Green-Bit-LLM

A toolkit for fine-tuning, inferencing, and evaluating GreenBitAI's low-bit LLMs.

Introduction

This Python package uses the Bitorch Engine for efficient operations on GreenBitAI's Low-bit Language Models (LLMs). It enables high-performance inference on both cloud-based and consumer-level GPUs, and supports full-parameter fine-tuning directly using quantized LLMs. Additionally, you can use our provided evaluation tools to validate the model's performance on mainstream benchmark datasets.

News

• [2024/10]
  • Langchain integration, various refactoring and improvements.
• [2024/04]
  • We have launched over 200 low-bit LLMs in GreenBitAI's Hugging Face Model Zoo. Our release includes highly precise 2.2/2.5/3-bit models across the LLM family, featuring LLaMA 2/3, 01-Yi, Qwen, Mistral, Phi-3, Gemma, and more.
  • We released Bitorch Engine for low-bit quantized neural network operations. Our release support full parameter fine-tuning and parameter efficiency fine-tuning (PEFT), even under extremely constrained GPU resource conditions.
  • We released gbx-lm python package which enables the efficient execution of GreenBitAI's low-bit models on Apple devices with MLX.

LLMs

We have released over 200 highly precise 2.2/2.5/3/4-bit models across the modern LLM family, featuring LLaMA 2/3, 01-Yi, Qwen, Mistral, Phi-3, and more.

In addition to our low-bit models, green-bit-llm is fully compatible with the AutoGPTQ series of 4-bit quantization and compression models.

Installation

We support several ways to install this package. Except for the docker method, you should first install Bitorch Engine according to the official instructions.

Then choose how you want to install it:

Using Pip

pip install green-bit-llm

From source

Clone the repository and install the required dependencies (for Python >= 3.9):

git clone https://github.com/GreenBitAI/green-bit-llm.git
pip install -r requirements.txt

Afterward, install Flash Attention (flash-attn) according to their official instructions.

Conda

Alternatively, you can also use the prepared conda environment configuration:

conda env create -f environment.yml
conda activate gbai_cuda_lm

Afterward, install Flash Attention (flash-attn) according to their official instructions.

Alternatively you can activate an existing conda environment and install the requirements with pip (as shown in the previous section).

Docker

To use docker, you can also use the provided Dockerfile which extends the bitorch-engine docker image. Build the bitorch-engine image first, then run the following commands:

cd docker
cp -f ../requirements.txt .
docker build -t gbai/green-bit-llm .
docker run -it --rm --gpus all gbai/green-bit-llm

Check the docker readme for options and more details.

Requirements

• Python 3.x
• Bitorch Engine
• See requirements.txt or environment.yml for a complete list of dependencies

Examples

Simple Generation

Run the simple generation script as follows:

CUDA_VISIBLE_DEVICES=0 python -m green_bit_llm.inference.sim_gen --model GreenBitAI/Qwen-1.5-1.8B-layer-mix-bpw-3.0 --max-tokens 100 --use-flash-attention-2 --ignore-chat-template

PPL Evaluation

CUDA_VISIBLE_DEVICES=0 python -m green_bit_llm.evaluation.evaluate --model GreenBitAI/Qwen-1.5-4B-layer-mix-bpw-3.0 --trust-remote-code --eval-ppl --ppl-tasks wikitext2,c4_new,ptb

Full-parameter fine-tuning

Run the script as follows to fine-tune the quantized weights of the model on the target dataset. The '--tune-qweight-only' parameter determines whether to fine-tune only the quantized weights or all weights, including non-quantized ones.

CUDA_VISIBLE_DEVICES=0 python -m green_bit_llm.sft.finetune --model GreenBitAI/Qwen-1.5-1.8B-layer-mix-bpw-3.0 --dataset tatsu-lab/alpaca --optimizer DiodeMix --tune-qweight-only

# AutoGPTQ model Q-SFT
CUDA_VISIBLE_DEVICES=0 python -m green_bit_llm.sft.finetune --model astronomer/Llama-3-8B-Instruct-GPTQ-4-Bit --dataset tatsu-lab/alpaca --tune-qweight-only --batch-size 1

Parameter efficient fine-tuning

CUDA_VISIBLE_DEVICES=0 python -m green_bit_llm.sft.peft_lora --model GreenBitAI/Qwen-1.5-1.8B-layer-mix-bpw-3.0 --dataset tatsu-lab/alpaca --lr-fp 1e-6

# AutoGPTQ model with Lora
CUDA_VISIBLE_DEVICES=0 python -m green_bit_llm.sft.peft_lora --model astronomer/Llama-3-8B-Instruct-GPTQ-4-Bit --dataset tatsu-lab/alpaca --lr-fp 1e-6
