ak.from_cudf#

Defined in awkward.operations.ak_from_cudf on line 12.

ak.from_cudf(obj, *, highlevel=True, behavior=None, attrs=None)#
Parameters:

  • obj (cudf.Series or cudf.DataFrame) – The cuDF object to convert into an Awkward Array.

  • highlevel (bool) – If True, return an ak.Array; otherwise, return a low-level ak.contents.Content subclass.

  • behavior (None or dict) – Custom ak.behavior for the output array, if high-level.

  • attrs (None or dict) – Custom attributes for the output array, if high-level.

Converts a cuDF Series or DataFrame into an Awkward Array by recursively traversing pylibcudf columns and wrapping GPU buffers with CuPy.

Note: DataFrame column names and order are preserved. Arrow/cuDF column metadata beyond field names (e.g. time-zone annotations, extension-type metadata) is not yet propagated and will be addressed in a follow-up.
