v4.9.3

Added

• Segment Anything
  (SA-1B) dataset.

Changed

• Hugging Face datasets accept None values for any features. TFDS has no
  tfds.features.Optional, so None values are converted to default values.
  Those default values used to be 0 and 0.0 for int and float. Now, it's
  -inf as defined by NumPy (e.g., np.iinfo(np.int32).min or
  np.finfo(np.float32).min). This avoids ambiguous values when 0 and 0.0
  exist in the values of the dataset. The roadmap is to implement
  tfds.features.Optional.

Deprecated

• Python 3.8 support. As per
  NEP 29, TFDS now
  uses Python>=3.9.
