Patch applied for this version: https://github.com/riseproject-dev/python-wheels/tree/main/patches/onnxsim/0.7.3
onnxsim vendors onnx-optimizer as a git submodule, which in turn vendors onnx (MIT) as its own submodule; onnxsim links both, plus protobuf (BSD-3-Clause), statically. protobuf pulls in abseil-cpp (Apache-2.0) the same way onnx’s own standalone build does (see docs/packages/onnx.yaml). Abseil ships no NOTICE file to propagate, and onnx-optimizer is Apache-2.0, so the wheel’s own LICENSE already covers it. The Python extension is built with nanobind rather than pybind11; nanobind ships a single py3-none-any wheel with no compiled code of its own (it only emits code into the extension it builds), so it needs no riscv64-specific handling.
