` indicates the higher the outputted number, the better the match, so the metric should not be L2 distance. However, my manually computed inner product (80.6) has a discrepancy with the reported (76.2). Perhaps, this has to do with me using the `compressed` embeddings? ### Expected behavior ```py ds = load_dataset(path='wiki_dpr', name='psgs_w100.multiset.compressed', split='train') print(ds.get_index("embeddings").metric_type) # METRIC_INNER_PRODUCT ``` ### Environment info - `datasets` version: 2.12.0 - Platform: Linux-4.18.0-477.13.1.el8_8.x86_64-x86_64-with-glibc2.28 - Python version: 3.9.16 - Huggingface_hub version: 0.14.1 - PyArrow version: 12.0.0 - Pandas version: 2.0.1

Currently, `Dataset.__repr__` outputs a dataset's column names and the number of rows. We could improve it by printing its features and the first few rows. We should also implement `_repr_html_` to have a rich HTML representation in notebooks/Streamlit.

### Describe the bug Whenever I try to create a dataset which contains images using `Dataset.from_generator`, it freezes around 996 rows. I suppose it has something to do with memory consumption, but there's more memory available. I Somehow it worked a few times but mostly this makes the datasets library much more cumbersome to work with because generators are the easiest way to turn an existing dataset into a Hugging Face dataset. I've let it run in the frozen state for way longer than it can possibly take to load the actual dataset. Let me know if you have ideas how to resolve it! ### Steps to reproduce the bug ```python from datasets import Dataset import numpy as np def gen(): for row in range(10000): yield {"i": np.random.rand(512, 512, 3)} Dataset.from_generator(gen) # -> 90% of the time gets stuck around 1000 rows ``` ### Expected behavior Should continue and go through all the examples yielded by the generator, or at least throw an error or somehow communicate what's going on. ### Environment info - `datasets` version: 2.8.0 - Platform: Linux-5.15.0-52-generic-x86_64-with-glibc2.29 - Python version: 3.8.10 - PyArrow version: 12.0.1 - Pandas version: 1.5.1

### Describe the bug Hi everyone :) I have two local & custom datasets (1 "sentence" per line) which I split along the 95/5 lines for pre-training a Bert model. I use a modified version of `run_mlm.py` in order to be able to make use of `interleave_dataset`: - `tokenize()` runs fine - `group_text()` runs fine Everytime, on step 19, I get ```pytb File "env/lib/python3.9/site-packages/transformers/data/data_collator.py", line 779, in torch_mask_tokens inputs[indices_random] = random_words[indices_random] RuntimeError: Index put requires the source and destination dtypes match, got Float for the destination and Long for the source. ``` I tried: - training without interleave on dataset 1, it runs - training without interleave on dataset 2, it runs - training without `.to_iterable_dataset()`, it hangs then crash - training without group_text() and padding to max_length seemed to fix the issue, but who knows if this was just because it was an issue that would come much later in terms of steps. I might have coded something wrong, but I don't get what ### Steps to reproduce the bug I have this function: ```py def build_dataset(path: str, percent: str): dataset = load_dataset( "text", data_files={"train": [path]}, split=f"train[{percent}]" ) dataset = dataset.map( lambda examples: tokenize(examples["text"]), batched=True, num_proc=num_proc, ) dataset = dataset.map( group_texts, batched=True, num_proc=num_proc, desc=f"Grouping texts in chunks of {tokenizer.max_seq_length}", remove_columns=["text"] ) print(len(dataset)) return dataset.to_iterable_dataset() ``` I hardcoded group_text: ```py def group_texts(examples): # Concatenate all texts. concatenated_examples = {k: list(chain(*examples[k])) for k in examples.keys()} total_length = len(concatenated_examples[list(examples.keys())[0]]) # We drop the small remainder, and if the total_length < max_seq_length we exclude this batch and return an empty dict. # We could add padding if the model supported it instead of this drop, you can customize this part to your needs. total_length = (total_length // 512) * 512 # Split by chunks of max_len. result = { k: [t[i: i + 512] for i in range(0, total_length, 512)] for k, t in concatenated_examples.items() } # result = {k: [el for el in elements if el] for k, elements in result.items()} return result ``` And then I build datasets using the following code: ```py train1 = build_dataset("d1.txt", ":95%") train2 = build_dataset("d2.txt", ":95%") dev1 = build_dataset("d1.txt", "95%:") dev2 = build_dataset("d2.txt", "95%:") ``` and finally I run ```py train_dataset = interleave_datasets( [train1, train2], probabilities=[0.8, 0.2], seed=42 ) eval_dataset = interleave_datasets( [dev1, dev2], probabilities=[0.8, 0.2], seed=42 ) ``` Then I run the training part which remains mostly untouched: > CUDA_VISIBLE_DEVICES=1 python custom_dataset.py --model_type bert --per_device_train_batch_size 32 --do_train --output_dir /var/mlm/training-bert/model --max_seq_length 512 --save_steps 10000 --save_total_limit 3 --auto_find_batch_size --logging_dir ./logs-bert --learning_rate 0.0001 --do_train --num_train_epochs 25 --warmup_steps 10000 --max_step 45000 --fp16 ### Expected behavior The model should then train normally, but fails every time at the same step (19). printing the variables at `inputs[indices_random] = random_words[indices_random]` shows a magnificient empty tensor (, 32) [if I remember well] ### Environment info transformers[torch] 4.30.2 Ubuntu A100 0 CUDA 12 Driver Version: 525.116.04

