Hi, i was trying to install omnizart using pipx install omnizart, but this error occoured:

Fatal error from pip prevented installation. Full pip output in file:
/home/bob/.local/pipx/logs/cmd_2023-11-12_13.12.51_pip_errors.log

pip seemed to fail to build package:
madmom<0.17.0,>=0.16.1

Some possibly relevant errors from pip install:
error: subprocess-exited-with-error
ModuleNotFoundError: No module named 'Cython'
error: metadata-generation-failed

Error installing omnizart.

I've installed cython using pipx install Cython.
Distro: Arch
Python version: 3.11.5
Cython version: 3.0.5

same issue here on manjaro (also arch)

I tried installing cython system wide with pacman -S cython. That didn't help.
