I think based on the src file dataset.py the compression False is not possible

        self,
        show_progress=True,
        verbose=False,
        output_url=None,

        chunk_size=None,
        max_workers=None,
        retries=3,
    ):
        # type: (bool, bool, Optional[str], Optional[str], int, Optional[int], int) -> ()
        """

        :param output_url: Target storage for the compressed dataset (default: file server)

            If -1 is provided, use a single zip artifact for the entire dataset change-set (old behaviour)
        :param max_workers: Numbers of threads to be spawned when zipping and uploading the files.
            If None (default) it will be set to:

QuizzicalFlamingo74 did u find solution?)

Hi QuizzicalFlamingo74 , Try compression=False

MinuteMouse44 unfortunately no, I created my own upload method with python Django and passed the S3 directories to the clearML dataset to track of datasets.

Which is not an ideal solution but for now it's working.
