Module: tf.compat.v2.keras.utils

Keras utilities.

Classes

class CustomObjectScope: Provides a scope that changes to _GLOBAL_CUSTOM_OBJECTS cannot escape.

class GeneratorEnqueuer: Builds a queue out of a data generator.

class HDF5Matrix: Representation of HDF5 dataset to be used instead of a Numpy array.

class OrderedEnqueuer: Builds a Enqueuer from a Sequence.

class Progbar: Displays a progress bar.

class Sequence: Base object for fitting to a sequence of data, such as a dataset.

class SequenceEnqueuer: Base class to enqueue inputs.
