I'm a beginner and I'm following this guide on how to create a deep learning environment. Nvidia-smi was working when I installed nvidia drivers, but after installing Cuda (which went successfully) it stopped working properly. Output:

nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

nvidia-settings

ERROR: NVIDIA driver is not loaded


ERROR: Unable to load info from any available system

Secure boot is disabled, I have tried rebooting, and sudo prime-select nvidia

    During those installation steps, in the step for installing the CUDA itself from the .run file, did you unselect the NVIDIA driver install part? I have heard of issues when installing the driver that comes with the .run file. There is a chance that it might have removed the driver. Also, does your BIOS have Secure Boot disabled? – Terrance Mar 19 '20 at 17:51

    Unfortunately I didn't unselect, I typed yes for all the questions. Should I uninstall everything and start from scratch? And yes Secure Boot is disabled. – Luoa R Mar 19 '20 at 19:20

    Yes, that would be recommended to remove the driver and CUDA, then start it over. The good part is when you run the .run file for the installation, unselecting the NVIDIA driver allows you to use the driver that is compatible with your video card. – Terrance Mar 19 '20 at 19:34

    Thank you. Unselecting the driver install in Cuda solved the problem. – Luoa R Mar 20 '20 at 08:59
  • please explain how you did it. If possible by posting an Answer to your own question. – KansaiRobot Oct 20 '20 at 06:40
