4.15.0-142-generic
问题描述：
服务器使用nvidia-smi突然显卡报错：
nvidia-smi
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
解决方案：
1.查看服务器nvidia版本
ls /usr/src | grep nvidia
nvidia-455.23.05
2.执行apt install dkms
apt install dkms
Reading package lists... Done
Building dependency tree
Reading state information... Done
dkms is already the newest version (2.2.0.3-2ubuntu11.8).
0 upgraded, 0 newly installed, 0 to remove and 62 not upgraded.
3.执行dkms install -m nvidia -v 455.23.05（你的显卡版本号）
dkms install -m nvidia -v 455.23.05
Creating symlink /var/lib/dkms/nvidia/455.23.05/source ->
