Worked on the PaddlePaddle/PaddleX repository to address a stability issue affecting XPU hardware. Focused on device management and bug fixing, the developer implemented a targeted solution by blacklisting the pad3d operation specifically for XPU devices, thereby preventing instability and incorrect behavior during runtime. This Python-based change was carefully scoped to minimize impact on other hardware paths, ensuring continued reliability for users deploying PaddleX on XPU. The approach demonstrated disciplined debugging and a clear understanding of hardware-specific challenges, resulting in improved production stability with minimal disruption to continuous integration processes and overall codebase maintenance during the development period.
