Oh sorry, i just realized i read this wrong on my mobile while on vacation. The second template parameter must be RealVector as well. i.e. single labels are encoded as vectors as size 1, as for example in LinearRegression or RandomForest

@Ulfgard If I set the second template parameter RealVector, compilation errors will occur: image image image
