getting none values not supported error about skflow HOT 3 CLOSED

This seems like you have trainable variables without gradients. Can you
show your variables (print tf.all_variables) and probably gradients in
optimize_loss? Also you should try updating to 0.9 - there has been a lot
of issues addressed there.
