My FreeCAD 1.0.2 Python (on Windows 10) console output:

>>> import numpy
>>> import scipy
>>> print(f"NumPy version: {numpy.__version__}")
NumPy version: 1.26.4
>>> print(f"SciPy version: {scipy.__version__}")
SciPy version: 1.16.0

From what I could glean from a couple of searches, looks like these two versions are mismatched, which causes the error. Hope that helps any.

@chennes is @looooo still around ?

[chennes]

As far as I know he is still checking in from time to time.

If that is the case, this is a packaging issue.

@looooo Should I raise this issue on the FreeCAD forums, then?

[looooo]

Hmm I think it would be best to check which freecad-bundles have this issue. Then see what has to be done to fix the issue.

Also I think we are still using an old mix of dependencies for the conda-based bundles. Updating all dependencies might help to prevent this error.

Cant install :(

[iFimo]

Maybe this will help. Worked for me.

I just reinstalled FreeCAD and it worked again, but that does not seem like the Best solution. It is a Solution that works but I wouldn't like to do this if I work with Freecad, it is more like an Addon manger Problem not a the Gears workbench Problem.

[luzpaz]

Can you open a ticket on the Addon Manager repo, in that case?
Are the dependencies correct in Gears WB ?

Lets not close this without ensuring that the bug gets addressed ?

New entry with a solution in the FreeCAD Forum. https://forum.freecad.org/viewtopic.php?t=99159

The has to update Python different libraries.
