*************cuda and cudnn settings and relink**************************

%Change the directory and Extract the cudnn file

$ tar xvzf cudnn-8.0-linux-x64-v5.1.tgz
%Rename it from 'cuda' to 'cudnn'
$ mv cuda cudnn

$ sudo cp -r cudnn /usr/local

%Change the directory and delete the original linking file, that is cuda

$ cd /usr/local

$ sudo rm -r cuda

% relink
$ sudo ln -s /usr/local/cuda-8.0 /usr/local/cuda

% creat symbolic link
