Make target label work with multi class. #10
Description
As target_label only accept single values, making it work on multi class problems is not so simple. I have written a simple looping function to iterate over the correct target labels, but as on Flair 0.8post1, I find that predictions of the interpret_sentence class deviate from the orginal multi class model (i.e. wrong class prediction).
On personal note: I think you have done a really good job in building this solution. It has worked wonders for multi label problems already.
