ubuntu系统下安装cuda与cudnn

一、安装依赖

1.更新

sudo apt update

sudo apt upgrade -y

2.基础工具

sudo apt install -y build-essential python

二、安装CUDA

1.文件下载

网址

https://developer.nvidia.com/cuda-toolkit-archive

依次点击

(1)“CUDA Toolkit 11.6.2”
(2)“Linux”
(3)“x86_64”
(4)“Ubuntu”
(5)“20.04”
(6)“runfile(local)”

在"Installation Instructions:"下方为下载安装指令
下载指令(文件需下载到英文路径)，如：

cd /home/heqingchun/soft/nvidia

wget https://developer.download.nvidia.com/compute/cuda/11.6.2/local_installers/cuda_11.6.2_510.47.03_linux.run

在“/home/heqingchun/soft/nvidia”路径中下载得到“cuda_11.6.2_510.47.03_linux.run”文件
以下是安装时使用的指令

sudo sh cuda_11.6.2_510.47.03_linux.run

2.cuda安装

(1)赋予可执行权限
chmod 755 cuda_11.6.2_510.47.03_linux.run
(2)运行安装
sudo sh cuda_11.6.2_510.47.03_linux.run

期间会弹出对话框，需手动输入"accept"回车，在之后再弹出对话框中取消勾选“Driver”

CUDA安装完毕

三、安装cuDNN

1.文件下载

网址

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

依次点击

(2)“Local Installer for Linux x86_64 (Tar)”

注:需要登陆，登陆成功后即可下载
下载得到“cudnn-linux-x86_64-8.4.0.27_cuda11.6-archive.tar.xz”文件放入“/home/heqingchun/soft/nvidia”目录

2.cuDNN安装

进入文件所在目录、解压文件、解压后进入文件夹、拷贝文件

cd /home/heqingchun/soft/nvidia

tar -xvf cudnn-linux-x86_64-8.4.0.27_cuda11.6-archive.tar.xz && \
cd cudnn-linux-x86_64-8.4.0.27_cuda11.6-archive && \
sudo cp include/* /usr/local/cuda-11.6/include && \
sudo cp -P lib/* /usr/local/cuda-11.6/lib64 && \
sudo chmod a+r /usr/local/cuda-11.6/include/cudnn*.h /usr/local/cuda-11.6/lib64/libcudnn*

重启电脑

3.验证安装

cat /usr/local/cuda/include/cudnn_version.h

显示如下:

/*** \file: The master cuDNN version file.*/#ifndef CUDNN_VERSION_H_
#define CUDNN_VERSION_H_#define CUDNN_MAJOR 8
#define CUDNN_MINOR 4
#define CUDNN_PATCHLEVEL 0#define CUDNN_VERSION (CUDNN_MAJOR * 1000 + CUDNN_MINOR * 100 + CUDNN_PATCHLEVEL)#endif /* CUDNN_VERSION_H */

cuDNN安装完毕
