It seems a really common question in Ubuntu 18.04 and recent drivers this sort of problem (mostly for notebooks with two graphic boards):
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
Could you please provide some advice on how to solve this? I’m trying to solve this for days, without success.
Things I did:
- Installation following https://gist.github.com/Mahedi-61/2a2f1579d4271717d421065168ce6a73#file-cuda_10-0_installation_on_ubuntu_18-04 steps, but for CUDA 10.2
- Disabled Secure Boot
- Updated the initrd (sudo update-initramfs -u)
