Fine-Tuning Llama 3.2 3B Instruct for Python Code: A Comprehensive Guide with Unsloth

Fine-Tuning Llama 3.2 3B Instruct for Python Code This guide explains how to fine-tune the Llama 3.2 3B Instruct model using a Python code dataset. You'll learn to customize large language models for coding tasks and understand the tools needed for fine-tuning with Unsloth. To start, install the required libraries: Unsloth for fine-tuning, Transformers for pre-trained models, and xFormers for memory optimization. Import essential classes like FastLanguageModel for loading the model, SFTTrainer for training, and load_dataset for preparing your dataset. Load your Python code dataset with a maximum sequence length of 2048 tokens. Save it under your Hugging Face username for easy access. Load the model in a memory-efficient 4-bit format to handle longer text inputs while saving memory. Use Low-Rank Adaptation (LoRA) to enhance the model's performance and memory efficiency. Mount your Google Drive to save training outputs directly. Set up the training loop by creating a training instance, specifying parameters like batch size and learning rate, and starting the training process. After training, save your fine-tuned model and tokenizer for future use. In conclusion, this tutorial shows how to fine-tune the Llama 3.2 3B Instruct model for Python coding tasks. Using Unsloth improves memory usage, and Hugging Face tools simplify dataset handling.
