Q-Lora (experimental support)

This example demonstrates how to finetune a llama2-7b model use Big-LLM 4bit optimizations using Intel GPUs.

0. Requirements

To run this example with BigDL-LLM on Intel GPUs, we have some recommended requirements for your machine, please refer to here for more information.

Example: Finetune llama2-7b using qlora

This example is ported from bnb-4bit-training

1. Install

conda create -n llm python=3.9
conda activate llm
# below command will install intel_extension_for_pytorch==2.0.110+xpu as default
# you can install specific ipex/torch version for your need
pip install --pre --upgrade bigdl-llm[xpu] -f https://developer.intel.com/ipex-whl-stable-xpu
pip install git+https://github.com/huggingface/transformers.git@95fe0f5
pip install peft==0.5.0

2. Configures OneAPI environment variables

source /opt/intel/oneapi/setvars.sh

3. Run

python ./qlora_finetuning.py --repo-id-or-model-path REPO_ID_OR_MODEL_PATH
