question about Multivariate data to predict Univariate (MS)

[smailyassine-oa]

Thank you for your great work, I have a question about the data loader what should be modified to make it work for MS, because keeping everything as it is it gives predictions for all the variables not only the target variable I am interested in, thus for predictions array I get a concatenated array for all variables, so I get the following plot : what changes should I make then?
