No Empty State for TB Plugin

[Reubend]

If you load the TB plugin on a log directory that does not have any traces inside, it will display a loading spinner endlessly. I think there should be a message saying that no traces were loaded; other plugins (like the graph plugin, hparams plugin, images plugin, etc.) behave by displaying such a message.

Expected behavior:
the TB plugin should say that no traces were found
Actual behavior:
A spinner shows up but no error message ever shows

I also encountered the same problem。

I solved this problem in my environment. You can uninstall 'torch-tb-profiler' in your virtual environment(such as anaconda).

Maybe I don't understand fully, but I don't want to uninstall it. I just want it to show an empty state message when there are no traces found.

Do you want to see the results of the model in Tensorboard dashboard?
Tensorboard can work even after uninstalling 'torch-tb-profiler' in my environment.
During this process, there will be a warning in the following picture.

Choose option 'no'.
