Issue with Semi Automatic Classification Plugin in QGIS - Python error

[elenabalma]

Help! I'm having a problem creating ROIs for a training input in QGIS. I'm using the SCP plugin but Python crashes every time I try ti create a training area ROI by drawing a polygon. I think it's a problem with the source code of the plugin, but I'm not sure.
The error message is:
