AutoGPTQ/examples

Examples

To run example scripts in this folder, one must first install auto_gptq as described in this

Quantization

Commands in this chapter should be run under quantization folder.

Basic Usage

To Execute basic_usage.py, using command like this:

python basic_usage.py

To Execute basic_usage_with_wikitext2.py, using command like this:

python basic_usage_with_wikitext2.py

Note: There is about 0.6 ppl degrade on opt-125m model using AutoGPTQ, compared to GPTQ-for-LLaMa.

Quantize with Alpaca

To Execute quant_with_alpaca.py, using command like this:

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

Use --help flag to see detailed descriptions for more command arguments.

The alpaca dataset used in here is a cleaned version provided by gururise in AlpacaDataCleaned

Evaluation

Commands in this chapter should be run under evaluation folder.

Language Modeling Task

run_language_modeling_task.py script gives an example of using LanguageModelingTask to evaluate model's performance on language modeling task before and after quantization using tatsu-lab/alpaca dataset.

To execute this script, using command like this:

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

Use --help flag to see detailed descriptions for more command arguments.

Sequence Classification Task

run_sequence_classification_task.py script gives an example of using SequenceClassificationTask to evaluate model's performance on sequence classification task before and after quantization using cardiffnlp/tweet_sentiment_multilingual dataset.

To execute this script, using command like this:

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

Use --help flag to see detailed descriptions for more command arguments.

Text Summarization Task

run_text_summarization_task.py script gives an example of using TextSummarizationTask to evaluate model's performance on text summarization task before and after quantization using samsum dataset.

To execute this script, using command like this:

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

Use --help flag to see detailed descriptions for more command arguments.

Push To Hub

Commands in this chapter should be run under push_to_hub folder.

You can upload and share your quantized model to Hugging Face Hub by using push_to_hub function.

push_quantized_model_to_hf_hub.py provide a simple example to upload quantized model, tokenizer and configs at once.

First, you need to login, run the following command in the virtual environment where Hugging Face Transformers is installed:

huggingface-cli login

Then run the script like this:

python push_quantized_model_to_hf_hub.py --quantized_model_dir PATH/TO/QUANTIZED/MODEL/DIR --tokenizer_dir PATH/TO/TOKENIZER/DIR --repo_id REPO/ID

Use --help flag to see detailed descriptions for more command arguments.
