Installing cuDNN

This was relatively painless.

Go to NVIDIA website, log in as a developer, download cuDNN Library v5.1 for Linux (cudnn-8.0-linux-x64-v5.1.tgz)

$ cd /usr/local/cuda
$ tar xvzf cudnn-8.0-linux-x64-v5.1.tgz
$ sudo cp -P cuda/include/cudnn.h /usr/local/cuda/include
$ sudo cp -P cuda/lib64/libcudnn* /usr/local/cuda/lib64
$ sudo chmod a+r /usr/local/cuda/include/cudnn.h /usr/local/cuda/lib64/libcudnn*
