Jetson xavier failed to profile GPU data

Here, I used Nsight systems to profile GPU performance data.
Nsight systems Version: 2019.4.1.10-a76094a Linux
My target device is AGX jetson xavier
When I finished remote connection, choose CUDA trace and GPU context switch trace
Then I profiled remote target process by attaching process pid
However, for timeline view, I didn’t see viewer for GPU
I tried reboot target and restart Nsight Systems, but the problem unresolved, please tell me why
how to resolve the problem
