NVIDIA-SMI has failed because it couldn‘t communicate with the NVIDIA driver.

电脑跑着程序，之后莫名关机了，开机后用nvidia-smi查看显卡状态信息报错

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

可以按照以下方式解决

# 查看自己之前安装的驱动版本
ls /usr/src | grep nvidia

比如我的是nvidia-470.86

# 输入以下命令即可解决
sudo apt-get install dkms
sudo dkms install -m nvidia -v 470.86
