Multi-input Keras Model with Deep Stack

[Aaryan-Nakhat]

How do I implement a weighted average ensemble using models that takes 2 inputs. I pass these 2 inputs as a list to the train_batches and val_batches parameter of the KerasMember Module and I get an error which says: AttributeError: 'list' object has no attribute 'shape'. Help will be much appreciated. Thanks in advance.