### Describe the bug In the sort method,here's a piece of code ```python # column_names: Union[str, Sequence_[str]] # Check proper format of and for duplicates in column_names if not isinstance(column_names, list): column_names = [column_names] ``` I get an error when I pass in a tuple based on the column_names type annotation, it will raise an errror.As in the example below, while the type annotation implies that a tuple can be passed. ```python from datasets import load_dataset dataset = load_dataset('glue', 'ax')['test'] dataset.sort(column_names=('premise', 'hypothesis')) # Raise ValueError: Column '('premise', 'hypothesis')' not found in the dataset. ``` Of course, after I modified the tuple into a list, everything worked fine Change the code to the following so there will be no problem ```python # Check proper format of and for duplicates in column_names if not isinstance(column_names, list): if isinstance(column_names, str): column_names = [column_names] else: column_names = list(column_names) ``` ### Steps to reproduce the bug ```python from datasets import load_dataset dataset = load_dataset('glue', 'ax')['test'] dataset.sort(column_names=('premise', 'hypothesis')) # Raise ValueError: Column '('premise', 'hypothesis')' not found in the dataset. ``` ### Expected behavior Passing tuple into column_names should be equivalent to passing list ### Environment info - `datasets` version: 2.13.0 - Platform: macOS-13.1-arm64-arm-64bit - Python version: 3.10.11 - Huggingface_hub version: 0.15.1 - PyArrow version: 12.0.1 - Pandas version: 2.0.2

### Feature request I understand `dataset` provides a [`map`](https://github.com/huggingface/datasets/blob/main/src/datasets/arrow_dataset.py#L2849) function. This function in turn takes in a callable that is used to tokenize the text on which a model is trained. Frequently this text will not fit within a models's context window. In this case it would be useful to wrap around the text into multiple rows with each row fitting the model's context window. I tried to do it using this code as example which in turn I have borrowed from [here](https://stackoverflow.com/a/76343993/147530): ``` data = data.map(lambda samples: tokenizer(samples["text"], max_length=tokenizer.model_max_length, truncation=True, stride=4, return_overflowing_tokens=True), batched=True) ``` but running the code gives me this error: ``` File "/llm/fine-tune.py", line 117, in <module> data = data.map(lambda samples: tokenizer(samples["text"], max_length=tokenizer.model_max_length, truncation=True, stride=4, return_overflowing_tokens=True), batched=True) File "/llm/.env/lib/python3.9/site-packages/datasets/arrow_dataset.py", line 580, in wrapper out: Union["Dataset", "DatasetDict"] = func(self, *args, **kwargs) File "/llm/.env/lib/python3.9/site-packages/datasets/arrow_dataset.py", line 545, in wrapper out: Union["Dataset", "DatasetDict"] = func(self, *args, **kwargs) File "/llm/.env/lib/python3.9/site-packages/datasets/arrow_dataset.py", line 3087, in map for rank, done, content in Dataset._map_single(**dataset_kwargs): File "/llm/.env/lib/python3.9/site-packages/datasets/arrow_dataset.py", line 3480, in _map_single writer.write_batch(batch) File "/llm/.env/lib/python3.9/site-packages/datasets/arrow_writer.py", line 556, in write_batch pa_table = pa.Table.from_arrays(arrays, schema=schema) File "pyarrow/table.pxi", line 3798, in pyarrow.lib.Table.from_arrays File "pyarrow/table.pxi", line 2962, in pyarrow.lib.Table.validate File "pyarrow/error.pxi", line 100, in pyarrow.lib.check_status pyarrow.lib.ArrowInvalid: Column 1 named input_ids expected length 394 but got length 447 ``` The lambda function I have provided is correctly chopping up long text so it wraps around (and because of this 394 samples become 447 after wrap around) but the dataset `map` function does not like it. ### Motivation please see above ### Your contribution I'm afraid I don't have much knowledge to help

