本文主要是介绍【已解决】ubuntu nividia-smi 出现“Make sure that the latest NVIDIA driver is installed and running.”，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
有个小朋友不知更新了啥导致服务器输入nvidia-smi之后显示如下信息：NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
此问题我找了半天原因，不管怎么重装nvidia驱动都不对，最后有用的解决方案是更新内核。

解决方案：更新Ubuntu内核（我们服务器从Linux 3.13.0-24-generic更新至Linux 4.12.9-041209-generic），然后按照正常流程安装最新的驱动nvidia-390
具体操作如下
#系统内核更新
#下载3个内核deb安装文件
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12.9/linux-headers-4.12.9-041209_4.12.9-041209.201708242344_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12.9/linux-headers-4.12.9-041209-generic_4.12.9-041209.201708242344_amd64.deb
