During December 2024, Wang Na focused on enhancing the stability of PaddleX by addressing a hardware-specific issue affecting XPU devices. She identified and resolved a bug in the pad3d operation by blacklisting this function for XPU, thereby preventing instability and incorrect behavior during runtime. Working within the PaddlePaddle/PaddleX repository, Wang Na applied targeted debugging and device management skills, leveraging her expertise in Python to implement a concise, traceable fix. This work improved the reliability of PaddleX deployments on XPU hardware, demonstrating careful attention to edge-case handling and a disciplined approach to minimizing risk without impacting other code paths.
