nvidia-smi error with ubuntu 18.04:
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
When I do ubuntu-drivers devices, I get:
== /sys/devices/pci0000:00/0000:00:1c.4/0000:03:00.0 ==

It might be because of the 2 different types of GPUs that the computer might have.
Any help is appreciated!
