Worked on the HPEEzmeral/aie-tutorials repository to enhance the reliability and compatibility of Ray-based tutorials, focusing on stability for both learners and developers. Addressed a FileNotFoundError in the Ray Tune tutorial by ensuring the model storage directory is created before use, and updated the Ray VLLM tutorial to resolve issues arising from a Ray version upgrade by providing troubleshooting guidance and removing unsupported configuration fields. Improved documentation by updating the README to reflect recent dependency changes and common issues. Utilized Python, Ray Tune, and Markdown, emphasizing troubleshooting and documentation to support a smoother user experience in post-upgrade environments.
