Can a frozen model be changed?

I understand that we can not re-train the weights from a Frozen Model, but is there any way to load it, and add a layer and train the extra layers at least ?

Hi @Mah_Neh, you can able to add the layers to the base model and train the model. For example

#instantiate a base model with pre-trained weights.
base_model = tf.keras.applications.Xception(
    # image shape = 128x128x3
    input_shape=(128, 128, 3),

# freeze layers
base_model.trainable = False

#create a new model on top.
inputs = tf.keras.Input(shape=(150, 150, 3))
x = base_model(inputs, training=False)
x =tf. keras.layers.GlobalAveragePooling2D()(x)
outputs = tf.keras.layers.Dense(1)(x)

model = tf.keras.Model(inputs, outputs)

Then you can compile and train your model. Thank You.
