SCP : name 'RandomForestClassifier' is not defined

Using RF for classification, the above issue occurred while following the tutorial, and the software used was QGIS 3.44 and SCP 8.5

Hello @gaiyf ,
the issue means that the plugin dependencies were not installed.
I suggest to install QGIS 4 and follow this guide https://semiautomaticclassificationmanual.readthedocs.io/en/latest/installation.html
