NotImplementedError: Exception encountered when calling layer "image_captioning_model_14" (type ImageCaptioningModel).

Unimplemented tf.keras.Model.call(): if you intend to create a Model with the Functional API, please provide inputs and outputs arguments. Otherwise, subclass Model with an overridden call() method.

Call arguments received:
• inputs=['tf.Tensor(shape=(None, 299, 299, 3), dtype=float32)', 'tf.Tensor(shape=(), dtype=bool)', 'tf.Tensor(shape=(None, None), dtype=float32)']
• training=False
• mask=None
