在Ubuntu上安装CUDA和cuDNN以及验证安装步骤

本教程详细介绍了如何在Ubuntu操作系统上安装CUDA（NVIDIA的并行计算平台）和cuDNN（深度神经网络库），以及如何验证安装是否成功。通过按照这些步骤操作，您将能够配置您的系统以利用GPU加速深度学习和其他计算密集型任务。此外，还包括如何设置环境变量和编译运行示例代码以验证CUDA和cuDNN的正常运行。

安装 CUDA
通过网络仓库安装CUDA（适用于Ubuntu）
配置环境变量
验证安装
安装 cuDNN
验证 cuDNN

安装 CUDA

在安装CUDA之前，我们需要进行一些预安装操作。首先，您需要安装当前正在运行的内核的头文件和开发包。打开终端并执行以下命令：

sudo apt-get install linux-headers-$(uname -r)

接下来，您需要删除过时的签名密钥：

sudo apt-key del 7fa2af80

通过网络仓库安装CUDA（适用于Ubuntu）

新的CUDA存储库的GPG公钥是3bf863cc。您可以通过cuda-keyring包或手动方法将其添加到系统中，不建议使用apt-key命令。执行以下步骤：

安装新的cuda-keyring包。根据您的系统版本替换$distro/$arch：

wget https://developer.download.nvidia.com/compute/cuda/repos/$distro/$arch/cuda-keyring_1.1-1_all.deb
sudo dpkg -i cuda-keyring_1.1-1_all.deb

$distro/$arch 应该根据以下选项之一进行替换：

ubuntu1604/x86_64：适用于 Ubuntu 16.04 64位版本。
ubuntu1804/cross-linux-sbsa：适用于 Ubuntu 18.04 交叉编译版本（SBSA 架构）。
ubuntu1804/ppc64el：适用于 Ubuntu 18.04 64位 PowerPC 架构版本。
* ubuntu1804/sbsa：适用于 Ubuntu 18.04 SBSA 架构版本。
ubuntu1804/x86_64：适用于 Ubuntu 18.04 64位版本。
ubuntu2004/cross-linux-aarch64：适用于 Ubuntu 20.04 交叉编译版本（AArch64 架构）。
ubuntu2004/arm64：适用于 Ubuntu 20.04 64位 ARM 架构版本。
ubuntu2004/cross-linux-sbsa：适用于 Ubuntu 20.04 交叉编译版本（SBSA 架构）。
ubuntu2004/sbsa：适用于 Ubuntu 20.04 SBSA 架构版本。
ubuntu2004/x86_64：适用于 Ubuntu 20.04 64位版本。
ubuntu2204/sbsa：适用于 Ubuntu 22.04 SBSA 架构版本。
ubuntu2204/x86_64：适用于 Ubuntu 22.04 64位版本。
根据您的Ubuntu版本和架构选择适当的替代项来执行相应的安装步骤。

更新Apt仓库缓存：

sudo apt-get update

安装 CUDA SDK:
您可以使用以下命令获取可用的CUDA包列表：

cat /var/lib/apt/lists/*cuda*Packages | grep "Package:"

或查看下方列表：

Meta Package	Purpose
cuda	Installs all CUDA Toolkit and Driver packages. Handles upgrading to the next version of the cuda package when it’s released.
cuda-12-2	Installs all CUDA Toolkit and Driver packages. Remains at version 12.1 until an additional version of CUDA is installed.
cuda-toolkit-12-2	Installs all CUDA Toolkit packages required to develop CUDA applications. Does not include the driver.
cuda-toolkit-12	Installs all CUDA Toolkit packages required to develop applications. Will not upgrade beyond the 12.x series toolkits. Does not include the driver.
cuda-toolkit	Installs all CUDA Toolkit packages required to develop applications. Handles upgrading to the next 12.x version of CUDA when it’s released. Does not include the driver.
cuda-tools-12-2	Installs all CUDA command line and visual tools.
cuda-runtime-12-2	Installs all CUDA Toolkit packages required to run CUDA applications, as well as the Driver packages.
cuda-compiler-12-2	Installs all CUDA compiler packages.
cuda-libraries-12-2	Installs all runtime CUDA Library packages.
cuda-libraries-dev-12-2	Installs all development CUDA Library packages.
cuda-drivers	Installs all Driver packages. Handles upgrading to the next version of the Driver packages when they’re released.

