- ## docker 环境里面 nvidia-smi 能看到显卡也能跑 cuda 却不能跑 vulkan

因为这个docker环境的nvidia驱动没有安装opengl/vulkan支持

首先运行 nvidia-smi 查看当前驱动版本

```
NVIDIA-SMI 535.161.07
Driver Version: 535.161.07
CUDA Version: 12.2
```

然后去下载对应版本的NVIDIA驱动，安装用户态驱动文件，跳过内核部分

```
wget https://us.download.nvidia.com/tesla/535.161.07/NVIDIA-Linux-x86_64-535.161.07.run
chmod +x NVIDIA-Linux-x86_64-535.161.07.run
./NVIDIA-Linux-x86_64-535.161.07.run --silent --no-kernel-module
```

安装时会报一些文件权限错误，不用管，安装完成后 vulkan 支持就可用了。最后安装 vulkaninfo 查看gpu信息

```
dnf install vulkan-tools
vulkaninfo
```