### Describe the bug Saving a dataset as parquet fails with a `ValueError: Table schema does not match schema used to create file` if the dataset was obtained out of a `.select_columns()` call with columns selected out of order. ### Steps to reproduce the bug ```python import datasets dataset = datasets.Dataset.from_dict( { "x1": [1, 2, 3], "x2": [10, 11, 12], } ) ds = dataset.select_columns(["x2", "x1"]) ds.to_parquet("demo.parquet") ``` ```shell >>> ValueError: Table schema does not match schema used to create file: table: x2: int64 x1: int64 -- schema metadata -- huggingface: '{"info": {"features": {"x2": {"dtype": "int64", "_type": "V' + 53 vs. file: x1: int64 x2: int64 -- schema metadata -- huggingface: '{"info": {"features": {"x1": {"dtype": "int64", "_type": "V' + 53 ``` --- I think this is because after the `.select_columns()` call with out of order columns, the output dataset features' schema ends up being out of sync with the schema of the arrow table backing it. ```python ds.features.arrow_schema >>> x1: int64 x2: int64 -- schema metadata -- huggingface: '{"info": {"features": {"x1": {"dtype": "int64", "_type": "V' + 53 ds.data.schema >>> x2: int64 x1: int64 -- schema metadata -- huggingface: '{"info": {"features": {"x2": {"dtype": "int64", "_type": "V' + 53 ``` So when we call `.to_parquet()`, the call behind the scenes to `datasets.io.parquet.ParquetDatasetWriter(...).write()` which initialises the backend `pyarrow.parquet.ParquetWriter` with `schema = self.dataset.features.arrow_schema` triggers `pyarrow` on write when [it checks](https://github.com/apache/arrow/blob/11b140a734a516e436adaddaeb35d23f30dcce44/python/pyarrow/parquet/core.py#L1086-L1090) that the `ParquetWriter` schema matches the schema of the table being written 🙌 https://github.com/huggingface/datasets/blob/6ed837325cb539a5deb99129e5ad181d0269e050/src/datasets/io/parquet.py#L139-L141 ### Expected behavior The dataset gets successfully saved as parquet. *In the same way as it does if saving it as csv: ```python import datasets dataset = datasets.Dataset.from_dict( { "x1": [1, 2, 3], "x2": [10, 11, 12], } ) ds = dataset.select_columns(["x2", "x1"]) ds.to_csv("demo.csv") ``` ### Environment info `python==3.11` `datasets==2.13.1`

[ "#self-assign\n\nHi @lhoestq 👋🏼\n\nI’d like to work on this!\n\nPlanning to support progress tracking with `map()` using any joblib backend (like \"loky\") by replacing the Queue-based approach in `iflatmap_unordered` with a file-based progress tracking mechanism (e.g. shared temp file with periodic updates).\n\nThis would allow the progress bar to work even in backends where inter-process Queues aren't supported. Let me know if this sounds good — I’ll get started!\n", "I think ideally it should have a general solution, since some joblib backends don't have a shared filesystem" ]

We recently enabled the (experimental) parallel backend switch for data download and extraction but not for `map` yet. Right now we're using our `iflatmap_unordered` implementation for multiprocessing that uses a shared Queue to gather progress updates from the subprocesses and show a progress bar in the main process. If a Queue implementation that would work on any joblib backend by leveraging the filesystem that is shared among workers, we can have `iflatmap_unordered` for joblib and therefore a `map` with any joblib backend with a progress bar ! Note that the Queue doesn't need to be that optimized though since we can choose a small frequency for progress updates (like 1 update per second).

