🔍 Model Testing Results

The fine-tuned model has been tested with various prompts:

Test 1: Bangladesh News

Prompt: "The latest news from Bangladesh"
Generated: Economic analysis with realistic GDP and inflation data

Test 2: Opinion Piece

Prompt: "In today's opinion piece"
Generated: Political commentary style content

Test 3: Government Policy

Prompt: "Government announces new policy"
Generated: Policy announcement format

🚀 Quick Start

1. Load and Use the Model

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

# Load the fine-tuned model
tokenizer = AutoTokenizer.from_pretrained("./prothomalo_model/final_model")
model = AutoModelForCausalLM.from_pretrained("./prothomalo_model/final_model")

# Generate text
prompt = "The latest news from Bangladesh"
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_length=150, do_sample=True, temperature=0.8)
generated_text = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(generated_text)

2. Use Safetensors Format

from safetensors import safe_open
import torch

# Load model weights directly
with safe_open("prothomalo_model.safetensors", framework="pt", device=0) as f:
    print(f"Available tensors: {len(f.keys())}")
    for key in list(f.keys())[:5]:  # Show first 5 keys
        tensor = f.get_tensor(key)
        print(f"{key}: {tensor.shape}")

🛠️ Training Pipeline

The complete training pipeline includes:

1. Data Collection: enhanced_dataset_creator.py

   • Scrapes Prothom Alo (English & Bengali)
   • Processes and cleans text
   • Creates train/validation/test splits

2. Model Training: model_trainer.py

   • Fine-tunes DistilGPT2 on Prothom Alo content
   • Uses appropriate hyperparameters for small dataset
   • Implements gradient checkpointing for memory efficiency

3. Model Conversion:

   • Converts to Safetensors format
   • Handles shared tensor issues
   • Creates comprehensive model card

4. Model Testing: test_model.py

   • Tests text generation capabilities
   • Validates Safetensors loading
   • Demonstrates model behavior
