# 🐍 Python Code-Only Qwen
**A fine-tuned model that generates ONLY executable Python code, with no explanations or conversations.**
## 🚀 Quick Inference Example
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
# Load model
model = AutoModelForCausalLM.from_pretrained("Mercy-62/python-code-only-Qwen-lora")
tokenizer = AutoTokenizer.from_pretrained("Mercy-62/python-code-only-Qwen-lora")
# Use exact same prompt format from training
alpaca_prompt = """Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.
### Instruction:
{}
### Input:
{}
### Response:
{}"""
# Enable faster inference (if using Unsloth)
# FastLanguageModel.for_inference(model)
# Test 1: Simple code generation
inputs = tokenizer(
[
alpaca_prompt.format(
"Write a Python function to reverse a string", # instruction
"", # input (leave empty if no context)
"", # output - leave blank for generation
)
],
return_tensors="pt"
).to("cuda")
outputs = model.generate(**inputs, max_new_tokens=128, use_cache=True)
print("Test 1 - Reverse string function:")
print(tokenizer.batch_decode(outputs)[0]) |
