Loads the named dataset into a tf.data.Dataset.

tfds.load(
    name, split=None, data_dir=None, batch_size=None, shuffle_files=False,
    download=True, as_supervised=False, decoders=None, read_config=None,
    with_info=False, builder_kwargs=None, download_and_prepare_kwargs=None,
    as_dataset_kwargs=None, try_gcs=False
)

If split=None (the default), returns all splits for the dataset. Otherwise, returns the specified split.

load is a convenience method that fetches the tfds.core.DatasetBuilder by string name, optionally calls DatasetBuilder.download_and_prepare (if download=True), and then calls DatasetBuilder.as_dataset. This is roughly equivalent to:

builder = tfds.builder(name, data_dir=data_dir, **builder_kwargs)
if download:
  builder.download_and_prepare(**download_and_prepare_kwargs)
ds = builder.as_dataset(
    split=split, as_supervised=as_supervised, **as_dataset_kwargs)
if with_info:
  return ds, builder.info
return ds

If you'd like NumPy arrays instead of tf.data.Datasets or tf.Tensors, you can pass the return value to tfds.as_numpy.

Callers must pass arguments as keyword arguments.

Args
name	str, the registered name of the DatasetBuilder (the snake case version of the class name). This can be either "dataset_name" or "dataset_name/config_name" for datasets with BuilderConfigs. As a convenience, this string may contain comma-separated keyword arguments for the builder. For example "foo_bar/a=True,b=3" would use the FooBar dataset passing the keyword arguments a=True and b=3 (for builders with configs, it would be "foo_bar/zoo/a=True,b=3" to use the "zoo" config and pass to the builder keyword arguments a=True and b=3).
split	Which split of the data to load (e.g. 'train', 'test' ['train', 'test'], 'train[80%:]',...). See our split API guide. If None, will return all splits in a Dict[Split, tf.data.Dataset]
data_dir	str, directory to read/write data. Defaults to the value of the environment variable TFDS_DATA_DIR, if set, otherwise falls back to "~/tensorflow_datasets".
batch_size	int, if set, add a batch dimension to examples. Note that variable length features will be 0-padded. If batch_size=-1, will return the full dataset as tf.Tensors.
shuffle_files	bool, whether to shuffle the input files. Defaults to False.
download	bool (optional), whether to call tfds.core.DatasetBuilder.download_and_prepare before calling tf.DatasetBuilder.as_dataset. If False, data is expected to be in data_dir. If True and the data is already in data_dir, download_and_prepare is a no-op.
as_supervised	bool, if True, the returned tf.data.Dataset will have a 2-tuple structure (input, label) according to builder.info.supervised_keys. If False, the default, the returned tf.data.Dataset will have a dictionary with all the features.
decoders	Nested dict of Decoder objects which allow to customize the decoding. The structure should match the feature structure, but only customized feature keys need to be present. See the guide for more info.
read_config	tfds.ReadConfig, Additional options to configure the input pipeline (e.g. seed, num parallel reads,...).
with_info	bool, if True, tfds.load will return the tuple (tf.data.Dataset, tfds.core.DatasetInfo) containing the info associated with the builder.
builder_kwargs	dict (optional), keyword arguments to be passed to the tfds.core.DatasetBuilder constructor. data_dir will be passed through by default.
download_and_prepare_kwargs	dict (optional) keyword arguments passed to tfds.core.DatasetBuilder.download_and_prepare if download=True. Allow to control where to download and extract the cached data. If not set, cache_dir and manual_dir will automatically be deduced from data_dir.
as_dataset_kwargs	dict (optional), keyword arguments passed to tfds.core.DatasetBuilder.as_dataset.
try_gcs	bool, if True, tfds.load will see if the dataset exists on the public GCS bucket before building it locally.

Returns
ds	tf.data.Dataset, the dataset requested, or if split is None, a dict<key: tfds.Split, value: tfds.data.Dataset>. If batch_size=-1, these will be full datasets as tf.Tensors.
ds_info	tfds.core.DatasetInfo, if with_info is True, then tfds.load will return a tuple (ds, ds_info) containing dataset information (version, features, splits, num_examples,...). Note that the ds_info object documents the entire dataset, regardless of the split requested. Split-specific information is available in ds_info.splits.
