• Fine-Tuning Llama2-7b (Ludwig) for Code Generation

Goal

The goal of this project is to fine-tune the Llama2-7b language model for code generation using the QLORA method. The model will take natural language as input, and should return code as output. We're first going to iterate on a base Llama-2-7b model with prompting, and finally instruction-fine-tune the model.

As an example, if we prompt the model with this instruction:

Instruction: Create an array of length 5 which contains all even numbers between 1 and 10.

We want the model to produce exactly this response:

Response: array = [2, 4, 6, 8, 10]

QLORA Method for Fine-Tuning

The QLORA method for fine-tuning large language models (LLMs) is a parameter-efficient approach that uses 4-bit quantization to reduce the memory and computational requirements of fine-tuning. QLORA is implemented in the PEFT library, which is built on top of the Hugging Face Transformers library.

Ludwig Data Format

Ludwig requires data to be in a specific format. The main components of the data format are:

• input_features: Defines the input features of the model. Each feature must have a name and type.
• output_features: Defines the output features of the model. Similar to input features, each output feature must have a name and type.

Here is an example of a simple Ludwig config:

input_features:
  - name: instruction
    type: text
output_features:
  - name: output
    type: text

This config tells Ludwig to use the column called instruction in the dataset as an input feature and the output column as an output feature.
