def compute_sizes_response(dataset: str) -> tuple[DatasetSizeResponse, float]:
    """
    Get the response of 'dataset-size' for one specific dataset on huggingface.co.

    Args:
        dataset (`str`):
            A namespace (user or an organization) and a repo name separated by a `/`.

    Raises:
        [~`libcommon.simple_cache.CachedArtifactError`]:
            If the previous step gave an error.
        [~`libcommon.exceptions.PreviousStepFormatError`]:
            If the content of the previous step has not the expected format

    Returns:
        `tuple[DatasetSizeResponse, float]`: An object with the sizes_response and the progress.
