v4.9.7

Added

• New datasets.

Changed

• CroissantBuilder's API to generate TFDS datasets from Croissant files.

Deprecated

Removed

Fixed

• Versions for existing datasets.

Security

v4.9.6

Added

• Full support for Python 3.12.

v4.9.5

Added

• Support to download and prepare datasets using the
  Parquet data format.

  builder = tfds.builder('fashion_mnist', file_format='parquet')
  builder.download_and_prepare()
  ds = builder.as_dataset(split='train')
  print(next(iter(ds)))

• tfds.data_source
  is pickable, thus working smoothly with
  PyGrain. Learn more by following the
  tutorial.

• TFDS plays nicely with
  Croissant. Learn more by
  following the
  recipe.

v4.9.4

Added

• A new CroissantBuilder
  which initializes a DatasetBuilder based on a Croissant
  metadata file.
• New conversion options between different bounding boxes formats.
• Better support for HuggingfaceDatasetBuilder.
• A script
  to convert a dataset from one format to another.

Changed

Deprecated

• Python 3.9 support. TFDS now uses Python 3.10

Removed

Security

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.

Removed

Fixed

Security

v4.9.2

Added

• [Experimental] A list of freeform text tags can now be attached to a
  BuilderConfig. For example:

  BUILDER_CONFIGS = [
      tfds.core.BuilderConfig(name="foo", tags=["foo", "live"]),
      tfds.core.BuilderConfig(name="bar", tags=["bar", "old"]),
  ]

  The tags are recorded with the dataset metadata and can later be retrieved
  using the info object:

  builder.info.config_tags  # ["foo", "live"]

  This feature is experimental and there are no guidelines on tags format.

Deprecated

Fixed

• Fixed generated proto files (see issue 4858).

Security

v4.9.1

Added

Changed

Deprecated

Removed

Fixed

• The installation on macOS now works (see issues
  4805 and
  4852). The ArrayRecord
  dependency is lazily loaded, so the
  TensorFlow-less path is
  not possible at the moment on macOS. A fix for this will follow soon.

Security

v4.9.0

Added

• Native support for JAX and PyTorch. TensorFlow is no longer a dependency for
  reading datasets. See the
  documentation.
• Added minival split to
  LVIS dataset.
• Mixed-human and
  machine-generated
  robomimic datasets.
• WebVid dataset.
• ImagenetPI dataset.
• Wikipedia for
  20230201.

Changed

• Support for tensorflow=2.12.

Deprecated

Fixed

Security

v4.8.3

Added

Changed

Deprecated

• Python 3.7 support: this version and future version use Python 3.8.

Removed

Fixed

• Flag ignore_verifications from Hugging Face's datasets.load_dataset is
  deprecated, and used to cause errors in tfds.load(huggingface:foo).

Security

v4.8.2

Deprecated

• Python 3.7 support: this is the last version of TFDS supporting Python 3.7.
  Future versions will use Python 3.8.

Fixed

• tfds new and tfds build better support the new recommended datasets
  organization, where individual datasets have their own package under
  datasets/, builder class is called Builder and is defined within module
  ${dsname}_dataset_builder.py.
