tar -zxvf cudnn-7.0-linux-x64-v3.0-prod.tgz

sudo cp cuDNN/cuda/include/cudnn.h /usr/local/cuda/include

sudo cp cuDNN/cuda/lib64/* /usr/local/cuda/lib64/

#下面的操作在/usr/local/cuda/lib64/目录下进行

sudo rm -rf libcudnn.so libcudnn.so.7.0#删除两个符号链接；

sudo ln -s libcudnn.so.7.0.64 libcudnn.so.7.0

sudo ln -s libcudnn.so.7.0 libcudnn.so

I have copied everything (3 .so files) from
/usr/local/cuda/extras/CUPTI/lib64/
to
/usr/local/cuda/lib64/

and it works
