We use the modelscope swift repository to perform GPTQ 4bit quantization. Quantization documentation can be found here. The quantization command is as follows:

bash

# Experimental Environment: A100
swift export \
    --quant_bits 4 \
    --model_type yi-1_5-6b-chat \
    --quant_method gptq \
    --dataset alpaca-zh alpaca-en sharegpt-gpt4-mini \
    --quant_seqlen 4096

Inference:

CUDA_VISIBLE_DEVICES=0 swift infer --model_type yi-1_5-6b-chat-gptq-int4

SFT:

CUDA_VISIBLE_DEVICES=0 swift sft --model_type yi-1_5-6b-chat-gptq-int4 --dataset leetcode-python-en

Original Model:

YI1.5-6B-Chat
