Environment

• How do you deploy Kubeflow Pipelines (KFP)?

Local development / pre-commit hooks (Python environment)

• KFP version: N/A (pre-commit hook issue, not runtime)

• KFP SDK version: N/A (pre-commit hook issue, not SDK-specific)

Steps to reproduce

Use Python 3.12+.

Install the repository’s pre-commit hooks:

pre-commit install

Try to commit code:

git commit -m "test commit"

Observe the error:

ModuleNotFoundError: No module named 'lib2to3'

Expected result

Pre-commit hooks should run successfully regardless of Python 3.12+.
yapf formatting should complete without errors.

Suggested workaround: downgrade Python (<3.12) or migrate from yapf → ruff.
