Worked on enhancing CUDA Python tooling by addressing two key bugs across NVIDIA/cuda-python and NVIDIA/numba-cuda repositories. Restored custom pytest terminal summary functionality in cuda-python, improving test reporting and observability for developers. In numba-cuda, removed reliance on the NUMBA_CUDA_DRIVER environment variable, instead implementing a more robust CUDA driver detection mechanism based on standard system paths and NVIDIA bindings. Updated related documentation and error messages to reflect these changes, reducing configuration friction and improving reliability. Utilized Python, CUDA, and pytest throughout the process, with a focus on testing, driver management, and clear documentation to support maintainable and dependable workflows.
