安装最新版本的 `CUDA 10.1`：
# 卸载之前已经安装的cuda $ sudo apt-get remove nvidia-cuda-toolkit $ wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/cuda-ubuntu1804.pin $ sudo mv cuda-ubuntu1804.pin /etc/apt/preferences.d/cuda-repository-pin-600 $ wget http://developer.download.nvidia.com/compute/cuda/10.1/Prod/local_installers/cuda-repo-ubuntu1804-10-1-local-10.1.243-418.87.00_1.0-1_amd64.deb $ sudo dpkg -i cuda-repo-ubuntu1804-10-1-local-10.1.243-418.87.00_1.0-1_amd64.deb $ sudo apt-key add /var/cuda-repo-10-1-local-10.1.243-418.87.00/7fa2af80.pub $ sudo apt-get update $ sudo apt-get -y install cuda # 部分驱动可能会更新，需要执行更新，否则可能依旧不正常 $ sudo apt-get dist-upgrade $ sudo apt-get autoremove # 可能需要删除一下XWindow的配置文件，否则驱动可能不能正常加载 $ sudo rm -rf ~/.Xauthority # 如果出现如下错误 # ubuntu 18.04 "nvidia-340 导致 /usr/lib/x86_64-linux-gnu/libGL.so.1 # 转移到 /usr/lib/x86_64-linux-gnu/libGL.so.1.distrib" # 参考 http://www.mobibrw.com/?p=21739 # 删除安装源，可以节约几个GB的磁盘，安装完成后这部分已经用不上了 $ sudo apt-get remove --purge cuda-repo-ubuntu1804-10-1-local-10.1.243-418.87.00
