Bug: App freezes due to TypeError after loading model

[will2dye4]

happen

1. Launch the app.
2. Select a model (I used htdemucs).
3. Click Load.
4. All controls in the app window are disabled, and the app does not respond to drag and drop events.

I see the following in ~/.config/demucs-gui/log right after loading the model:

Traceback (most recent call last):
  File "GuiMain.py", line 170, in showParamSettingsFunc
  File "GuiMain.py", line 382, in __init__
  File "separator.py", line 75, in getAvailableDevices
TypeError: unsupported operand type(s) for /: 'str' and 'int'

What is the platform you are using?

macOS

I guess maybe this was fixed by https://github.com/CarlGao4/Demucs-Gui/commit/c24b60cda7ffc1fb5e8461f9b48b384baa819bc0 but a new release hasn't been built yet?

[CarlGao4]

You are right, but Intel Mac will not encounter any problem without the fix and I haven't built releases for Apple Silicon I'll make sure 1.0 can run

[will2dye4]

Thanks. The version of the app published for macOS x64 seems to work (so far) on Apple Silicon, except for encountering the TypeError I described above. Are you planning to release a new version including commit https://github.com/CarlGao4/Demucs-Gui/commit/c24b60cda7ffc1fb5e8461f9b48b384baa819bc0 any time soon?