### Describe the bug Related to https://github.com/huggingface/transformers/issues/24441. Not sure if this is a tokenizer issue or caching issue, so filing in both. Passing the tokenizer to the dataset map function causes the tokenizer to be fingerprinted weirdly. After calling the tokenizer with arguments like padding and truncation the tokenizer object changes interanally, even though the hash remains the same. But dumps is able to detect that internal change which causes the tokenizer object's fingerprint to change. ### Steps to reproduce the bug ```python from transformers import AutoTokenizer from datasets.utils.py_utils import dumps # Huggingface datasets t = AutoTokenizer.from_pretrained('bert-base-uncased') t.save_pretrained("tok1") th1 = hash(dumps(t)) text = "This is an example text" ttext = t(text, max_length=512, padding="max_length", truncation=True) t.save_pretrained("tok2") th2 = hash(dumps(t)) assert th1 == th2 # Assertion Error ``` But if you use just the hash of the object without dumps, the hashes don't change ```python from transformers import AutoTokenizer from datasets.utils.py_utils import dumps # Huggingface datasets t = AutoTokenizer.from_pretrained('bert-base-uncased') th1 = hash(t) # Just hash no dumps text = "This is an example text" ttext = t(text, max_length=512, padding="max_length", truncation=True) th2 = hash(t) # Just hash no dumps assert th1 == th2 # This is OK ``` This causes situations such as the following 1. Create a text file like this `yes "This is an example text" | head -n 10000 > lines.txt` ```python from transformers import AutoTokenizer import datasets class TokenizeMapper(object): """Mapper for tokenizer. This is needed because the caching mechanism of HuggingFace does not work on lambdas. Each time a new lambda will be created by a new process which will lead to a different hash. This way we can have a universal mapper object in init and reuse it with the same hash for each process. """ def __init__(self, tokenizer): """Initialize the tokenizer.""" self.tokenizer = tokenizer def __call__(self, examples, **kwargs): """Run the mapper.""" texts = examples["text"] tt = self.tokenizer(texts, max_length=256, padding="max_length", truncation=True) batch_outputs = { "input_ids": tt.input_ids, "attention_mask": tt.attention_mask, } return batch_outputs t = AutoTokenizer.from_pretrained('bert-base-uncased') mapper = TokenizeMapper(t) ds = datasets.load_dataset("text", data_files="lines.txt") mds1 = ds.map( mapper, batched=False, remove_columns=["text"], ).with_format("torch") mds2 = ds.map( mapper, batched=False, remove_columns=["text"], ).with_format("torch") ``` The second call to map should reuse the cached processed dataset from mds1, but it instead it redoes the tokenization because of the behavior of dumps. ### Expected behavior We should be able to initialize a tokenizer. And reusing it should let us reuse the same map computation for the same dataset. The second call to map should reuse the cached processed dataset from mds1, but it instead it redoes the tokenization because of the behavior of dumps. ### Environment info - `datasets` version: 2.13.0 - Platform: Linux-6.1.31_1-x86_64-with-glibc2.36 - Python version: 3.9.16 - Huggingface_hub version: 0.15.1 - PyArrow version: 12.0.1 - Pandas version: 2.0.2

### Feature request Minimal Example ``` import torch from datasets import IterableDataset d = IterableDataset.from_file(<file_name>) dl = torch.utils.data.dataloader.DataLoader(d,num_workers=3) for sample in dl: print(sample) ``` Warning: Too many dataloader workers: 2 (max is dataset.n_shards=1). Stopping 1 dataloader workers. To parallelize data loading, we give each process some shards (or data sources) to process. Therefore it's unnecessary to have a number of workers greater than dataset.n_shards=1. To enable more parallelism, please split the dataset in more files than 1. Expected Behavior: Dataset is sharded each cpu uses subset (contiguously - so you can do checkpoint loading/saving) ### Motivation I have a lot of unused cpu's and would like to be able to shard iterable datasets with pytorch's dataloader when num_workers > 1. This is for a very large single file. I am aware that we can use the `split_dataset_by_node` to ensure that each node (for distributed) gets different shards, but we should extend it so that this also continues for multiple workers. ### Your contribution If someone points me to what needs to change, I can create a PR.

### Describe the bug When using the newer pytorch 3.10 kernel, only 2 cores are being used by huggingface filter and map functions. The Pytorch 3.9 kernel would use as many cores as specified in the num_proc field. We have solved this in our own code by placing the following snippet in the code that is called inside subprocesses: ```os.sched_setaffinity(0, {i for i in range(1000)})``` The problem, as near as we can tell, us that once upon a time, cpu affinity was set using a bitmask ("0xfffff" and the like), and affinity recently changed to a list of processors rather than to using the mask. As such, only processors 1 and 17 are shown to be working in htop. ![Selection_072](https://github.com/huggingface/datasets/assets/107141022/04c5a824-5321-4531-afca-7bc84dff36b4) When running functions via `map`, the above resetting of affinity works to spread across the cores. When using `filter`, however, only two cores are active. ### Steps to reproduce the bug Repro steps: 1. Create an aws sagemaker instance 2. use the pytorch 3_10 kernel 3. Load a dataset 4. run a filter operation 5. watch as only 2 cores are used when num_proc > 2 6. run a map operation 7. watch as only 2 cores are used when num_proc > 2 8. run a map operation with processor affinity reset inside the function called via map 9. Watch as all cores run ### Expected behavior All specified cores are used via the num_proc argument. ### Environment info AWS sagemaker with the following init script run in the terminal after instance creation: conda init bash bash conda activate pytorch_p310 pip install Wand PyPDF pytesseract datasets seqeval pdfplumber transformers pymupdf sentencepiece timm donut-python accelerate optimum xgboost python -m pip install 'git+https://github.com/facebookresearch/detectron2.git' sudo yum -y install htop sudo yum -y update sudo yum -y install wget libstdc++ autoconf automake libtool autoconf-archive pkg-config gcc gcc-c++ make libjpeg-devel libpng-devel libtiff-devel zlib-devel

