１、NVidia显示驱动安装:

https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html

GPU显示驱动安装:

    在docker终端输入ubuntu-drivers devices，查看显卡配置信息，正常显示如下：

　root@e25881d8e29d:/# ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
modalias : pci:v000010DEd00001F36sv0000103Csd0000860Fbc03sc00i00
vendor   : NVIDIA Corporation
driver   : nvidia-driver-450-server - distro non-free
driver   : nvidia-driver-440-server - distro non-free
driver   : nvidia-driver-460 - distro non-free recommended
driver   : nvidia-driver-450 - distro non-free
driver   : nvidia-driver-418-server - distro non-free
driver   : xserver-xorg-video-nouveau - distro free builtin

== /sys/devices/pci0000:00/0000:00:1d.5/0000:70:00.0 ==
modalias : pci:v00008086d00002723sv00008086sd00000088bc02sc80i00
vendor   : Intel Corporation
driver   : backport-iwlwifi-dkms - distro free

如果提示bash: ubutnu-drivers: command not found，则安装：sudo apt-get install ubuntu-drivers-common

安装显卡驱动：


 sudo ./NVIDIA-Linux-x86_64-460.39.run -no-x-check -no-nouveau-check -no-opengl-files //只有禁用opengl这样安装才不会出现循环登陆的问题　Ubuntu 16.04安装NVIDIA驱动后导致的循环登录问题

-no-x-check：安装驱动时关闭X服务

-no-nouveau-check：安装驱动时禁用nouveau

-no-opengl-files：只安装驱动文件，不安装OpenGL文件

或者

sudo apt-get install nvidia-driver-460   (460.32)


查看驱动版本：cat /proc/driver/nvidia/version

root@e25881d8e29d:/workspace# cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX x86_64 Kernel Module  450.102.04  Tue Dec 29 06:51:23 UTC 2020
GCC version:  gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04)

卸载GPU驱动:

sudo apt-get purge nvidia*

sudo add-apt-repository ppa:graphics-drivers

sudo apt-get update

sudo apt-get install nvidia-415 nvidia-settings nvidia-prime

nvidia-smi

2、Cuda安装

　　ls /dev/nvidia*，显示如下：

/dev/nvidia-modeset  /dev/nvidia-uvm  /dev/nvidia-uvm-tools  /dev/nvidia0  /dev/nvidiactl
/dev/nvidia-caps:
nvidia-cap1  nvidia-cap2

CUDA版本下载链接：https://developer.download.nvidia.cn/compute/cuda/repos/ubuntu1804/x86_64/

先下载与显卡驱动版本对应的CUDA包:

 dpkg -i cuda-repo-ubuntu1804-11-2-local_11.2.1-460.32.03-1_amd64.deb,存入当前目录

#install CUDA
sudo dpkg -i sudo dpkg -i cuda-repo-ubuntu1804-11-2-local_11.2.1-460.32.03-1_amd64.deb
sudo apt-key add /var/cuda-repo-ubuntu1804-11-2-local/7fa2af80.pub
sudo apt-get update
sudo apt-get -y install cuda

安装完之后，需要设置环境变量

sudo gedit ~/.bashrc
export LD_LIBRARY_PATH=/usr/local/cuda/lib

export PATH=$PATH:/usr/local/cuda/bin

然后，输入以下命令使配置的环境变量立即生效：

source ~/.bashrc

查看当前cuda是否成功安装

nvcc -V 　


root@e25881d8e29d:/usr/local/cuda-10.2/lib64# nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2019 NVIDIA Corporation
Built on Wed_Oct_23_19:24:38_PDT_2019
Cuda compilation tools, release 10.2, V10.2.89

出现以上信息，说明cuda10.2即已安装完成。
３．CUDNN安装
 先下载好包libcudnn8_8.1.0.77-1+cuda11.2_amd64.deb要本地目录
　sudo dpkg -i libcudnn8_8.1.0.77-1+cuda11.2_amd64.deb

碰到一个问题：先安装好GPU显卡，然后再装CUDA,CUDNN,重启下显卡驱动直接掉了，需要再次安装GPU显卡，nvidia-smi显示４６０．３９，一切正常！
