[inshans216]

Hi all!

When installing the latest branch of the UMEP plugin (ver 4.4.5)into an fresh install of QGIS, this error is presented and is unable to install in QGIS version 3.40.14:

Couldn't load plugin 'UMEP-SuPy-QGIS3' due to an error when calling its classFactory() method

Thank you in advance if there is another step to installing the plugin through QGIS using the plugin manager!

Sorry for this cos are having a lag in version between SUEWS/supy and UMEP. Depending on what you want to do, you can try to install supy version 2025.11.20.rc1 using pip pip install supy==2025.11.20.rc1.

Thank you so much! That allowed supy to be installed through the GIS shell. When beginning to execute SUEWSPrepare in UMEP however, this error flashed:

For reference, here is a screenshot of the SUEWSPrepare options used:

You might have found a bug. I will convert this to an issue so that we can continue searching for errors there.
