tf.keras.utils.Sequence() Base object for fitting to a sequence of data, such as a dataset. Every Sequence must implement the __getitem__ and the __len__ methods. If you want to modify your dataset between epochs you may implement on_epoch_end . The method __getitem__ should return a complete batch. Notes:
