NVTX doesn't appear in timeline

Hi, I’m trying to profile PyTorch code with NSIGHT SYSTEM and NSIGHT COMPUTE.
I use the video in the link below for reference.
https://developer.nvidia.com/nsight-systems

I use command line interface when profiling, and use GUI to view the result. The command I used is

sudo /path/to/nsys profile --trace=cudnn,cuda,cublas,osrt,nvtx -o /path/to/output/file /path/to/python /path/to/train.py

And I successfully got timeline data. But, referring to the video I mentioned above, I found out that there is no nvtx event in my data. I don’t know why. I think this tag is necessary to dive deep into my analysis. Is there anyone who can give me an advice?

Sorry for the delay in getting back to you.

I’m assuming that you have added NVTX tags to your code. Can you give us the qdrep file that was generated?
