Worked on the OpenSPG/KAG repository to address cross-platform compatibility issues in Python module imports, focusing on resolving a Windows-specific ModuleNotFoundError. The solution involved implementing OS-aware path parsing, ensuring that module paths were correctly interpreted using the appropriate path separators for both Windows and POSIX systems. This approach improved the reliability of Python imports across different environments, particularly benefiting development and CI pipelines. By enhancing the handling of import paths, the work reduced Windows-related errors and streamlined onboarding for contributors using various operating systems. The project demonstrated skills in Python, bug fixing, and cross-platform development within a collaborative codebase.
