NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

安裝好驅動后，apt-get upgrade執行了一下。結果重啟驅動就不行了。

以為驅動壞了，卸載重裝也不頂事。最后找來找去這樣搞好了。

 

sudo apt install nvidia-cuda-toolkit

 

搞環境很瑣碎，是以為記。

 

重裝的步驟

 

1.卸載nvidia驅動
卸載NV驅動和安裝一樣，首先ctrl+Alt+F2進入命令行狀態，然后停止lightdm
sudo service lightdm stop
或者
sudo /etc/init.d/lightdm stop

卸載命令位置/usr/bin/nvidia-uninstall，以下命令即可卸載。
sudo /usr/bin/nvidia-uninstall
————————————————
然后重裝：

sudo ./cuda_10.0.130_410.48_linux.run

 

選 driver 和 nvidia X 這兩個。其他不選。

就安裝好了。
