Description

Hi all!
Trying to use torch.profiler to measure acceleration in inference of my model
https://pytorch.org/tutorials/intermediate/tensorboard_profiler_tutorial.html
I am looking at the profiling results in Tensorboard and the following question arises:
Why are the step time in the overview and the step time in the trace not the same?
Is it a bug in the torch plugin for Tensorboard?

Research direction

Start with the linked TensorBoard profiler tutorial and the torch.profiler results shown in the issue. Compare how Overview and Trace calculate or present step time, then determine whether the discrepancy is expected or indicates a plugin bug. Done means documenting the cause and identifying the affected component or a reproducible fix path.
