Argument constraints will be removed from Optimizer.get_updates() in Keras 2.0.7 #2

We call Optimizer.get_updates with self.constraints as an argument from overriden Model._make_train_function(). However, in master (that will be released in 2.0.7) this argument is removed. Although there's some legacy interface adaptor it fails with:

  File "keras/keras/engine/training.py", line 1412, in fit
    self._make_train_function()
  File "rossum-multi-gpu/data_parallel_model.py", line 161, in _make_train_function
    self.constraints,
AttributeError: 'DataParallelModel' object has no attribute 'constraints'

So,how to solve this problem? (with keras 2.0.8)
