Python warning & python error with Random Forest Classification

[tangerine-maps]

Hi, I am using QGIS 3.16.14, and newly uninstalled/reinstalled the SCP plugin today. I am trying to use Random Forest Classification, with a 4-band bandset (added as single bands), 4 MC, and when the Random Forest command is run it reaches 90% and then the QGIS log says " WARNING Python error : An error has occurred while executing Python code: See message log (Python Error) for more details."

A Python warning and Python error appear: Warning: WARNING warning:C:\Users/abc/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\SemiAutomaticClassificationPlugin\core\utils.py:7280: DeprecationWarning: QgsVectorFileWriter constructor is deprecated cfg.qgisCoreSCP.QgsVectorFileWriter(shpF, 'CP1250', f, cfg.qgisCoreSCP.QgsWkbTypes.MultiPolygon , crs, 'ESRI Shapefile')

Thanks for any suggestions as to what might be going wrong here!

As additional details, I believe SNAP is correctly installed and I only used manually drawn polygons (ROIs) for the training dataset.

I'm closing this because of the new version 8 of SCP. Please reopen it if it is still relevant in the new version. Thank you!
