Developed a sub-package installation capability for Python multi-package projects within the hawk-ai-aml/github-actions repository, focusing on enhancing CI/CD workflows. The work introduced a new input, subPackagesDirs, to the GitHub Actions workflow, allowing users to specify sub-packages for installation. Leveraging YAML for workflow configuration and Python packaging best practices, the update automated the creation of virtual environments and installation of development dependencies for each sub-package. This enabled comprehensive testing and builds across multi-package repositories, streamlining onboarding and reducing manual configuration. The solution laid the groundwork for scalable, maintainable CI processes tailored to complex Python project structures without addressing bug fixes.
