更新软件列表和必要的依赖项

sudo apt-get update# 更新软件列表

sudo apt-get install g++# 下载g++编译器

sudo apt-get install gcc# 下载gcc编译器

sudo apt-get install make# 下载GNU Make编译器

sudo apt-get install initramfs-tools # 下载安装initramfs-tools

2. 安装CUDA

步骤一: 下载CUDA安装包

进行CUDA和cuDNN的选择,也可以直接根据官方推荐进行下载安装。从Nvidia官网下载CUDA https://developer.nvidia.com/cuda-downloads

下方链接,选择更多版本 https://developer.nvidia.com/cuda-toolkit-archive

在这里插入图片描述

接下来根据提示进行下载、安装

<code>wget https://developer.download.nvidia.com/compute/cuda/11.8.0/local_installers/cuda_11.8.0_520.61.05_linux.run

sudo sh cuda_11.8.0_520.61.05_linux.run

步骤二: 安装CUDA安装包过程中的选择

Do you accept the above EULA? (accept / decline / quit):

是否接受最终用户许可协议,输入accept

在这里插入图片描述

回车键进行勾选,X就是选中,没有X就是没有选中,把安装驱动进行取消。之后向下键,回车确认

在这里插入图片描述

最后点击 install

出现了警告信息,对安装无影响

在这里插入图片描述

截图日志:

<code>wit622@622:~/cuda$ sudo sh cuda_11.8.0_520.61.05_linux.run

[sudo] wit622 的密码:

===========

= Summary =

===========

Driver: Not Selected

Toolkit: Installed in /usr/local/cuda-11.8/

Please make sure that

- PATH includes /usr/local/cuda-11.8/bin

- LD_LIBRARY_PATH includes /usr/local/cuda-11.8/lib64, or, add /usr/local/cuda-11.8/lib64 to /etc/ld.so.conf and run ldconfig as root

To uninstall the CUDA Toolkit, run cuda-uninstaller in /usr/local/cuda-11.8/bin

***WARNING: Incomplete installation! This installation did not install the CUDA Driver. A driver of version at least 520.00 is required for CUDA 11.8 functionality to work.

To install the driver using this installer, run the following command, replacing <CudaInstaller> with the name of this run file:

sudo <CudaInstaller>.run --silent --driver

Logfile is /var/log/cuda-installer.log

也可以进入日志进行查看(位置如下):

/var/log/cuda-installer.log

步骤三: 配置CUDA环境

sudo vim ~/.bashrc

在bashrc文件最下方,添加下入代码(ps:这边需要注意cuda的版本,版本不同,路径的命名需修改)

export PATH=$PATH:/usr/local/cuda-11.8/bin

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-11.8/lib64

更新环境

source ~/.bashrc

测试CUDA是否安装成功

nvcc -V

输出下述结果,表示安装成功:

wit622@622:~/cuda$ nvcc -V

nvcc: NVIDIA (R) Cuda compiler driver

Copyright (c) 2005-2022 NVIDIA Corporation

Built on Wed_Sep_21_10:33:58_PDT_2022

Cuda compilation tools, release 11.8, V11.8.89

Build cuda_11.8.r11.8/compiler.31833905_0

3. 安装cuDNN

步骤一:下载cuDNN包

https://developer.nvidia.com/rdp/cudnn-archive

例如这边选择了Download cuDNN v8.8.1 (March 8th, 2023), for CUDA 11.x点击Local Installer for Linux x86_64 (Tar)即可下载压缩包

在这里插入图片描述

将压缩包,放入自定义路径后,输入命令进行解压

<code>tar -xvf cudnn-linux-x86_64-8.8.1.3_cuda11-archive.tar.xz

解压后,输入命令,讲cuDNN对应文件拷贝至CUDA指定路径。

wit622@622:~/下载$ cd cudnn-linux-x86_64-8.8.1.3_cuda11-archive/

wit622@622:~/下载/cudnn-linux-x86_64-8.8.1.3_cuda11-archive$ ls

include lib LICENSE

sudo cp include/cudnn*.h /usr/local/cuda-11.8/include

sudo cp lib/libcudnn* /usr/local/cuda-11.8/lib64

sudo chmod a+r /usr/local/cuda-11.8/include/cudnn*.h /usr/local/cuda-11.8/lib64/libcudnn*

4. CUDA版本切换

因为后续部分项目,用的库对应的CUDA不同,无需进行修改,修改环境CUDA路径即可。例如需要11.1的CUDA,可通过修改bashrc进行修改

sudo vim ~/.bashrc

将原先的cuda-11.8注释掉,添加cuda-11.1新的环境设置,即可

# cuda-11.8

# export PATH=$PATH:/usr/local/cuda-11.8/bin

# export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-11.8/lib64

# cuda-11.1

export PATH=$PATH:/usr/local/cuda-11.1/bin

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-11.1/lib64
