Hi,

When I type nvidia-smi, I get following error:
‘NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.’
Kindly suggest what is wrong.
I had uninstalled and installed the new nvidia driver a month back.
I ran ‘nvidia-bug-report.sh’ and generated the report and attached with
nvidia-bug-report.log.gz (110.2 KB)

Kindly suggest, how can I fix the issue?