### Describe the bug When trying to stream a dataset i get the following error after a few minutes of waiting. ``` FileNotFoundError: https://huggingface.co/datasets/facebook/voxpopuli/resolve/main/data/n_files.json If the repo is private or gated, make sure to log in with `huggingface-cli login`. ``` I have already set the proxy environment variables. Downloading a Dataset without streaming works as expected. Still i suspect that this is connected to being behind a proxy. Is there a way to set the proxy for streaming datasets? Possibly a keyword argument that gets passed to ffspec? ### Steps to reproduce the bug This is the code i use. ``` import os os.environ['http_proxy'] = "http://example.com:xxxx" os.environ['https_proxy'] = "http://example.com:xxxx" from datasets import load_dataset ds = load_dataset("facebook/voxpopuli", name="de", streaming=True) ``` ### Expected behavior I would expect the streaming functionality to use the set proxy settings. ### Environment info - `datasets` version: 2.13.0 - Platform: Linux-5.15.0-73-generic-x86_64-with-glibc2.35 - Python version: 3.10.11 - Huggingface_hub version: 0.15.1 - PyArrow version: 11.0.0 - Pandas version: 2.0.2

The page https://huggingface.co/docs/datasets/repository_structure explains how to create a simple repository structure without a dataset script. It's the simplest way to create a dataset and should be easier to find, particularly on the docs' first pages.

