            dl_manager (`DownloadManager`, *optional*):
                Specific `DownloadManger` to use.
            base_path (`str`, *optional*):
                Base path for relative paths that are used to download files. This can be a remote url.
                If not specified, the value of the `base_path` attribute (`self.base_path`) will be used instead.
            file_format (`str`, *optional*):
                Format of the data files in which the dataset will be written.
                Supported formats: "arrow", "parquet". Default to "arrow" format.
                If the format is "parquet", then image and audio data are embedded into the Parquet files instead of pointing to local files.
