Opening the plugin fails with error

[constantinpape]

Trying to open any of the plugins distributed via empanada-napari, e.g. 2D Inference fails with an error for me (extremely long traceback, so at the end of the issue). I have installed the plugin in a clean conda environment with the latest napari, here's the full napari info

Hi Constantin,

I reproduced the error by creating the environment with Python 3.10; everything works fine with 3.9 though. There's a note in the installation docs that says 3.10 isn't supported. Originally, I put it there because PyTorch wouldn't install with 3.10. That appears to be fixed with the newest version, but now you've discovered another reason not to use 3.10!

This appears to be a magicgui issue (I'll reach out to them to get it fixed). Apparently, there's some change in Python 3.10 that affects how floats and ints are handled.

Hi Ryan, thanks for the quick response, it works with 3.9 now!
