Hi group, does the label/target variable need to be binary or can it be categorical with many

Also, does the training set need to have equal numbers of each possible label value?

I'm finding that when I train on a binary label with many more of value b than value a I don't
get any predictions in the confusion matrix for a.  Is that a known issue?