选择你需要的包进行安装，这里选择 cuda-11.8

sudo apt-get install cuda-11-8

此安装包中包含显卡驱动，安装过程中，会让你输入密码，请记住该密码，后面重启电脑进入 Perform MOK managment 会使用到。

安装完成后，重新启动系统：

sudo reboot

配置 Perform MOK managment
MOK management
选择 Enroll MOK （注册）-> 选择 Continue -> 选择 Enroll the key -> 选择 Yes -> 键入步骤3中输入的密码->选择 Reboot 重启电脑，完成英伟达显卡驱动安装。

配置环境变量

使用 vim 编辑 ~/.bashrc 文件。

sudo vim ~/.bashrc

在文件结尾添加以下内容：

export PATH=/usr/local/cuda-11.8/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-11.8/lib64\${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

${PATH:+:${PATH}} 是一个用于设置环境变量的 Bash Shell 中的特殊语法。它的作用是在添加新路径到环境变量时，确保如果原始变量（在这种情况下是 $PATH）已经包含一些路径，那么新路径会添加在原有路径的末尾，而且它们之间会用冒号 : 分隔。
具体来说，${PATH:+:${PATH}} 的含义是：
如果 $PATH 已经定义（非空），那么它会在新路径之前加上一个冒号 :，然后再添加新路径。
如果 $PATH 未定义或为空，那么它只会添加新路径，不会加冒号。
这个语法的目的是确保在向 $PATH 添加新路径时，保持路径之间用冒号分隔，以确保环境变量的正确格式。这在很多环境变量的设置中都很有用，因为它避免了路径之间缺少分隔符而导致的错误。

LD_LIBRARY_PATH 是一个环境变量，用于指定动态链接器（dynamic linker）在运行可执行文件时搜索共享库文件（动态链接库或共享对象文件）的路径。在 Linux 和类Unix系统中，共享库文件包含在各种程序中，允许多个程序共享相同的库，从而减少内存占用并提高系统的效率。

刷新配置
在终端中运行以下命令，以使新的环境变量设置生效：

source ~/.bashrc

验证安装

首先，我们需要安装一些CUDA示例所需的第三方库。这些示例通常会在构建过程中检测所需的库，但如果未检测到，您需要手动安装它们。打开终端并执行以下命令：

sudo apt-get install g++ freeglut3-dev build-essential libx11-dev \libxmu-dev libxi-dev libglu1-mesa libglu1-mesa-dev libfreeimage-dev

完成第三方库依赖安装后，从 github 下载 https://github.com/nvidia/cuda-samples 源代码。

下载完成后，可以使用以下命令编译：

cd cuda-sample
sudo make

注意切换到你安装 cuda 版本的分支，这里是 v11.8。

可以完成整个编译，那么说明安装过程没有问题了。

在源代码目录执行 ./bin/x86_64/linux/release/deviceQuery 命令,结果如下所示：

安装 cuDNN

安装 cuDNN库和 cuDNN 示例

sudo apt-get install libcudnn8=${cudnn_version}-1+${cuda_version}
sudo apt-get install libcudnn8-dev=${cudnn_version}-1+${cuda_version}
sudo apt-get install libcudnn8-samples=${cudnn_version}-1+${cuda_version}

根据以下内容进行替换:
${cudnn_version} is 8.9.4.*
${cuda_version} is cuda12.2 or cuda11.8

使用以下命令查找与 cuDNN 版本 “libcudnn8” 相关的软件包信息

cat /var/lib/apt/lists/*cuda*Packages | grep "./libcudnn8"

输出结果如下所示：

sudo apt-get install libcudnn8-dev=8.9.4.25-1+cuda11.8
sudo apt-get install libcudnn8-samples=8.9.4.25-1+cuda11.8

验证 cuDNN

要验证 cuDNN 是否已安装并正常运行，请编译 `/usr/src/cudnn_samples_v8`` 目录中的 mnistCUDNN 示例。

cp -r /usr/src/cudnn_samples_v8/ $HOME

cd  $HOME/cudnn_samples_v8/mnistCUDNN

编译 cuDNN mnisiCUDNN 示例

$make clean && make

如报错没有找到 FreeImage.h 文件，请执行 `sudo apt-get install libfreeimage-dev`` 指令安装该依赖。

运行 mnistCUDNN 示例

 ./mnistCUDNN

如果 cuDNN 在您的 Linux 系统上正确安装并编译&运行，您将看到类似以下内容的消息：
