im on kde plasma on wayland. anything i can do? (i dont speak python)

Installing it as an Arch Linux package, did you look at it’s dependencies and make sure they’ve been installed?

It’s telling you that there are dependencies missing.

The cvtracker is part of the GStreamer package.

The pkg. librosa can be installed via Python

they are not installed per dependency and are optional …

This looks like it’s the problem:

Gdk-Message: 00:51:52.570: Unable to load left_side from the cursor theme

If you’re using a custom cursor theme, you might want to try switching back to the default breeze cursor.

Yes, but only required (or hard) dependencies. The warnings that you were seeing were informational warnings, telling you that some functionality that you might want will not be available without certain optional (or soft) dependencies installed (in this case, object tracking and beat detection). The lack of those soft dependencies would not keep the application from opening or otherwise running.

In this case, the relevant error messages were the ones telling you that you had a problem in your cursor theme (LEFT_SIDE appears to be missing or corrupt).
