3. Poetry

   2 417 34,278 9.1 Python

   Python packaging and dependency management made easy

   

   Project mention: Postmortem: AI Incident Classifier Failed Due to Biased Training Data and Scikit-Learn 1.5 | dev.to | 2026-05-05

   Use dependency pinning tools like Poetry (https://github.com/python-poetry/poetry) or pip-tools (https://github.com/jazzband/pip-tools) to lock all transitive dependencies, not just top-level ones. Before upgrading any ML library, audit the release notes for breaking changes to default parameters: Scikit-Learn maintains a detailed changelog at https://scikit-learn.org/stable/whats\_new.html. For critical pipelines, add a pre-commit hook that checks for unpinned dependencies or unrecognized default parameters. We reduced our dependency-related incidents by 92% after implementing this practice.
