From 9c5cd818b21aa06721d880c83c6c573642fed23f Mon Sep 17 00:00:00 2001 From: James Lamb <jlamb@nvidia.com> Date: Tue, 19 Nov 2024 11:33:50 -0600 Subject: [PATCH] fix library-loading issues in editable installs (#17338) Contributes to https://github.com/rapidsai/build-planning/issues/118 The pattern introduced in #17316 breaks editable installs in devcontainers. In that type of build, `libcudf.so` is built outside of the wheel but **not installed**, so it can't be found by `ld`. Extension modules in `cudf` and `pylibcudf` are able to find it via RPATHs instead. This proposes: * try-catching the entire library-loading attempt, to silently do nothing in cases like that * ~adding imports of the `cudf` and `pylibcudf` libraries in the `devcontainers` CI job, as a smoke test to catch issues like this in the future~ *(edit: removed those, [`devcontainer` builds run on CPU nodes](https://github.com/rapidsai/shared-workflows/blob/4e84062f333ce5649bc65029d3979569e2d0a045/.github/workflows/build-in-devcontainer.yaml#L19))* ## Notes for Reviewers ### How I tested this Tested this approach on https://github.com/rapidsai/kvikio/pull/553 # Authors: - James Lamb (https://github.com/jameslamb) - Matthew Murray (https://github.com/Matt711) Approvers: - Bradley Dice (https://github.com/bdice) - Matthew Murray (https://github.com/Matt711) URL: https://github.com/rapidsai/cudf/pull/17338 --- python/libcudf/libcudf/load.py | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) diff --git a/python/libcudf/libcudf/load.py b/python/libcudf/libcudf/load.py index a91fbb7aecf..c3ff5534e87 100644 --- a/python/libcudf/libcudf/load.py +++ b/python/libcudf/libcudf/load.py @@ -76,9 +76,15 @@ def load_library(): # Prefer the libraries bundled in this package.
