it's finished. The default is `False` for backward compatibility. Users of
`distributed_save` are recommended to set it to `True`.
* `tf.tpu.experimental.embedding.TPUEmbeddingV2`
* Add `compute_sparse_core_stats` for sparse core users to profile the
data with this API to get the `max_ids` and `max_unique_ids`. These
numbers will be needed to configure the sparse core embedding mid level
api.
* Remove the `preprocess_features` method since that's no longer needed.
