Version of Awkward Array
2.8.11
Description and code to reproduce
Description:
Calling ak.to_cudf on jagged or nested arrays fails when using cudf>=24.12.00. The internal cuDF column constructors (NumericalColumn and StructColumn) have changed their signatures, leading to TypeError when awkward attempts to pass the data keyword argument.
Reproducer:
import awkward as ak
import cudf
# 1. Jagged array failure (NumericalColumn)
arr_jagged = ak.Array([[[1, 2, 3], [], [3, 4]], []])
out_jagged = ak.to_cudf(arr_jagged)
# 2. Nested record failure (StructColumn)
arr_nested = ak.Array([{"a": {"b": 1}}, {"a": {"b": 2}}])
out_nested = ak.to_cudf(arr_nested)Error Traceback:
