Error on multiclass classifying dataset when compare_all_model = True

[kngo107]

Hi, I'm running a very simple classifier on a multiclass dataset and want to compare the performance of all the classifying model. But I got the error below, is muticlass not supported yet for this case?

AttributeError: 'NoneType' object has no attribute 'score'

interesting. i don't think that i've yet tried that use case. i'll add this to the backlog. hopefully i can look into it tomorrow.

i'll be honest with you, we've had very little reason to work on multiclass problems at my company, so that part of our codebase is definitely less-tested and developed than binary classification or regression tasks. but this seems relatively easy to add a test for, and fix.

thanks for the bug report!
