Model Information
Quantized version of EleutherAI/pythia-12b using torch.float32 for quantization tuning.
- 4 bits (INT4)
- group size = 128
- Asymmetrical Quantization
- Method AutoRound (WOQ)
Fast and low memory, 2-3X speedup (slight accuracy drop at W4G128)
Quantization framework: Intel AutoRound
Note: this INT4 version of pythia-12b has been quantized to run inference through CPU.
Replication Recipe
Step 1 Install Requirements
I suggest to install requirements into a dedicated python-virtualenv or a conda enviroment.
python -m pip install <package> --upgrade
- accelerate==1.0.1
- auto_gptq==0.7.1
- neural_compressor==3.1
- torch==2.3.0+cpu
- torchaudio==2.5.0+cpu
- torchvision==0.18.0+cpu
- transformers==4.45.2
Step 2 Build Intel Autoround wheel from sources
python -m pip install git+https://github.com/intel/auto-round.git
Step 3 Script for Quantization
from transformers import AutoModelForCausalLM, AutoTokenizer
model_name = "EleutherAI/pythia-12b"
model = AutoModelForCausalLM.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)
from auto_round import AutoRound
bits, group_size, sym = 4, 128, False
autoround = AutoRound(model, tokenizer, nsamples=128, iters=200, seqlen=512, batch_size=4, bits=bits, group_size=group_size, sym=sym)
autoround.quantize()
output_dir = "./AutoRound/EleutherAI_pythia-12b-autoround-int4-gs128-asym"
autoround.save_quantized(output_dir, format='auto_round', inplace=True)
