Hello all,

I wanted to use the GQF module for my master thesis. While trying to start the tutorial, I encountered the following problem on 2 different computers (Windows 10). After installing UMEP (4.0.2) for QGIS (3.34) and downloading the following packages, I prepared the data sources and clicked on "Prepare input data via data sources" and after a few seconds I got:

An error has occurred while executing Python code

So, now that I've tried it on my PC and have the same problem, I hope you guys have a solution to this issue? After pressing the button once, I can no longer use it and have to restart QGIS.

Hi,
I transferred this to the issue section as this most likely is a bug. The last known time the GQF tool was working was QGIS version 3.2. Since then, QGIS has been updated multiple times and this is probably the reason of your issue. Since we do not have any one person working with GQF within our development team, I am not sure we can help you to fix this issue in the near future.

Hey, thanks for the reply. That's pretty unfortunate for me. Does no one else have any suggestions?
