Ubuntu-显卡驱动-nvidia-smi报错：couldn‘t communicate with the NVIDIA driver

输入nvidia-smi之后，报错全部内容：

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver.

Make sure that the latest NVIDIA driver is installed and running

解决办法（最简单）：

sudo apt install dkms
sudo dkms install -m nvidia -v 418.87.00

reboot重启系统，nvidia-smi查看

其中，418.87.00 是之前成功安装的nvidia 驱动的版本号，你需要换成自己的。

可通过下面方法查到：

ls /usr/src | grep nvidia

遇到类似错误解决思路：

1. 可能是不经意间执行了sudo apt-get upgrade 升级了内核,导致内核和驱动不匹配，可以更换初始内核尝试，或者重装显卡驱动
2. Linux自动更新升级内核，可通过下面命令关闭：

        sudo gedit etc/apt/apt.conf.d/10periodic

        将所有值改为0
