麒麟银河操作系统下的英伟达驱动出现如下错误

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

出现连接不上NVIDIA驱动的情况，执行nvidia-smi，报错；重启服务器之后还是无法解决。

恢复方法：
step1: sudo yum install dkms

step2: ls /usr/src|grep nvidia （查询驱动版本号）
nvidia-410.48

step3: sudo dkms install -m nvidia -v 410.48

附：

lspci | grep -i nvidia  查询nvidia的显卡
