WebOct 9, 2015 · If you use the default score it works, as you can see above. So you probably need to look at your predictions and understand why they are continuous (i.e. use a classifier instead of regression). Or use a different score. As an aside, if you run the regression with only one set of (column of) y values, you still get an error.
