"""Utilities to preprocess data before training.

Deprecated: `tf.keras.preprocessing` APIs do not operate on tensors and are
not recommended for new code. Prefer loading data with either
`tf.keras.utils.text_dataset_from_directory` or
`tf.keras.utils.image_dataset_from_directory`, and then transforming the output
`tf.data.Dataset` with preprocessing layers. These approaches will offer
better performance and intergration with the broader Tensorflow ecosystem. For
more information, see the tutorials for [loading text](
https://www.tensorflow.org/tutorials/load_data/text), [loading images](
https://www.tensorflow.org/tutorials/load_data/images), and [augmenting images](
https://www.tensorflow.org/tutorials/images/data_augmentation), as well as the
[preprocessing layer guide](
https://www.tensorflow.org/guide/keras/preprocessing_layers).
