Unfortunately, though my code can run successfully for nvvp, my server always crashes after running the code. I have to restart my server times by times. And some functions of nvvp can’t support my server, whose compute capability is bigger than 7.2. Thus, i want to use nsight system as a substitute. For nsight systems, it shows that “found no nvidia driver”. However, the same code can run successfully for pycharm and windows’ cmd.  I have been confused for a long time.
