ubuntu20文件安装和卸载cuda11.6

• 搜索cuda 11.6 nvidia，进入官网https://developer.nvidia.com/cuda-11-6-0-download-archive
  
• 选择linux --> runfile 用安装包安装
  

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
  

• 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
