Ubuntu Server 20.04 系统安装（四）：深度学习 GPU 环境配置（CUDA12.2驱动+CUDA Toolkit 12.2+cuDNN v8.9.7）

引言

本文以 Ubuntu 20.04 操作系统为例，演示如何配置深度学习 GPU 环境。

一、NVIDIA 显卡驱动的安装

访问如下网址

https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&Distribution=Ubuntu&target_version=20.04&target_type=runfile_local

在这里插入图片描述

下载推荐的cuda并安装

复制箭头所指处的命令到命令行

wget https://developer.download.nvidia.com/compute/cuda/12.2.0/local_installers/cuda_12.2.0_535.54.03_linux.run

必须先关图形界面（重要）

如果不关，运行下面安装的命令之后会报错，装不上

systemctl isolate multi-user.target

关闭图形界面之后会重启，输入如下命令

安装驱动

sudo sh cuda_12.2.0_535.54.03_linux.run

稍等一会
在弹出的安装界面中选“continue”，如果选了会跳出安装，就说明安装失败，给了失败日志的路径，自己查看原因，一般是gcc版本问题，

gcc降级

sudo apt-get install gcc-7 g++-7
 
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 1
 
sudo update-alternatives --display gcc     //查看默认版本
 
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-7 9
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-9 1
 
sudo update-alternatives --display g++

如果没问题继续安装：

在这里插入图片描述

cuda安装包是自带显卡驱动的，所以这一步按空格去掉安装显卡驱动的选项，然后选择install

在这里插入图片描述

开启图形界面

sudo systemctl start graphical.target

二、安装 CUDA Toolkit 12.2

准备

开始安装之前，需要修改 apt-get 的镜像源，不然国内下载速度很慢。我们这里以阿里源为例演示如何修改。

备份官方源

sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak

安装vim：

sudo apt-get install vim

运行 sudo vim /etc/apt/sources.list 打开文件，并按 i 插入以下内容，按 ESC 后再按 :wq 保存退出

sudo vim /etc/apt/sources.list

deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse

# deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
# deb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse

更新数据源列表

sudo apt-get update

安装参考 NVIDIA 官网提供的教程。

Quick Start Guide 12.3 documentation

wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/cuda-ubuntu2004.pin
sudo mv cuda-ubuntu2004.pin /etc/apt/preferences.d/cuda-repository-pin-600
wget https://developer.download.nvidia.com/compute/cuda/12.3.1/local_installers/cuda-repo-ubuntu2004-12-3-local_12.3.1-545.23.08-1_amd64.deb
sudo dpkg -i cuda-repo-ubuntu2004-12-3-local_12.3.1-545.23.08-1_amd64.deb
sudo cp /var/cuda-repo-ubuntu2004-12-3-local/cuda-*-keyring.gpg /usr/share/keyrings/
sudo apt-get update
sudo apt-get -y install cuda-toolkit-12-3

sudo reboot # 非必需

执行完上述安装操作后，需要配置环境变量，让该系统下的所有用户都能使用：

打开全局配置文件

sudo vi /etc/profile

在文件末尾添加如下内容后保存退出。

export PATH=/usr/local/cuda-12.3/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-12.3/lib64\${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

激活环境变量

source /etc/profile

运行 nvcc -V 来校验安装是否成功，若正确显示版本号则说明安装成功

$ nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2023 NVIDIA Corporation
Built on Fri_Nov__3_17:16:49_PDT_2023
Cuda compilation tools,release 12.3,V12.3.103
Build cuda_12.3.r12.3/compiler.33492891_0

二、安装 cuDNN v8.9.7

安装参考 NVIDIA 官方提供的教程。

从官网下载合适版本的离线安装包

2. 开始安装

sudo dpkg -i cudnn-local-repo-ubuntu2004-8.9.7.29_1.0-1_amd64.deb
sudo cp /var/cudnn-local-repo-ubuntu2004-8.9.7.29/cudnn-local-30472A84-keyring.gpg /usr/share/keyrings/
cd /var/cudnn-local-repo-ubuntu2004-8.9.7.29/
sudo dpkg -i libcudnn8_8.9.7.29-1+cuda12.2_amd64.deb
sudo dpkg -i libcudnn8-dev_8.9.7.29-1+cuda12.2_amd64.deb
sudo dpkg -i libcudnn8-samples_8.9.7.29-1+cuda12.2_amd64.deb

校验安装是否成功（最终输出 Test passed! 则说明安装成功）

cp -r /usr/src/cudnn_samples_v8/ $HOME
cd  $HOME/cudnn_samples_v8/mnistCUDNN
make clean && make
./mnistCUDNN

校验安装时如果遇到下述错误：

```bash
test.c:1:10: fatal error: FreeImage.h: No such file or directory
    1 | #include "FreeImage.h"
      |          ^~~~~~~~~~~~~
compilation terminated.
>>> WARNING - FreeImage is not set up correctly. Please ensure FreeImage is set up correctly. <<<

可通过如下方式解决，然后重新进行校验

sudo apt-get -y install  libfreeimage3 libfreeimage-dev

重启后验证通过

sudo reboot

验证通过：

GPUstat

这是一个可以替换 nvidia-smi 查看显卡信息的一个工具。可以非常清楚地看到各个显卡的温度、利用率、正在使用的用户以及各用户占用的显存等。

在这里插入图片描述

使用如下命令安装：

sudo apt install python3-pip
sudo pip install gpustat

用法非常简单，记住下面这一条命令就行：

gpustat -i

NetSM

这是一个跨平台的命令行网速监测工具，可以看到服务器实时网速显示。

在这里插入图片描述

通过如下命令安装：

sudo apt install python3-pip
sudo pip install netsm

用法非常简单，记住下面这一条命令就行：

netsm show

Tmux

跑耗时较长的任务时，可以打开 tmux 将任务挂起，即使你关闭了窗口，任务仍然在后台运行。

sudo apt-get install tmux

Axel

区别于 wget 单线程下载的多线程下载工具。用法很简单，通过 -n 参数指定线程数即可，例如：axel -n 10 下载链接。

sudo apt-get install axel

提示

上述配置了三个深度学习 GPU 环境，分别是 PyTorch，TensorFlow 2 和 TensorFlow 1。且都是通过管理员来配置的。其他普通用户使用时，仅需使用 conda 在新建环境时克隆即可，下面给一个例子。

例如，普通用户要使用 PyTorch 环境，但他同时还需要安装 requests 包，直接在名为 pytorch 的环境里面是没有办法安装，因为缺少写入权限。因此可以通过如下克隆的方式安装：

conda create -n pytorch2 --clone pytorch
conda activate pytorch2
pip install requests

这样既节省了服务器的存储空间，又避免了重复安装环境的烦恼。

当然你不克隆，直接激活使用也是可以的：

conda activate pytorch
pip install requests

因为默认会安装 requests 到用户家目录下，不会和其他用户的环境产生冲突。但如果环境多了，就不太容易区分了。
