Linux: <class 'ImportError'>: IfcOpenShell not built for 'linux/64bit/python3.10'

Ok that one is easy. Your version of ifcopenshell is not built for the same python version of FreeCAD (3.10). I don't know where your ifcopenshell comes from (is it included in the flatpack? that would be a serious problem). The easiest way is to head here: https://blenderbim.org/docs-python/ifcopenshell-python/installation.html and download a py3.10 version. You might need to find and remove the old one though. It should just be a matter of locating the 'ifcopenshell' folder and deleting it.

Windows: class 'ImportError'>: cannot import name 'api' from 'ifcopenshell' (C:\Users%username%\AppData\Local\Programs\FreeCAD 0.21\bin\lib\site-packages\ifcopenshell_init_.py)

That one is less easy to debug because I don't have a windows install to check, but more than probably a similar reason: ifcopenshell not properly installed. Maybe try and grab a windows version from the page above (beware that your windows version uses python 3.8, not 3.10).

The Windows one was easy I replaced the mentioned directory with the downloaded from blenderbim.
On the other side. I do not know how Flatpak works and where to replace a directory.

from freecad-nativeifc.

We could do some investigating inside the BIM or NativeIFC addon and advise the user better on what to do...

You could try this to know the ifcopenshell location: Inside the FreeCAD python console, type:

import ifcopenshell
print(ifcopenshell.__file__)

But maybe you can simply drop the new ifcopenshell folder somewhere FreeCAD will find it, ex. in one of the folders shown by this:

import sys
for p in sys.path:
    print(p)

Hopefully it will override the flatpack one

from freecad-nativeifc.

This command

import ifcopenshell
print(ifcopenshell.__file__)

create this output on FreeCAD on Flatpack

I found IfcOpenShell on
~/.var/app/org.freecadweb.FreeCAD/data/FreeCAD/AdditionalPythonPackages/py310/ifcopenshell
/var/lib/flatpak/app/org.freecadweb.FreeCAD/current/active/files/lib/python3.10/site-packages/ifcopenshell

from freecad-nativeifc.

At a glance it looks like a Flatpak issue. Perhaps a glibc incompatibility? Similar to IfcOpenShell/IfcOpenShell#2706

from freecad-nativeifc.

That's way above my abilities and skills. I'm not able to follow here. If you guide me I follow. But I'm not a developer. For me it's not anymore that important because I have a working FreeCAD on Windows.

from freecad-nativeifc.

Does the flatpak version use local python libs? Could you check this @Mannshoch?

import sys
for p in sys.path:
    print(p)

It could give us a hint to where to put another version of ifcopenshell...

I'm not sure what can be done with the flatpak, @adrianinsaval might have an idea here?

Ok thanks, that's interesting...

So flatpak only considers its own subdirs, and the official system-wide python folders managed by the linux distribution. It discards the user-specific folders.

So basically the only way to supply one's own version of IfcOpenShell is to install it system-wide (basically in /usr/lib/python3.10/site-packages). That's of course annoying because it requires superuser permissions and could interfere with what the distro's package manager does (in the case some day distros start providing IfcOpenShell). And even so I'm not 100% sure it will take precedence over the flatpak-supplied version.

I'm not sure what can be done here, let's wait for Adrian to chime in

from freecad-nativeifc.

Looking at this again, a possibility would be to install ifcopenshell in /home/USERNAME/.var/app/org.freecadweb.FreeCAD/data/FreeCAD/Mod/... But I'm also looking at how to build a better system from within the BIM WB to allow users to install and update ifcopenshell.

from freecad-nativeifc.

flatpak should already include ifcopenshell, but if it's installable through pip it would make sense to put it in /home/USERNAME/.var/app/org.freecadweb.FreeCAD/data/FreeCAD/AdditionalPythonPackages/py310

How do you envision this would work?

from freecad-nativeifc.

the problem is that it's evolving very fast and would need to be updated more often by the user.

Hm ifcopenshell is indeed available via pip. It lags a few versions behind: https://pypi.org/project/ifcopenshell/ but it should not be a problem (and users can request it to be updated there). Maybe that's the best option though, since all the complications of pip are now handled by the addon manager...

How do you envision this would work?

My idea was to get the ifcopenshell version, and compare with what's available on https://blenderbim.org/docs-python/ifcopenshell-python/installation.html and download and unzip the right package. But the pip way seems a lot better
