下载GPU驱动包
驱动下载：https://www.nvidia.com/Download/Find.aspx
复制好地址后，使用wget命令下载。
[root@node ~]# wget https://us.download.nvidia.com/tesla/450.191.01/NVIDIA-Linux-x86_64-450.191.01.run
[root@node ~]# ls
NVIDIA-Linux-x86_64-450.191.01.run
安装GPU驱动包
[root@node ~]# sh NVIDIA-Linux-x86_64-450.191.01.run
Verifying archive integrity... OK
Uncompressing NVIDIA Accelerated Graphics Driver for Linux-x86_64 450.191.01.....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
执行以上命令后，跳出交互界面，全部默认确定即可。
安装完后，进行验证，出现一下信息证明安装成功。

卸载GPU驱动包
/usr/bin/nvidia-uninstall
reboot
GPU驱动包安装排错
由于使用的测试机器已经有装相关包，所以是卸载后重新装的，但在卸载时没有完全卸载完所有东西，且未进行重启操作，导致上述安装时出现一些问题，报错截图如下：
报错文本：
ERROR: An NVIDIA kernel module ‘nvidia’ appears to already be loaded in your kernel. This may be because it is in use (for example, by an X server, a CUDA program, or the NVIDIA
Persistence Daemon), but this may also happen if your kernel was configured without support for module unloading. Please be sure to exit any programs that may be using the GPU(s)
before attempting to upgrade your driver. If no GPU-based programs are running, you know that your kernel supports module unloading, and you still receive this message, then an
error may have occured that has corrupted an NVIDIA kernel module’s usage count, for which the simplest remedy is to reboot your computer.
报错文本：
ERROR: Installation has failed. Please see the file ‘/var/log/nvidia-installer.log’ for details. You may find suggestions on fixing installation problems in the README available on the
Linux driver download page at www.nvidia.com.
大致是说已有相关程序在使用了nvidia的模块了，导致安装报错。
不是很明确是什么原因，所以优先考虑了日志，如下：

查看后没有得到有用的信息，但心里已经有了想法，于是开始排查使用nvidia的相关进程什么的。
[root@node ~]# ps -ef | grep nvidia
root 1569 2 0 11:06 ? 00:00:01 [irq/86-nvidia]
root 1570 2 0 11:06 ? 00:00:00 [nvidia]

[root@node ~]# kill -9 676
查到了，是某一个agent在使用，于是kill后重新安装，解决问题。
