    If the 'dataset_query' argument is provided, then dataset is loaded from a card

    Alternatively, dataset is loaded from a provided card based on explicitly
    given parameters.

    If both are given, then the textual recipe is loaded with the key word args overriding the textual recipe args.

    Args:
        dataset_query (str, optional):
            A string query which specifies a dataset to load from
            local catalog or name of specific recipe or benchmark in the catalog. For
            example, ``"card=cards.wnli,template=templates.classification.multi_class.relation.default"``.

            This is useful when loading very large datasets.
            Loading datasets as streams avoid loading all the data to memory, but requires the dataset's loader to support streaming.

            The split of the data to load
        use_cache (bool, optional):
            If set to True, the returned Huggingface dataset is cached on local disk such that if the same dataset is loaded again, it will be loaded from local disk, resulting in faster runs.
            If set to False (default), the returned dataset is not cached.
            Note that if caching is enabled and the dataset card definition is changed, the old version in the cache may be returned.
            Enable caching only if you are sure you are working with fixed Unitxt datasets and definitions (e.g. running using predefined datasets from the Unitxt catalog).

240
241	If the 'dataset_query' argument is provided, then dataset is loaded from a card

243
244	Alternatively, dataset is loaded from a provided card based on explicitly
245	given parameters.
246
247	If both are given, then the textual recipe is loaded with the key word args overriding the textual recipe args.
248
249	Args:

251	A string query which specifies a dataset to load from
252	local catalog or name of specific recipe or benchmark in the catalog. For
253	example, ``"card=cards.wnli,template=templates.classification.multi_class.relation.default"``.
254	streaming (bool, False):
255	When True yields the data as a stream.
256	This is useful when loading very large datasets.
257	Loading datasets as streams avoid loading all the data to memory, but requires the dataset's loader to support streaming.
258	split (str, optional):
259	The split of the data to load
260	use_cache (bool, optional):
261	If set to True, the returned Huggingface dataset is cached on local disk such that if the same dataset is loaded again, it will be loaded from local disk, resulting in faster runs.
262	If set to False (default), the returned dataset is not cached.
263	Note that if caching is enabled and the dataset card definition is changed, the old version in the cache may be returned.
264	Enable caching only if you are sure you are working with fixed Unitxt datasets and definitions (e.g. running using predefined datasets from the Unitxt catalog).
