cuda：7.5
cudnn：cudnn-7.0-linux-x64-v4.0-prod.tgz
cudnn样例：cuDNN v4 Code Samples
1. 解压
tar -zxvf cudnn-7.0-linux-x64-v4.0-prod.tgz
2. 复制cuda/lib64和cuda/include下文件到cuda安装目录
sudo cp lib64/* /usr/local/cuda/lib64/
sudo cp include/cudnn.h /usr/local/cuda/include/
3. 更新软链接
cd /usr/local/cuda/lib64
sudo rm -rf libcudnn.so libcudnn.so.4
sudo ln -s libcudnn.so.4.0.7 libcudnn.so.4
sudo ln -s libcudnn.so.4 libcudnn.so
4. 添加环境变量
sudo gedit /etc/profile
末尾添加export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64
source /etc/profile
5. 测试
解压cudnn code样例 cuDNN v4 Code Samples
tar -zxvf cudnn-sample-v4.tgz
cd mnistCUDNN
make
./mnistCUDNN
