Initialization error on FreeCad 1.0.1 (due to networkx python module version conflict)

[davidegalli43]

Hi all,
I'm new to FreCad and I've just installed the add-on SheetMetal.
While starting it, selecting it on the ribbbon, I obtain this initialization error on SheetMetalUnfoldCmd.

Can I do something to launch it?
Thank you.

Yeah I got same error. Check in Addon Manager and Python dep. if FC detects Networkx. In my case it does not, despite it being instaled on pc for sure. There seems to be some problem with FC Addon manager.

@davidegalli43 and @Werwolf-12
Please do the following and report the result.
In the freecad python console type the following lines and let me know the result:

import networkx
print(networkx.__version__)

if you dont see the python console, enable it from the menu:
View -> panels -> Python Console

@Werwolf-12, strange. looks like a wrong networkx module. try the following:
Type in the console networkx. do not press enter. Freecad will suggest a list of name completion. See if there is anything resembling version or ver
(make sure you made an import networkx before)

[Werwolf-12]

no, there is doc; file; loader; name; package; path, but no version or ver

[davidegalli43]

Hi @shaise,
thank you for your support.
As @Werwolf-12, networkx seems not to have a version module. The ones listed are: doc,file,loader,name,package,,path,spec.

In 2 computers I did a fresh installation this weekend and I have in both the same problem.
In a third computer where I previously installed a version of FC (and now it's the same revision as the others), networkx.vesion is 3.5 and sheet metal works fine.

@davidegalli43 , please go to the following folder:

C:\Users\<user name>\AppData\Roaming\FreeCAD\AdditionalPythonPackages\py311
Do you see any folders starting with "networkx"? (should be 2 of them)

[davidegalli43]

Now it works!
In %appDAta%Roamning.... the two ketworkx folders are now accesible too. So it was a networkx sumodule installation problem.

[shaise]

it seems so. glad it works now.

[davidegalli43]

thank you @shaise for now!
Let me know if I can give some more details to halp in fixing this issue. :)

[Werwolf-12]

It worked for me as well. Thank you very much

[luzpaz]

Is this issue then resolved ?

[shaise]

@luzpaz , since it happened to 2 people, then it is still an issue with the addon manager. They had to manually delete networkx folder then reinstall sheetmetal

[davidegalli43]

Hi,
in this computer I managed to activate it just entering the two nteworkx folders granting administrative privileges.
Then sheetmetal launched correctly.
