try this pipx runpip urh install numpy==1.26.4 pipx runpip urh install setuptools

[andrew-stclair]

That worked for me, though setuptools was already installed.

TL;DR just needed to install numpy==1.26.4 instead of numpy==2.0.0

Without setuptools, on recent versions of Python, you get

ModuleNotFoundError: No module named 'distutils'

I believe the numpy dependency could be specified in requirements.txt perhaps.

Thanks for reporting. Fixed with v2.9.8, now a regular pipx install urh works.
