onnx-data.pb.h

This header provides the compatibility Version enum expected from the protobuf-generated ONNX C++ API.

Compatibility layer for the protobuf-generated onnx-data.pb.h header from ONNX.

The reference ONNX C++ distribution generates this header from onnx-data.proto and uses it as the canonical definition point for the Version enum. Some ONNX headers vendored into onnx-light still include onnx/onnx-data.pb.h unchanged.

onnx-light does not depend on protobuf code generation, so this header provides a minimal API-compatible replacement:

• it includes onnx/common/onnx_pb.h for shared ONNX C++ symbols;

• it defines the ONNX IR Version enum expected by downstream code.

namespace ONNX_LIGHT_NAMESPACE

Enums
