Reload mode not working with indirectly referenced modules

[JackismyShephard]

Describe the bug

This is a duplicate of #8917, which has been closed. As explained on that issue, reload mode does not actually incorporate changes from indirectly referenced modules. It was suggested to use the --watch-dirs option to include indirectly referenced modules but that option does not seem to have an effect: I tried supplying the specific subfolder where a changed backend file is located and it did not solve the problem. Regardless of whether that option is used all changed files are tracked on the terminal but no reloading of indirectly referenced files happens:

Yeah this issue is still not solved. Did you try the code snippet on the referenced pr (now closed)

[Shinyzenith]

Apologies, I didn't try the referenced pr. I just ran my app as gradio main.py and hot reloads were working fine. Did I misunderstand the issue?

[JackismyShephard]

@Shinyzenith Apologies I meant to say the referenced issue #8917. If you follow the reproduction there I think you should be able to observe what I describe.

[Shinyzenith]

Hi, I tried the minimal reproduction in #8917 .

Gradio does log Changes detected in... but the app doesn't reflect the changes live even after a reload.

Exactly, that is my point.

Reload mode is not working at all for your @mluogh or is it specifically the issue @JackismyShephard brought up about reloading external modules.

@JackismyShephard thanks for filing. I will take a look.

[mluogh]

Sorry for the lack of detail.

Same issue about external modules. Same thing where it logs "Change detected..." but doesn't change.

In my case I have a main_page gradio.app which has subpages in ui/subpage.py which reference libraries in e.g. lib/foo.py.

Changes to foo.py do not reload anything.

Python 3.10, Gradio 5.22.

Thanks
