Tensor object has no attribute keras_shape

I had a similar issue when I changed my computer with a different tensorflow version.

What solved it for me was using .shape instead of ._keras_shape

Depending on the version of tensorflow/keras and/or how you import them (from keras, from tensorflow.keras or from tensorflow.python.keras) it appears that the attributes names can differ.

If you change this:

from keras.models import Model

to this:

from tensorflow.keras.models import Model

your code will be fine.

* or *

Change this:

from tensorflow.python.keras.layers import Input

to this:

from keras.layers import Input
