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.

• See the Execution Provider page for details on specific hardware libary version requirements

ONNX opset support

ONNX Runtime supports all opsets from the latest released version of the ONNX spec. All versions of ONNX Runtime support ONNX opsets from ONNX v1.2.1+ (opset version 7 and higher).

• For example: if an ONNX Runtime release implements ONNX opset 9, it can run models stamped with ONNX opset versions in the range [7-9].

• Supported Operator Data Types

  • Operators not supported in the current ONNX spec may be available as a Contrib Operator
  • How to add a custom operator/kernel

Unless otherwise noted, please use the latest released version of the tools to convert/export the ONNX model. Most tools are backwards compatible and support multiple ONNX versions. Join this with the table above to evaluate ONNX Runtime compatibility.
