Args:
            df (`pandas.DataFrame`):
                Dataframe that contains the dataset.
            features ([`Features`], *optional*):
                Dataset features.
            info (`DatasetInfo`, *optional*):

            split (`NamedSplit`, *optional*):
                Name of the dataset split.
            preserve_index (`bool`, *optional*):
                Whether to store the index as an additional column in the resulting Dataset.
                The default of `None` will store the index as a column, except for `RangeIndex` which is stored as metadata only.
                Use `preserve_index=True` to force it to be stored as a column.

        Returns:
            [`Dataset`]
