ModuleNotFoundError: No module named 'reasonable.reasonable' when packaging pyreasonable

[severin-lemaignan]

Hi!
I'm back at doing some packaging for reasonable.

Running:
cargo deb -p pyreasonable, I can easily generate a .deb file that contains:

# dpkg -L pyreasonable
/usr
/usr/share
/usr/share/doc
/usr/share/doc/pyreasonable
/usr/share/doc/pyreasonable/README.md
/usr/share/doc/pyreasonable/copyright
/usr/lib
/usr/lib/libreasonable.so

However, when I try to load it in Python, I get the following error:

# python3
Python 3.12.3 (main, Jan  8 2026, 11:30:50) [GCC 13.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import reasonable
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/root/src/reasonable/reasonable/__init__.py", line 4, in <module>
    from reasonable.reasonable import PyReasoner
ModuleNotFoundError: No module named 'reasonable.reasonable'

Any idea? Is the packaging of the python bindings supported?

I think the problem is the Python bindings are not included in the deb package; you can install them off of pypi (https://pypi.org/project/reasonable/). I'll also look into how I could included them in a deb package too

thanks for the quick answer. Yes, I could of course use pip -- and actually, I packaged python3-reasonable using wheel2deb in the past, it works fine.

I might continue doing that, but since you've added support for cargo deb, it would of course be nice to also support the python bindings.
