Hi Victor,
I added 'setParameterStringList' to the code and get the following error:
VectorClassifier.SetParameterStringList("feat", "area", "perimeter",
"complexity", "_mean", "_std", "pmr")
TypeError: SetParameterStringList() takes at most 4 arguments (8 given)
when removing the commas the following error appears:
'VectorClassifier.SetParameterStringList("feat", "area" "perimeter"
"complexity" "_mean" "_std" "pmr")'
ERROR: ListViewParameter(00000000010C6F80): Value a not found in the list
of choices: .