### Describe the bug When uploading a dataset created locally using `from_dict` with a specified `description` field. It appears before upload, but is missing after upload and re-download. ### Steps to reproduce the bug I think the most relevant pattern in the code might be the following lines: ``` description_json_str = json.dumps( { "dataset_id": dataset.spec.dataset_id, "env_name": dataset.spec.env_spec.id, "action_space": serialize_space(dataset.spec.action_space), "observation_space": serialize_space(dataset.spec.observation_space), } ) hugging_face_dataset = Dataset.from_dict( episodes_dict, info=DatasetInfo(description=description_json_str) ) ``` Which comes from this function https://github.com/balisujohn/minarai/blob/8e023727f0a8488c4451651d9f7a79b981412c40/minari/integrations/hugging_face.py#L39 To replicate, clone this branch of my Minari fork https://github.com/balisujohn/minarai/tree/dev-huggingface then run ``` python3.8 -m venv env source env/bin/activate python3 -m pip install -e . python3 -m pip install pytest ``` The change the hugging face repo path in the test called `test_hugging_face_push_and_pull_dataset` in `tests/integrations/test_hugging_face.py` to one you have permissions to write to. Then run: ``` pytest tests/integrations/test_hugging_face.py::test_hugging_face_push_and_pull_dataset ``` ### Expected behavior DATASET INFO BEFORE UPLOADING DatasetInfo(description='{"dataset_id": "dummy-combo-test-v0", "env_name": "DummyComboEnv-v0", "action_space": "{\\"type\\": \\"Tuple\\", \\"subspaces\\": [{\\"type\\": \\"Box\\", \\"dtype\\": \\"float32\\", \\"shape\\": [1], \\"low\\": [2.0], \\"high\\": [3.0]}, {\\"type\\": \\"Box\\", \\"dtype\\": \\"float32\\", \\"shape\\": [1], \\"low\\": [4.0], \\"high\\": [5.0]}]}", "observation_space": "{\\"type\\": \\"Tuple\\", \\"subspaces\\": [{\\"type\\": \\"Box\\", \\"dtype\\": \\"float32\\", \\"shape\\": [1], \\"low\\": [2.0], \\"high\\": [3.0]}, {\\"type\\": \\"Tuple\\", \\"subspaces\\": [{\\"type\\": \\"Box\\", \\"dtype\\": \\"float32\\", \\"shape\\": [1], \\"low\\": [2.0], \\"high\\": [3.0]}, {\\"type\\": \\"Dict\\", \\"subspaces\\": {\\"component_1\\": {\\"type\\": \\"Box\\", \\"dtype\\": \\"float32\\", \\"shape\\": [1], \\"low\\": [-1.0], \\"high\\": [1.0]}, \\"component_2\\": {\\"type\\": \\"Dict\\", \\"subspaces\\": {\\"subcomponent_1\\": {\\"type\\": \\"Box\\", \\"dtype\\": \\"float32\\", \\"shape\\": [1], \\"low\\": [2.0], \\"high\\": [3.0]}, \\"subcomponent_2\\": {\\"type\\": \\"Tuple\\", \\"subspaces\\": [{\\"type\\": \\"Box\\", \\"dtype\\": \\"float32\\", \\"shape\\": [1], \\"low\\": [4.0], \\"high\\": [5.0]}, {\\"type\\": \\"Discrete\\", \\"dtype\\": \\"int64\\", \\"start\\": 0, \\"n\\": 10}]}}}}}]}]}"}', citation='', homepage='', license='', features={'observations': {'_index_0': Sequence(feature=Value(dtype='float32', id=None), length=-1, id=None), '_index_1': {'_index_0': Sequence(feature=Value(dtype='float32', id=None), length=-1, id=None), '_index_1': {'component_1': Sequence(feature=Value(dtype='float32', id=None), length=-1, id=None), 'component_2': {'subcomponent_1': Sequence(feature=Value(dtype='float32', id=None), length=-1, id=None), 'subcomponent_2': {'_index_0': Sequence(feature=Value(dtype='float32', id=None), length=-1, id=None), '_index_1': Value(dtype='int64', id=None)}}}}}, 'actions': {'_index_0': Sequence(feature=Value(dtype='float32', id=None), length=-1, id=None), '_index_1': Sequence(feature=Value(dtype='float32', id=None), length=-1, id=None)}, 'rewards': Value(dtype='int64', id=None), 'truncations': Value(dtype='bool', id=None), 'terminations': Value(dtype='bool', id=None), 'episode_ids': Value(dtype='int64', id=None)}, post_processed=None, supervised_keys=None, task_templates=None, builder_name=None, config_name=None, version=None, splits=None, download_checksums=None, download_size=None, post_processing_size=None, dataset_size=None, size_in_bytes=None) ...

### Describe the bug We don't need to pass `use_auth_token=True` anymore to download gated datasets or models, so the following should work if correctly logged in. ```py from datasets import load_dataset load_dataset("mozilla-foundation/common_voice_6_1", "tr", split="train+validation") ``` However it throws an error - probably because something weird is hardcoded into the dataset loading script. ### Steps to reproduce the bug 1.) ``` huggingface-cli login ``` 2.) Make sure that you have accepted the license here: https://huggingface.co/datasets/mozilla-foundation/common_voice_6_1 3.) Run: ```py from datasets import load_dataset load_dataset("mozilla-foundation/common_voice_6_1", "tr", split="train+validation") ``` 4.) You'll get: ``` File ~/hf/lib/python3.10/site-packages/datasets/builder.py:963, in DatasetBuilder._download_and_prepare(self, dl_manager, verification_mode, **prepare_split_kwargs) 961 split_dict = SplitDict(dataset_name=self.name) 962 split_generators_kwargs = self._make_split_generators_kwargs(prepare_split_kwargs) --> 963 split_generators = self._split_generators(dl_manager, **split_generators_kwargs) 965 # Checksums verification 966 if verification_mode == VerificationMode.ALL_CHECKS and dl_manager.record_checksums: File ~/.cache/huggingface/modules/datasets_modules/datasets/mozilla-foundation--common_voice_6_1/f4d7854c466f5bd4908988dbd39044ec4fc634d89e0515ab0c51715c0127ffe3/common_voice_6_1.py:150, in CommonVoice._split_generators(self, dl_manager) 148 hf_auth_token = dl_manager.download_config.use_auth_token 149 if hf_auth_token is None: --> 150 raise ConnectionError( 151 "Please set use_auth_token=True or use_auth_token='<TOKEN>' to download this dataset" 152 ) 154 bundle_url_template = STATS["bundleURLTemplate"] 155 bundle_version = bundle_url_template.split("/")[0] ConnectionError: Please set use_auth_token=True or use_auth_token='<TOKEN>' to download this dataset ``` ### Expected behavior One should not have to pass `use_auth_token=True`.

