vllm 安装踩坑 (The NVIDIA driver on your system is too old)

我的环境如下：

• nvidia-smi 显示 cuda 版本是 11.7
• 目前最新vllm 要求的 torch 版本是 2.1.2，该版本要求的 cuda 版本是 11.8，所以不匹配。执行安装会遇到如下错误

RuntimeError: The NVIDIA driver on your system is too old (found version 11070). Please update your GPU driver by downloading and installing a new version from the URL: http://www.nvidia.com/Download/index.a
spx Alternatively, go to: https://pytorch.org to install a PyTorch version that has been compiled with your version of the CUDA driver.  

我尝试安装支持 cuda 11.7 的最新版本 torch==2.0.1，运行pip install -e .安装仍然会遇到上述问题。解决办法是修改 vllm 的安装配置文件：

• 1. requirements.txt

torch==2.1.2 改成 torch>=2.0.1
xformers == 0.0.23.post1 改成 xformers >= 0.0.022

因此你需要确保 xformers 版本是 0.0.022

• 2. requirements-build.txt

torch==2.1.2 改成 torch>=2.0.1

• 3. pyproject.toml

requires = [
    "ninja",
    "packaging",
    "setuptools >= 49.4.0",
    "torch == 2.1.2", 改成 "torch>=2.0.1"
    "wheel",
]
