PROFILE
Shushi Hong
Over eight months, this developer contributed to the apache/tvm repository by expanding model interoperability and operator coverage in the TVM Relax stack. They engineered translation layers for PyTorch and ONNX models, enabling seamless conversion to Relax IR and supporting advanced neural network operations such as LSTM and GRU. Their work involved Python and C++ to implement operator mappings, enhance packaging with pyproject.toml, and streamline CI/CD workflows. By improving importer consistency, adding new features like RoPE scaling and AllClassNMS, and addressing edge cases in model export, they delivered robust, production-ready solutions that reduced manual translation and improved deployment reliability.
