Fine-tuning Flan-T5

This project aims to fine-tune the Flan-T5 language model using Hugging Face's Transformers library. By following these steps, you can fine-tune the model and use it for inference.

---

Prerequisites

Before getting started, make sure you have the following:

• Hugging Face API token (HF token)
• Python installed on your system
• CUDA-enabled GPU (for training)

---

Setup

1. Clone this repository to your local machine.

   git clone https://github.com/mltrev23/Fine-Tuning-LLaMA-2/

2. Install the required packages using the following command:

   pip install -r requirements.txt

Fine-tuning Flan-T5

There are four methods of fine-tuning available:

1. Additive Fine-Tuning: Adds layers to train.

   python additive-fine-tuning.py

2. Full Fine-Tuning: Trains all weights of the model.

   python full-fine-tuning.py

3. Selective Fine-Tuning: Chooses specific layers of the original model to train.

   python selective-fine-tuning.py

4. Template Fine-Tuning: Uses a predefined template for training. The template can be modified as needed.

---

Custom Data Ingestion

To ingest your own data for fine-tuning, modify the code in your scripts to load your dataset. Here’s an example of loading a text dataset:

from transformers import LineByLineTextDataset

dataset = LineByLineTextDataset(tokenizer=tokenizer, file_path='datasets/bittensor.txt', block_size=128)

---

Inference

To perform inference using the fine-tuned Flan-T5 model, you can use the following scripts:

1. Generate Using Forward Pass: This script demonstrates generating text using a forward pass approach.

   python generate-using-forward.py

2. Main Inference Script: This script provides a straightforward way to generate outputs from the model.

   python main.py

Example Inference

You can modify the input text in the main.py file to test the model:

input_text = ["What is FAANG?"]

This will generate an output based on the input provided.

Happy Fine-Tuning!

Feel free to modify the scripts as needed for your specific tasks and datasets. If you encounter any issues, check the Hugging Face documentation or seek help from the community.
