how to use nsight compute to get the kernel performance？

[ihaterecursion]

i use command ncu --set full -o deepgemm python tests/test_core.py
but report error:
==ERROR== ERR_NVGPUCTRPERM - The user does not have permission to access NVIDIA GPU Performance Counters on the target device 0. For instructions on enabling permissions and to get more information see https://developer.nvidia.com/ERR_NVGPUCTRPERM

DeepGEMM cannot find the version of your NVCC.
You can print os.popen(f'{path} --version').read() in code before version = match.group(1), or simply run 'nvcc --version' to debug.
