Chapter 8 Deep Dream issue

[moghalis]

I am trying to run the code for the deep dream and I disable the eager execution to user the gradients. However I got this error: TypeError Traceback (most recent call last) in <cell line: 8>() 6 7 # Compute the gradients of the dream with regard to the loss. ----> 8 grads = K.gradients(loss, dream)[0] 9 #grads = K.gradients(loss, model.input)[0] 10

TypeError: You are passing KerasTensor(type_spec=TensorSpec(shape=(), dtype=tf.float32, name=None), name='tf.operators.add_3/AddV2:0', description="created by layer 'tf.operators.add_3'"), an intermediate Keras symbolic input/output, to a TF API that does not allow registering custom dispatchers, such as tf.cond, tf.function, gradient tapes, or tf.map_fn. Keras Functional model construction only supports TF API calls that do support dispatching, such as tf.math.add or tf.reshape. Other APIs cannot be called directly on symbolic Kerasinputs/outputs. You can work around this limitation by putting the operation in a custom Keras layer call and calling that layer on this symbolic input/output.
