installation of toolkit on centos7

Dear all,

I am trying to re-install cuda toolkit 8.0 after removing the package; when I try “sudo rpm -i cuda-repo-rhel7-8.0.44-1.x86_64.rpm” the system tells that the package is already installed (even though I cannot find it in any location onthe system); then I try to go on installing cuda and the output is that the package cuda-8.0.44-1.x86_64 is already installed and updated to the last version, but I don’t see any cuda-8.0 directory, I only see a “cuda” symlink pointing to a non existing cuda-8.0. I also tried installation from runfile but it stops complaining that there is an uncomplete installation of libglvnd, even thogh during the installation of cuda drivers I chose to reinstall the library.
The output of the command nvidia-smi seems ok.
Does anyone have any suggestions?
Thanks in advance

follow the instructions in the getting started guide.

remove your broken install and re-install. You can use either the runfile installer method or the package manager method, but be sure to clean your system properly before switching from one method to the other.
