My nvidia driver is
NVRM version: NVIDIA UNIX x86_64 Kernel Module 384.130 Wed Mar 21 03:37:26 PDT 2018
And my cuda version is 

 nvcc: NVIDIA (R) Cuda compiler driver 
 Copyright (c) 2005-2017 NVIDIA Corporation
 Built on Fri_Sep__1_21:08:03_CDT_2017
 Cuda compilation tools, release 9.0, V9.0.176

I'm sure i have install the nvidia-driver and cuda in the right way,and i want to install cudnn with 'libcudnn7_7.5.0.56-1+cuda9.0_amd64.deb'. I typed in 'sudo dpkg -i libcudnn7_7.5.0.56-1+cuda9.0_amd64.deb' in terminal but when i tested with cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2 ,it shows that cat: /usr/local/cuda/include/cudnn.h: No such file or directory,i think i fail to install cudnn.I try to double click the .deb file to install ,and i did choose the 'install' option,but it also shows cat: /usr/local/cuda/include/cudnn.h: No such file or directory, so I don't know what to do .I can't find cudnn.h in any cuda file. BTW I can't find the other cudnn file in .tar or .tar.gz format . thank a lot.

  • When you install Cudnn using deb file you can find out the Cudnn version using : `sudo apt search cudnn | grep installed` and not `cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2`. The later command is if you use tar file and not deb file. – Neeraj Komuravalli Oct 22 '20 at 13:46
