WSL2安装CUDA记录

❗建议直接Windows安装驱动，不要在子系统里装

1. 官网安装，选择自己的版本即可

   https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&Distribution=Ubuntu&target_version=22.04&target_type=deb_local

   wget <https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-ubuntu2204.pin>
   sudo mv cuda-ubuntu2204.pin /etc/apt/preferences.d/cuda-repository-pin-600
   wget <https://developer.download.nvidia.com/compute/cuda/12.2.0/local_installers/cuda-repo-ubuntu2204-12-2-local_12.2.0-535.54.03-1_amd64.deb>
   sudo dpkg -i cuda-repo-ubuntu2204-12-2-local_12.2.0-535.54.03-1_amd64.deb
   sudo cp /var/cuda-repo-ubuntu2204-12-2-local/cuda-*-keyring.gpg /usr/share/keyrings/
   sudo apt-get updatesudo apt-get -y install cuda

2. 查看nvcc发现没有，但/usr/local/cuda/bin下是有nvcc的

   root@DESKTOP-PO8BKKM:~# nvcc --version
   Command 'nvcc' not found, but can be installed with:
   apt install nvidia-cuda-toolkit

   所以需要添加一下环境变量，就可以了。

   root@DESKTOP-PO8BKKM:~# export PATH=$PATH:/usr/local/cuda/bin
   root@DESKTOP-PO8BKKM:~# nvcc --version
   nvcc: NVIDIA (R) Cuda compiler driver
   Copyright (c) 2005-2023 NVIDIA Corporation
   Built on Tue_Jun_13_19:16:58_PDT_2023
   Cuda compilation tools, release 12.2, V12.2.91
   Build cuda_12.2.r12.2/compiler.32965470_0

3. nvidia-smi报错

   root@DESKTOP-PO8BKKM:~# nvidia-smi
   NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

   没有解决。。

   看一下nvidia版本

   root@DESKTOP-PO8BKKM:~# ls /usr/src | grep nvidia
   nvidia-535.54.03

   root@DESKTOP-PO8BKKM:~# sudo apt-get install dkms
   Reading package lists... Done

   dkms is already the newest version (2.8.7-2ubuntu2.2).

   root@DESKTOP-PO8BKKM:~# sudo dkms install -m nvidia -v 535.54.03
   Error! Your kernel headers for kernel 5.10.16.3-microsoft-standard-WSL2 cannot be found.
   Please install the linux-headers-5.10.16.3-microsoft-standard-WSL2 package or use the --kernelsourcedir option to tell DKMS where it's located.

4. 卸载试试看

   参考：http://www.manongjc.com/detail/62-afswonvqlgmvots.html

   sudo apt-get purge nvidia*
   sudo apt-get autoremove
   sudo apt-get autoclean
   sudo rm -rf /usr/local/cuda*

5. 尝试重新装一个wls-ubuntu版本cuda

   wget <https://developer.download.nvidia.com/compute/cuda/repos/wsl-ubuntu/x86_64/cuda-wsl-ubuntu.pin>
   sudo mv cuda-wsl-ubuntu.pin /etc/apt/preferences.d/cuda-repository-pin-600
   wget <https://developer.download.nvidia.com/compute/cuda/12.2.0/local_installers/cuda-repo-wsl-ubuntu-12-2-local_12.2.0-1_amd64.deb>
   sudo dpkg -i cuda-repo-wsl-ubuntu-12-2-local_12.2.0-1_amd64.deb
   sudo cp /var/cuda-repo-wsl-ubuntu-12-2-local/cuda-*-keyring.gpg /usr/share/keyrings/
   sudo apt-get update
   sudo apt-get -y install cuda

   依然没有用，哈哈

6. 尝试直接windows安装，成功。。
