How to open .nsys-rep file?

Nsight Systems can only import qdstrm file, and command:

nsys profile --trace=cuda,cudnn --output=model_gn.nvvp --duration 65  ./test

dose not generate qdstrm file

My operation system and architecture is:
Ubuntu 20.04
Linux drl-dz000894 5.15.0-76-generic #83~20.04.1-Ubuntu SMP Wed Jun 21 20:23:31 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

The --output=model_gn.nvvp part of your command line forces the name of the output file, obscuring the fact that the output file is a nsys-rep file. If you remove it, or replace it with --output=model_gn then nsys will generate a file with .nsys-rep suffix.

Thanks, now I got .nsys-rep file, but how to open .nsys-req file in nsight-systems?

run nsys-ui and use the File->Open menu command.