### Describe the bug Performing a `.map` method on a dataset loses it's config name / split name only if run with multiproc ### Steps to reproduce the bug ```python from datasets import Audio, load_dataset from transformers import AutoFeatureExtractor import numpy as np # load dummy dataset libri = load_dataset("hf-internal-testing/librispeech_asr_dummy", "clean") # make train / test splits libri = libri["validation"].train_test_split(seed=42, shuffle=True, test_size=0.1) # example feature extractor model_id = "ntu-spml/distilhubert" feature_extractor = AutoFeatureExtractor.from_pretrained(model_id, do_normalize=True, return_attention_mask=True) sampling_rate = feature_extractor.sampling_rate libri = libri.cast_column("audio", Audio(sampling_rate=sampling_rate)) max_duration = 30.0 def preprocess_function(examples): audio_arrays = [x["array"] for x in examples["audio"]] inputs = feature_extractor( audio_arrays, sampling_rate=feature_extractor.sampling_rate, max_length=int(feature_extractor.sampling_rate * max_duration), truncation=True, return_attention_mask=True, ) return inputs # single proc map libri_encoded = libri.map( preprocess_function, remove_columns=["audio", "file"], batched=True, num_proc=1 ) print(10 * "=" ,"Single processing", 10 * "=") print("Config name before: ", libri["train"].config_name, " Split name before: ", libri["train"].split) print("Config name after: ", libri_encoded["train"].config_name, " Split name after: ", libri_encoded["train"].split) # multi proc map libri_encoded = libri.map( preprocess_function, remove_columns=["audio", "file"], batched=True, num_proc=2 ) print(10 * "=" ,"Multi processing", 10 * "=") print("Config name before: ", libri["train"].config_name, " Split name before: ", libri["train"].split) print("Config name after: ", libri_encoded["train"].config_name, " Split name after: ", libri_encoded["train"].split) ``` **Print Output:** ``` ========== Single processing ========== Config name before: clean Split name before: validation Config name after: clean Split name after: validation ========== Multi processing ========== Config name before: clean Split name before: validation Config name after: None Split name after: None ``` => we can see that the config/split names are lost in the multiprocessing setting ### Expected behavior Should retain both config / split names in the multiproc setting ### Environment info - `datasets` version: 2.13.1.dev0 - Platform: Linux-5.15.0-67-generic-x86_64-with-glibc2.35 - Python version: 3.10.6 - Huggingface_hub version: 0.15.1 - PyArrow version: 12.0.0 - Pandas version: 2.0.2

### Describe the bug When doing a map of a dataset with complex types, sometimes `datasets` is unable to interpret the valid schema of a returned datasets.map() function. This often comes from conflicting types, like when both empty lists and filled lists are competing for the same field value. This is prone to happen in batch mapping, when the mapper returns a sequence of null/empty values and other batches are non-null. A workaround is to manually cast the new batch to a pyarrow table (like implemented in this [workaround](https://github.com/piercefreeman/lassen/pull/3)) but it feels like this ideally should be solved at the core library level. Note that the reproduction case only throws this error if the first datapoint has the empty list. If it is processed later, datasets already detects its representation as list-type and therefore allows the empty list to be provided. ### Steps to reproduce the bug A trivial reproduction case: ```python from typing import Iterator, Any import pandas as pd from datasets import Dataset def batch_to_examples(batch: dict[str, list[Any]]) -> Iterator[dict[str, Any]]: for i in range(next(iter(lengths))): yield {feature: values[i] for feature, values in batch.items()} def examples_to_batch(examples) -> dict[str, list[Any]]: batch = {} for example in examples: for feature, value in example.items(): if feature not in batch: batch[feature] = [] batch[feature].append(value) return batch def batch_process(examples, explicit_schema: bool): new_examples = [] for example in batch_to_examples(examples): new_examples.append(dict(texts=example["raw_text"].split())) return examples_to_batch(new_examples) df = pd.DataFrame( [ {"raw_text": ""}, {"raw_text": "This is a test"}, {"raw_text": "This is another test"}, ] ) dataset = Dataset.from_pandas(df) # datasets won't be able to typehint a dataset that starts with an empty example. with pytest.raises(TypeError, match="Couldn't cast array of type"): dataset = dataset.map( batch_process, batched=True, batch_size=1, num_proc=1, remove_columns=dataset.column_names, ) ``` This results in crashes like: ```bash File "/Users/piercefreeman/Library/Caches/pypoetry/virtualenvs/example-9kBqeSPy-py3.11/lib/python3.11/site-packages/datasets/table.py", line 1819, in wrapper return func(array, *args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/piercefreeman/Library/Caches/pypoetry/virtualenvs/example-9kBqeSPy-py3.11/lib/python3.11/site-packages/datasets/table.py", line 2109, in cast_array_to_feature return array_cast(array, feature(), allow_number_to_str=allow_number_to_str) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/piercefreeman/Library/Caches/pypoetry/virtualenvs/example-9kBqeSPy-py3.11/lib/python3.11/site-packages/datasets/table.py", line 1819, in wrapper return func(array, *args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/piercefreeman/Library/Caches/pypoetry/virtualenvs/example-9kBqeSPy-py3.11/lib/python3.11/site-packages/datasets/table.py", line 1998, in array_cast raise TypeError(f"Couldn't cast array of type {array.type} to {pa_type}") TypeError: Couldn't cast array of type string to null ``` ### Expected behavior The code should successfully map and create a new dataset without error. ### Environment info Mac OSX, Linux

