cuda、cudnn 安装

1. cuda 安装

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

选择需要的版本：https://developer.nvidia.com/cuda-12-2-0-download-archive?target_os=Linux&target_arch=x86_64&Distribution=Ubuntu&target_version=22.04&target_type=runfile_local

python 复制代码

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

2. cudnn 安装

2.1 deb方法

访问https://developer.nvidia.com/cudnn-downloads?target_os=Linux&target_arch=x86_64&Distribution=Ubuntu&target_version=22.04&target_type=deb_local

bash 复制代码

wget https://developer.download.nvidia.com/compute/cudnn/9.2.1/local_installers/cudnn-local-repo-ubuntu2204-9.2.1_1.0-1_amd64.deb
sudo dpkg -i cudnn-local-repo-ubuntu2204-9.2.1_1.0-1_amd64.deb
sudo cp /var/cudnn-local-repo-ubuntu2204-9.2.1/cudnn-*-keyring.gpg /usr/share/keyrings/
sudo apt-get update
sudo apt-get -y install cudnn

对于cuda12

bash 复制代码

sudo apt-get -y install cudnn-cuda-12

如果是cuda11

bash 复制代码

sudo apt-get -y install cudnn-cuda-11

2.2 tar方法

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

根据需求选择：

如下图所示，也可以下载deb,用deb安装

复制文件：

bash 复制代码

cd \Downloads # 更改文件夹，下载后默认地址
tar -xvf cudnn-linux-x86_64-8.9.2.26_cuda11-archive.tar.xz # 解压
sudo cp cudnn-*-archive/include/cudnn*.h /usr/local/cuda/include # 复制
sudo cp -P cudnn-*-archive/lib/libcudnn* /usr/local/cuda/lib64 
sudo chmod a+r /usr/local/cuda/include/cudnn*.h /usr/local/cuda/lib64/libcudnn*

查看cudnn版本命令：

bash 复制代码

cat /usr/include/cudnn_version.h |grep CUDNN_MAJOR -A 2
