📝 Summary

Summary by CodeRabbit

Chores
- Updated the supported Treelite version to 4.7.2 or later, while retaining compatibility with versions below 5.0.0.
- Applied the updated requirement across runtime, build, installation, and supported environment configurations.
- Refreshed the bundled Treelite source reference to align with the updated version.
- Ensured supported CUDA and CPU architectures use the same compatible Treelite version range.

Walkthrough

Changes

The PR updates Treelite requirements across CMake, project metadata, Conda recipes, and CUDA environment files. The CMake configuration uses Treelite 4.7.2 with a new pinned commit.

Treelite dependency update

Layer / File(s)	Summary
Treelite source pin `cpp/cmake/thirdparty/get_treelite.cmake`	The configured Treelite version changes to 4.7.2 with a new pinned commit. The copyright notice includes affiliates.
Project dependency constraints `dependencies.yaml`, `python/cuml/pyproject.toml`	Build and runtime requirements now require Treelite 4.7.2 or newer and retain the `<5.0.0` upper bound.
Packaging and environment constraints `conda/recipes//conda_build_config.yaml`, `conda/environments/all_cuda-`	Conda recipes and CUDA environment definitions now require Treelite 4.7.2. All constraints retain the `<5.0.0` upper bound.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: ⚪ Minimal · up to dbe2d

This updates Treelite to 4.7.2 across project and conda dependency definitions, restoring compatibility with newer scikit-learn and XGBoost integrations. The required packaging update is reported as merged, and no current merge-blocking issue remains.

I updated to latest main to start a new CI run for you, I know there have been some fixes merged in recent days.

betatim · 2026-08-31T07:21:41Z

Could you investigate the failures @chyunsu3? Apparently the conda solver can't find treelite 4.7.1? If we could get CI green we could merge this I think

specification to a version available from the configured channels, avoiding the
unsatisfiable minimum of 4.7.2 while preserving the intended upper bound.

In `@dependencies.yaml`:
- Line 354: Update the conda recipe’s treelite_version selector in
conda_build_config.yaml to require >=4.7.2 and remain <5.0.0, keeping it aligned
with the treelite dependency anchor and the host/run selectors in recipe.yaml.

Apply the same fix in `@conda/environments/all_cuda-129_arch-aarch64.yaml` at line
87: The environment requirement is already raised to 4.7.2.

Waiting on conda-forge/treelite-feedstock#99. This will now incorporate the latest fix for scikit-learn (dmlc/treelite#698).

conda-forge/treelite-feedstock#99 has been merged, so we can go ahead and merge this.

Conda is currently failing with error

conda_libmamba_solver.conda_build_exceptions.ExplainedDependencyNeedsBuildingError: Unsatisfiable dependencies for platform linux-64: {MatchSpec("python[version='>=3.12,<3.13.0a0',build=*_debug_cpython]")}
Could not solve for environment specs
The following package could not be installed
└─ python >=3.12,<3.13.0a0 *_debug_cpython does not exist (perhaps a typo or a missing channel).

The error was caused by a broken recipe for Python 3.12 in Conda-forge. See conda-forge/python-feedstock#923. A few minutes ago, the fix was just published at conda-forge/python-feedstock#921. I will re-try in a moment.
