Keras rename model and layers

Question

1) I try to rename a model and the layers in Keras with TF backend, since I am using multiple models in one script. Class Model seem to have the property model.name, but when changing it I get "AttributeError: can't set attribute". What is the Problem here?

2) Additionally, I am using sequential API and I want to give a name to layers, which seems to be possibile with Functional API, but I found no solution for sequential API. Does anonye know how to do it for sequential API?

UPDATE TO 2): Naming the layers works, although it seems to be not documented. Just add the argument name, e.g. model.add(Dense(...,...,name="hiddenLayer1"). Watch out, Layers with same name share weights!

Answer 1

For changing names of model.layers with tf.keras you can use the following lines:

for layer in model.layers:     layer._name = layer.name + str("_2") 

I needed this in a two-input model case and ran into the "AttributeError: can't set attribute", too. The thing is that there is an underlying hidden attribute _name, which causes the conflict.
