can't import keras.layers.Merge

Question

I want to merge two LSTM models in Keras. I have seen many examples of importing Merge as:

from keras.layers import Merge

When I do this, I get

Answer 1

As of keras 2, the module keras.layers.merge doesn't have a generic public Merge-Layer. Instead you are supposed to import the subclasses like keras.layers.Add or keras.layers.Concatenate etc. directly (or their functional interfaces with the same names lowercase: keras.layers.add, keras.layers.concatenate etc.).

See what types of merging layers exist in the keras docs
