Worked on stabilizing device initialization for the face enhancement feature in the hacksider/Deep-Live-Cam repository, focusing on improving reliability for macOS users. Addressed a persistent bug by reverting previous changes to the macOS Metal Performance Shaders (MPS) setup and introducing a match-case platform selection using Python 3.10+ structural pattern matching. This refactoring clarified the cross-platform logic in face_enhancer.py, ensuring MPS is used on macOS when available and providing a safe fallback for other platforms. Leveraged backend development, code refactoring, and Git to reduce initialization failures, resulting in a more reliable and maintainable user experience for GFPGANer.
