Used to distinguish builders with the same name but not coming from the same namespace, for example "squad"
            and "lhoestq/squad" repo IDs. In the latter, the builder name would be "lhoestq___squad".
        data_files (`str` or `Sequence` or `Mapping`, *optional*):
            Path(s) to source data file(s).
            For builders like "csv" or "json" that need the user to specify data files. They can be either
            local or remote files. For convenience, you can use a `DataFilesDict`.
        data_dir (`str`, *optional*):
            Path to directory containing source data file(s).
            Use only if `data_files` is not passed, in which case it is equivalent to passing
            `os.path.join(data_dir, "**")` as `data_files`.
            For builders that require manual download, it must be the path to the local directory containing the
            manually downloaded data.
        storage_options (`dict`, *optional*):
