from tensorflow import keras

# Create the base model from the pre-trained model MobileNet V2
base_model = keras.applications.InceptionV3(input_shape=IMG_SHAPE,
# We cannot use the top classification layer of the pre-trained model as it contains 1000 classes.
# It also restricts our input dimensions to that which this model is trained on (default: 299x299)
