[biglimp]

You need python 3.12.

[sbene2025]

Thank you for the fast reply. But Python 3.9 is the current version embedded into QGIS-LTR after installing.

[biglimp]

Ok, I see you are using a MacOS. I am not so good at that. Look through our Discussion pages and see if you find a solution.

[sbene2025]

Yes, exactly. I've already done that. there is no error which exactly reflects the mine. First I thought it might have something to do with the version of 'numpy'. but also that didn't resolve the error.

[biglimp]

@j3r3m1 , do you have any suggestions on how to solve this error?

[Jakende]

I actually have the same issue!

[biglimp]

I see you both have numpy 1.20. That version is very old. You should update and try again. QGIS comes with 1.26 now.

[j3r3m1]

There was some issues with older version of Numpy indeed. Is the issue solved with newer versions ?
