ERR_NVGPUCTRPERM: Permission issue with Performance Counters

Error

ERR_NVGPUCTRPERM: Permission issue with Performance Counters

Solutions for this issue

NVIDIA has a page that addresses the issue. Unfortunately, the instructions didn't solve the problem for me. However, I found a solution from rameshgunjal in the NVIDIA forums.

Option 1: Running the program as admin

You might have noticed that sudo nv-nsight-cu results in an error. Instead, you have to provide the path: sudo /usr/local/cuda/bin/nv-nsight-cu. The same applies for other applications as well: sudo /usr/local/cuda/bin/nsight-sys.
