I know there already is a topic with tihis issue, but there the user used runfile installation.
I used cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.deb when installing, I even completely removed it from my system once to reinstall and used that file to install.
But when using nvcc --version it says 7.5
I am also getting an error in another program installation: unsupported gpu architecture ‘compute 60’
and I read that compute 60 is not compatible with cuda 7.5 but it is with 8.0 so I am guessing that the first issue is causing that
