Issue with add method in tensorflow : AttributeError: module 'tensorflow.python.framework.ops' has no attribute '_TensorLike'

Question

import keras as K from keras.models import Sequential from keras.layers import Dense from tensorflow import set_random_seed  for hidden_neuron in hidden_neurons:   model = Sequential() 

model.add(Dense(hidden_neuron, input_dim=61, activation='relu'))

-> i am getting error at this line. I am not really sure what am i missing here.

Traceback (most recent call last):

Answer 1

For me, the fix was importing

from tensorflow.keras import Sequential from tensorflow.keras.layers import Conv2D, Flatten, Dense 

instead of

from keras import Sequential from keras.layers import Conv2D, Flatten, Dense 

There seems to be some weird compatibility issues between keras and tensorflow.keras

Answer 2

You can use the following import command:

from tensorflow.keras.layers import ...  

instead of the 'old' one:

from keras.layers import .... 

As described here.
