There was a problem hiding this comment.
I think you want:
dd.from_map(self._get_partition, list(range(structure.npartitions)), columns=columns)
Please do not import dask_expr directly. You should import dask.dataframe as dd and use whatever is in the namespace. dask-expr was merged into dask.dataframe and will go away now with the latest release
