Multiband diffusion not working.

[Drommer-Kille]

After git pull to latest versio, the multiband diffusion does not work. I lanch AudioCraft Plus, write TEST to prompt and hit generate. It takes quite some time to generate 10sec test. Then i go to settings and change decoder to multiband_diffusion and hit generate and get long list of errors that end to this line: TypeError: issubclass() arg 1 must be a class Files that give errors: \Python\Python310\lib\site-packages\omegaconf\dictconfig.py \Python\Python310\lib\site-packages\omegaconf_utils.py Python\Python310\lib\site-packages\omegaconf\base.py Python\Python310\lib\site-packages\omegaconf\dictconfig.py

Also, latest version seem quite slow. How can i de-bug that? It is using GPU as GPU goes 100% while generating. I have RTX3090 with 24gb VRAM.

Sadly I myself cannot play much with multiband as I do not owe a good enough graphics card, so my only way of testing is with the free version of google colab. Can you explain more on your issue? what duration did you try to generate? and what model? Ill try to replicate the issue

It happens even with 1sec duration and model is Large. But it seems that the problem is not in your end. I also git pulled the original repo and it gives the same error if multiband is selected. Lesson learned: Never update if it works.

Edit. Tried also with Small model and same error happens if multiband is selected. `loading MBD Traceback (most recent call last): File "C:\Users\Tester\AppData\Local\Programs\Python\Python310\lib\site-packages\omegaconf\dictconfig.py", line 303, in getattr return self._get_impl(key=key, default_value=DEFAULT_VALUE_MARKER) File "C:\Users\Tester\AppData\Local\Programs\Python\Python310\lib\site-packages\omegaconf\dictconfig.py", line 361, in _get_impl node = self._get_node(key=key) File "C:\Users\Tester\AppData\Local\Programs\Python\Python310\lib\site-packages\omegaconf\dictconfig.py", line 375, in _get_node key = self._validate_and_normalize_key(key) File "C:\Users\Tester\AppData\Local\Programs\Python\Python310\lib\site-packages\omegaconf\dictconfig.py", line 222, in _validate_and_normalize_key return self._s_validate_and_normalize_key(self._metadata.key_type, key) File "C:\Users\Tester\AppData\Local\Programs\Python\Python310\lib\site-packages\omegaconf\dictconfig.py", line 241, in _s_validate_and_normalize_key elif issubclass(key_type, Enum): TypeError: issubclass() arg 1 must be a class

Did it work for you on previous version? like v2.0.0?

[Drommer-Kille]

Not sure what version, the version from say 6 weeks ago. I generated a lot with multiband, also with original repo as it generated both versions (=great for creating true stereo files).
