Issues about "AdversarialOptimizerScheduled" optimizer

[duolinwang]

Thank you for your great work! I recently tried the AdversarialOptimizerScheduled optimizer for two players, however, I got this error " File "build/bdist.linux-x86_64/egg/keras_adversarial/adversarial_model.py", line 171, in _make_train_function File "build/bdist.linux-x86_64/egg/keras_adversarial/adversarial_optimizers.py", line 100, in make_train_function TypeError: unsupported operand type(s) for +: 'NoneType' and 'list' " Do you have any comments on this error? Thank you so much!
