Nvidia-smi报错NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver.

断电或重启后，在linux下查看nvidia-smi报错：

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

可能的原因是，在ubuntu系统中系统内核升级了，导致新版本内核和原来显卡驱动不匹配

解决方法：

利用命令

ll /usr/src/

可查看下面有一个nvidia-4xx.xx/文件夹，记录这个驱动版本号，之后

sudo apt-get install dkms
sudo dkms install -m nvidia -v 4xx.xx（4xx.xx表示的是驱动版本号）
