ray.data.Dataset.to_modin#
- Dataset.to_modin() modin.pandas.dataframe.DataFrame [source]#
Convert this
Dataset
into a Modin DataFrame.This works by first converting this dataset into a distributed set of Pandas DataFrames (using
Dataset.to_pandas_refs()
). See caveats there. Then the individual DataFrames are used to create the Modin DataFrame usingmodin.distributed.dataframe.pandas.partitions.from_partitions()
.This is only supported for datasets convertible to Arrow records. This function induces a copy of the data. For zero-copy access to the underlying data, consider using
to_arrow_refs()
oriter_internal_ref_bundles()
.Note
This operation will trigger execution of the lazy transformations performed on this dataset.
Time complexity: O(dataset size / parallelism)
- Returns:
A Modin DataFrame created from this dataset.
