Chapter 11 : Reusing a Keras model

Hi @ageron

I am getting an error " ValueError: The name "dense" is used 2 times in the model. All layer names should be unique." with the last line in Cell 60.

Just to rule out any errors from my side, I copied the code from the Note book from github, still receiving the same error. I even tried restarting the kernal as well as issuing a keras.backend.clear_session(). But no success.

So, I added a customized name for the time being to move forward as below:
model_B_on_A.add(keras.layers.Dense(1, name = "dense_final", activation="sigmoid"))

My environment:
tensorflow 2.0.0,
keras 2.2.4-tf
Python 3.7.6

Not sure whether I did some thing wrong to get the above error or does it need the 'name' parameter for the last layer to remove ambiguity.

Thanks
Satya
