搭徏llamafactory微调、评估、测试和量化环境

paulwong — Thu, 16 Jan 2025 08:54:00 GMT

0. 配置环境变量

HF_ENDPOINT=https://hf-mirror.com
HF_HOME=/root/autodl-tmp/paul/tools/huggingface

1. 本机安装python 3.10, �q�设�|��Y件源

pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
pip config set global.index-url https://mirrors.huaweicloud.com/repository/pypi/simple

2. 安装miniconda

https://juejin.cn/post/7078965942968909854

3. 新徏一个环�? �q�激�z?/div>

conda create -n quantization python=3.12

2. 本机安装pytorch2.5.1+cuda12.4

pip3 install torch torchvision torchaudio

pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu124

3. clone llamafactory源码

git clone https://github.com/hiyouga/LLaMA-Factory

4. llamafactory本地安装依赖

pip install -e .

pip install -e .["vllm","gptq"]

5. 启动webui

llamafactory-cli webui

6. 在页面中填入相关参数�q�行操作

VLLM量化推理

https://llmc-zhcn.readthedocs.io/en/latest/backend/vllm.html#id1

安装此工具前需安装两个�?

sudo apt-get install cmake
sudo apt-get install pkgconfig

配置huggingface镜像地址:

export HF_ENDPOINT=https://hf-mirror.com

下蝲代码�? �q�安装python依赖

git clone https://github.com/ModelTC/llmc.git
cd llmc/
pip install -r requirements.txt

扑ֈ�量化�Ҏ��的配�|�文�? �q�作修改
