1、cudnn安装：

sudo apt-get install zlib1g

sudo dpkg -i cudnn-local-repo-${distro}-8.x.x.x_1.0-1_amd64.deb

sudo cp /var/cudnn-local-repo-*/cudnn-local-*-keyring.gpg /usr/share/keyrings/

sudo apt-get update

sudo apt-get install libcudnn8=8.x.x.x-1+cudaX.Y

sudo apt-get install libcudnn8-dev=8.x.x.x-1+cudaX.Y

sudo apt-get install libcudnn8-samples=8.x.x.x-1+cudaX.Y

2、cudnn验证：

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

 cd $HOME/cudnn_samples_v8/mnistCUDNN

make clean && make

 ./mnistCUDNN
