~$ 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.

查看驱动信息

~$ dpkg -l | grep nvidia 
ii  nvidia-modprobe     384.103-0ubuntu1     amd64     Load the NVIDIA kernel driver and create device files

看到左上角直接是cuda9.2，点击1.7GB的下载，下载的文件名字是cuda_9.2.88_396.26_linux.run，其中396.26是指你的驱动版本必须要比这个低，但也不能太低。安装其他版本也一样。

answer

I wouldn't disregard it. Ubuntu's driver packages don't interact well with the .run installer. I'd recommend either finding an Ubuntu package with the driver version you need, or uninstalling all of the Ubuntu NVIDIA driver packages before installing the .run package.

试试使用deb安装8.0版本；

https://developer.nvidia.com/cuda-80-ga2-download-archive；

Installation Instructions:

    `sudo dpkg -i cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.deb`
    `sudo apt-get update`
    `sudo apt-get install cuda`

最后尝试了网上几乎所有方法，还是没有成功，没办法只能重装系统，然后就可以查询到nvidia-smi的结果。

可能最开始装系统的时候有问题吧。
