A couple notes on backwards compatibility I ran into yesterday when upgrading auto_ml to use the latest:

Keras now throws errors when trying to use some of the metrics they've deprecated. If you run into `UnboundLocalError: local variable 'class_name' referenced before assignment`, check that all your metrics are supported.

Keras also now ignores `nb_epoch` in favor of `epochs`. I must have misread the blog post, because I thought it would support `nb_epoch` for a bit and just use that in place of `epochs`.