### Describe the bug I've been using the train_test_split method in the datasets module to split my HuggingFace Dataset into separate training, validation, and testing subsets. However, I've noticed an issue where the split datasets appear to maintain the same underlying PyArrow Table. ### Steps to reproduce the bug 1. Load any dataset ```dataset = load_dataset("lhoestq/demo1")``` 2. Try the next code: ```python from datasets import Dataset, DatasetDict train_size = 0.6 split_train = dataset["train"].train_test_split( train_size=train_size, ) separate_dataset_dict = DatasetDict({ "train": split_train["train"], "test": split_train["test"], }) ``` 3. The next code ```print(separate_dataset_dict)``` when printing the dataset it gives the indication that they have 3 and 2 rows respectively. 4. But the next code: ```python print(len(separate_dataset_dict["train"].data['id'])) print(len(separate_dataset_dict["test"].data['id'])) ``` Indicates that both tables still have 5 rows. ### Expected behavior However, I've noticed that train_test_split["train"].data, test_val_split["train"].data, and test_val_split["test"].data are identical, suggesting that they all point to the same underlying PyArrow Table. This means that the split datasets are not independent, as I expected. I believe this is a bug in the train_test_split implementation, as I would expect this function to return datasets with separate underlying PyArrow Tables. Could you please help me understand if this is expected behavior, or if there's a workaround to create truly independent split datasets? I would appreciate any assistance with this issue. Thank you. ### Environment info I tried in Colab: - `datasets` version: 2.13.0 - Platform: Windows-10-10.0.22621-SP0 - Python version: 3.10.11 - Huggingface_hub version: 0.14.1 - PyArrow version: 12.0.0 - Pandas version: 2.0.1 and my PC: - `datasets` version: 2.13.0 - Platform: Linux-5.15.107+-x86_64-with-glibc2.31 - Python version: 3.10.12 - Huggingface_hub version: 0.15.1 - PyArrow version: 9.0.0 - Pandas version: 1.5.3

There are two ways an iterable dataset can be split by node: 1. if the number of shards is a factor of number of GPUs: in that case the shards are evenly distributed per GPU 2. otherwise, each GPU iterate on the data and at the end keeps 1 sample out of n(GPUs) - skipping the others. In case 2. it's therefore possible to have the same examples passed to `prepare_dataset` for each GPU. This doesn't sound optimized though, because it runs the preprocessing on samples that won't be used in the end. Could you open a new issue so that we can discuss about this and find a solution ? _Originally posted by @lhoestq in https://github.com/huggingface/datasets/issues/5360#issuecomment-1592729051_

### Describe the bug Currently, The server is off-line. I am using the glue metric from the local file downloaded from the hub. I download / cached datasets using `load_dataset('glue','sst2', cache_dir='/xxx')` to cache them and then in the off-line mode, I use `load_dataset('xxx/glue.py','sst2', cache_dir='/xxx')`. I can successfully reuse cached datasets. My problem is about the load_metric. When I run `load_dataset('xxx/glue_metric.py','sst2',cache_dir='/xxx')` , it returns ` File "xx/lib64/python3.9/site-packages/datasets/utils/deprecation_utils.py", line 46, in wrapper return deprecated_function(*args, **kwargs) File "xx//lib64/python3.9/site-packages/datasets/load.py", line 1392, in load_metric metric = metric_cls( TypeError: 'NoneType' object is not callable` Thanks in advance for help! ### Steps to reproduce the bug N/A ### Expected behavior N/A ### Environment info `datasets == 2.12.0`
