ubuntu20文件安装和卸载cuda11.6

wget https://developer.download.nvidia.com/compute/cuda/11.6.0/local_installers/cuda_11.6.0_510.39.01_linux.run
sudo sh cuda_11.6.0_510.39.01_linux.run

• 选择continue

  

• 输入accept

  

• 按空格取消第一个对driver的勾选（看别人也是这么做得）

  

• 覆盖symlink，先选择yes，以后再了解

  

• 然后给你一个summary

  

  Please make sure that

  • PATH includes /usr/local/cuda-11.6/bin
  • LD_LIBRARY_PATH includes /usr/local/cuda-11.6/lib64, or, add /usr/local/cuda-11.6/lib64 to /etc/ld.so.conf and run ldconfig as root
    • 配置环境变量，实际安装在/usr/local/cuda-11.6但是会在/usr/local/cuda/建立软链接（应该是叫这个）所以cuda后不带数字后缀也是可以的

      export PATH=/usr/local/cuda/bin${PATH:+:${PATH}}
      export LD_LIBRARY_PATH=/usr/local/cuda/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
      export CUDA_HOME=/usr/local/cuda
      

      • 检测是否安装成功 nvcc -V

        • 如何卸载cuda，使用/usr/local/cuda-11.6/bin/cuda-uninstaller卸载得干干净净

          cd /usr/local/cuda-11.6/bin
          sudo ./cuda-uninstaller
