Multiple Evaluation Tasks: Supports various tasks including language modeling, sequence classification, and text summarization.
Benchmarking Tools: Evaluate generation speed and model performance pre- and post-quantization.
PEFT Support: Integrate with Parameter-Efficient Fine-Tuning (PEFT) methods for enhanced model adaptability.

Installation

To get started with AutoGPTQ, follow these steps:

Clone the repository:

git clone https://github.com/PanQiWei/AutoGPTQ.git

Navigate to the project directory:
```
cd AutoGPTQ
```
Install the required dependencies:
```
pip install -r requirements.txt
```

Usage

AutoGPTQ provides a variety of scripts to facilitate model quantization and evaluation. Here are some examples:

Basic Usage

To execute the basic usage script, run:

python basic_usage.py

This script demonstrates how to download and upload quantized models from/to the 🤗 Hub.

Quantization with Alpaca

To quantize a model using the Alpaca dataset, use:

python quant_with_alpaca.py --pretrained_model_dir "facebook/opt-125m" --per_gpu_max_memory 4 --quant_batch_size 16

Evaluation Tasks

Evaluate model performance with:

CUDA_VISIBLE_DEVICES=0 python run_language_modeling_task.py --base_model_dir PATH/TO/BASE/MODEL/DIR --quantized_model_dir PATH/TO/QUANTIZED/MODEL/DIR

Replace PATH/TO/BASE/MODEL/DIR and PATH/TO/QUANTIZED/MODEL/DIR with your actual model paths.

Benefits

Integrating AutoGPTQ into your AI projects offers numerous advantages:

Enhanced Performance: Achieve faster inference times and reduced memory usage.
