Worked on stabilizing and improving the QNN Execution Provider within the mozilla/onnxruntime repository, focusing on test reliability and correctness of graph input handling. Addressed flakiness in unit tests by re-enabling and updating them to match changes in the QNN SDK, ensuring continued coverage of critical execution paths. Delivered targeted bug fixes in C++ to resolve inconsistencies in graph input counts, introducing a robust mechanism for accurate input retrieval and updating tensor metadata to prevent execution mismatches. Emphasized software development best practices and thorough unit testing, resulting in enhanced stability and reduced debugging time for diverse QNN EP model configurations.
