*   Add name argument to tf.string_split and tf.strings_split
    *   Minor change to SavedModels exported from Keras using
        tf.keras.experimental.export. (SignatureDef key for evaluation mode is
        now "eval" instead of "test"). This will be reverted back to "test" in
        the near future.
    *   Updates binary cross entropy logic in Keras when input is probabilities.
