Problem with Classify vector by ROC

[ernesto561]

Thanks for the plugin. It's an easy way to create landslide susceptibility models. However, I have had problems running the tools.

I installed it in Windows 11 Pro from the QGIS plugin repository, using QGIS 3.44.1-Solothurn. When I try to run the tool "Classify vector by ROC", using the test data, I get the following error:

Input parameters:
{ 'INPUT' : 'C:/Users/mreyes.AMBIENTE/Downloads/SZ-plugin-master/test_data/out.gpkg|layername=out', 'NUMBER' : 4, 'OUTPUT3' : 'TEMPORARY_OUTPUT', 'STRING' : 'SI', 'STRING2' : 'y' }

Traceback (most recent call last):

The above exception was the direct cause of the following exception:

It's the same error for the tool "ROC".
