I can’t really tell why this failed but in general, you shouldn’t use the .run installers. General instructions for Ubuntu: - Don’t use the .run installers, use --uninstall to uninstall them - purge anything nvidia/cuda - add the ubuntu graphics ppa [url][https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa[/url]](https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa%5B/url%5D) - install the driver from that (sudo apt install nvidia-driver-430) - download the cuda .deb - add the repo to your system (first three steps from install instructions on download page) - _don’t_ install cuda - instead, run sudo apt install cuda-toolkit-10-1 (or 9-0 if you want to install cuda 9) ---

thanks for your help i have one further question once the toolkit is installed what is the file path location of these 1. cuda toolkit (because two folders are seen cuda and cuda 9.1 or wtv version) 2. gpu deployment kit thanks! ---

The 10.1 deb e.g. installs nearly everything in /usr/local/cuda-10.1 /usr/local/cuda can then be a symbolic link to the currently used cuda if more than one cuda version is installed side-by-side. ---
