nvidia-smi: Failed to initialize

1、先尝试重启电脑，一般可以解决

2、如果是内核和驱动版本不一致

cat /proc/driver/nvidia/version

-->
NVRM version: NVIDIA UNIX x86_64 Kernel Module  430.34  Wed Jun 26 12:19:48 CDT 2019
GCC version:  gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.12)

内核版本 Kernel Module 为 430.34， 系统内核 16.04.12

然后卸载现有驱动

sudo apt-get purge nvidia*

终端输入,把显卡驱动加入ppa（个人软件包文档，仅支持Ubuntu），类似于应用商店

sudo add-apt-repository ppa:graphics-drivers
sudo apt-get update

最后重新安装驱动，需要将“430”替换成刚才查到的版本号：

sudo apt-get install nvidia-driver-430 nvidia-settings nvidia-prime
