"""tensorflow/datasets is a library of datasets ready to use with TensorFlow.

tensorflow/datasets is a library of public datasets ready to use with
TensorFlow. Each dataset definition contains the logic necessary to download and
prepare the dataset, as well as to read it into a model using the
`tf.data.Dataset` API.

Usage outside of TensorFlow is also supported.

See the README on GitHub for further documentation.
