To Reproduce

3. error log :

one soluce i've found is to install after PYTHON official universal 3.11, Miniforge 3 and follow instructions here :

https://betterprogramming.pub/how-to-install-pytorch-on-apple-m1-series-512b3ad9bc6

and after : pip install -U demucs

I think I'm going to make diffq an optional dependency. Requiring compilation is a bit of a burden for newer Macs and the new models are not longer quantized. Adding that to my todo.

Same issue on Windows :

building 'diffq.bitpack' extension error: Microsoft Visual C++ 14.0 or greater is required. ERROR: Failed building wheel for diffq

VC 14 is installed, I've reinstalled it just in case and it still shows the error. This really makes me scratch my head.
