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?
Contributor guide
First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
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.
