ONNX Runtime compatibility

Contents

Backwards compatibility

Newer versions of ONNX Runtime support all models that worked with prior versions, so updates should not break integrations.

Environment compatibility

ONNX Runtime is not explicitly tested with every variation/combination of environments and dependencies, so this list is not comprehensive. Please use this as starting reference. For specific questions or requests, please file an issue on GitHub.
