## About Quantization
我们使用modelscope [swift](https://github.com/modelscope/swift/)仓库进行GPTQ 4bit量化. 量化文档可以查看[这里](https://github.com/modelscope/swift/blob/main/docs/source/LLM/LLM%E9%87%8F%E5%8C%96%E6%96%87%E6%A1%A3.md). 量化命令如下:

We use the modelscope [swift](https://github.com/modelscope/swift/) repository to perform GPTQ 4bit quantization. Quantization documentation can be found [here](https://github.com/modelscope/swift/blob/main/docs/source_en/LLM/LLM-quantization.md). The quantization command is as follows:

```bash
# Experimental Environment: A100
swift export \
    --quant_bits 4 \
    --model_type yi-1_5-9b-chat \
    --quant_method gptq \
    --dataset alpaca-zh alpaca-en sharegpt-gpt4-mini \
    --quant_seqlen 4096
```

Inference:
```bash
CUDA_VISIBLE_DEVICES=0 swift infer --model_type yi-1_5-9b-chat-gptq-int4
```

SFT:
```bash
CUDA_VISIBLE_DEVICES=0 swift sft --model_type yi-1_5-9b-chat-gptq-int4 --dataset leetcode-python-en
```
