A complete guide to fine-tuning Code Llama

Sep 04, 2023 - ragntune.com
This guide provides a step-by-step tutorial on how to fine-tune Code Llama, a coding model, to become a proficient SQL developer. The author uses the b-mc2/sql-create-context, a collection of text queries and their corresponding SQL queries, and applies a Lora approach, which involves quantizing the base model to int 8, freezing its weights, and only training an adapter. The guide covers various steps including pip installations, loading libraries, loading the dataset, loading the model, checking the base model, tokenization, setting up Lora, and training.

The guide also provides instructions on how to check the model's performance, set up tokenization settings, and prepare the model for int8 training. The author uses a variety of libraries and tools such as Python 3.10, cuda 11.8, Huggingface Hub, and Weights and Biases to execute the process. The guide concludes with the loading of the final checkpoint and testing the model's output, which proves successful. The author suggests following another guide to convert the adapter to a Llama.cpp model for local execution.

Key takeaways:

  • The guide provides a detailed process of fine-tuning Code Llama to enhance its performance as an SQL developer, using a specific dataset and a Lora approach.
  • The process involves several steps including pip installs, loading libraries, loading the dataset, loading the model, checking the base model, tokenization, setting up Lora, and training.
  • The guide also provides code snippets for each step, making it easier for users to follow along and implement the process.
  • After training, the model is tested to verify its performance. The guide concludes that the fine-tuned model works effectively, providing the correct SQL query output.
