Description

Contributes to rapidsai/build-planning#205

This PR adds support for Python 3.14.

Notes for Reviewers

This is part of ongoing work to add Python 3.14 support across RAPIDS.
It temporarily introduces a build/test matrix including Python 3.14, from rapidsai/shared-workflows#508.

A follow-up PR will revert back to pointing at the main branch of shared-workflows once all
RAPIDS repos have added Python 3.14 support.

This will fail until all dependencies have been updated to Python 3.14

CI here is expected to fail until all of this project's upstream dependencies support Python 3.14.

This can be merged whenever all CI jobs are passing.

There are segfaults across all of the Python 3.14 test jobs in pylibwholegraph.

We can't install Python 3.14 alongside CUDA 12 for cugraph-pyg due to a long-train dependency issue involving torch -> numpy -> numba (those issues might get resolved by @jameslamb work on the torch dependencies).

Given that these packages are not part of the rapids conda metapackage, and that we don't have the resources (I think) to fix up all of these issues before release, recommend letting Python 3.14 support slip to 26.06 for cugraph-pyg and pylibwholegraph.

rapids-bot bot pushed a commit that referenced this pull request Mar 17, 2026
Python 3.14 support is blocked by several segfaulting tests (#414)

Write-up and suggested path forward documented in rapidsai/build-infra#348

To avoid blocking Python 3.14 support for the rest of the release (for rapidsai/build-planning#205), adding skips to the build and test jobs here so we don't test on Python 3.14.
