Hello, I'm trying to use the plugin in QGIS and Python, but there is some installing issue

Someone had some issue like this?

In the both I get some error related to this:

Hi Cesar,

Did you have another version of QAequilibraE installed in your machine prior to the one you're reporting the bug?
This seems to be a bug related to the AequilibraE version we're using right now. 

I'll suggest you to go to the qaequilibrae plugin installation folder, remove all files except __init__.py from the packages folder and re-run the external dependencies install. The location in your machine should be a subfolder of: "C:\Users\...\AppData\Roaming\QGIS"

I think this should solve your problem. If not, let me know.

Cheers, Renata.

Hello Renata,

No, it's just this version — it's the latest one.

I've already tried this solution and lots of other things: reinstalling QGIS, removing everything with QGIS from the computer, etc. I tried on my personal and company computers, and with Python locally and on Colab. Nothing worked.

But I found one solution. I installed version 25.274.17 and voilà! It worked perfectly!

I don't know what caused the problem, but this older version worked well. In any case, thanks for the quick response!

[Renata Imai]

Hey, good to know that!

I'll check what went wrong with 25.287.11 later on. Thanks for letting me know.

Renata

Cesar, 

What have you tried In Python exactly? 

We haven't seen any issues there recently so it is a bit surprising that you are facing trouble. 

Cheers, 

Pedro

In python I just tried to run the Delaunay Lines example present in the documentation. But after I found the problem in my colab and on python locally the problem is just the Windows itself and my other python versions installed.

So, probably no worries in Python.

[Pedro Camargo]

Likely a Python installation from the Windows store?  That one does not allow for sqlite extensions, and AequilibraE depends on spatialite. 

Installations directly from Python.org or through UV are recommended. 

Colab runs usually require the re-installation of NumPy (at the very least). 

Cheers, 

Pedro
