Worked on the keras-team/keras repository to streamline backend integration by removing an obsolete NumPy compatibility patch from the tf2onnx pathway. Focused on backend development using Python, Keras, and NumPy, the work targeted legacy code that was no longer necessary after updates in NumPy 2. By eliminating the np.object workaround, initialization became more reliable and spurious warnings were reduced, resulting in a cleaner startup process for environments with newer NumPy versions. This change simplified the codebase, lowered the risk of version-related regressions, and improved error messaging, making ongoing maintenance and future updates more straightforward for the development team.
