namespace onnx_light

Alias that makes onnx-light headers compatible with code that references ONNX_LIGHT_NAMESPACE (the macro used in the standard onnx package).

Set to ONNX_LIGHT_NAMESPACE so both names resolve to the same namespace.

Symbol-visibility attribute for the public onnx-light C++ API.

Maps the upstream compatibility macro to onnx-light’s explicit proto ABI annotation. This keeps declarations from vendored ONNX headers visible when lib_onnx_proto uses hidden visibility by default.

Namespace alias so that ONNX C++ code (and consumers such as onnxruntime) that refers to the literal onnx namespace — rather than the ONNX_NAMESPACE macro — resolves to the onnx-light namespace. The standard onnx package lives in namespace onnx; onnx-light uses onnx_light (via ONNX_LIGHT_NAMESPACE), so this alias keeps onnx-light a true drop-in. It is only introduced when the onnx-light namespace differs from onnx.

class DefaultVersionConverter : public onnx_light::version_conversion::BaseVersionConverter#
#include <convert.h>

Public Functions

inline DefaultVersionConverter()#
virtual ModelProto convert_version(const ModelProto &mp_in, const OpSetID &initial_version, const OpSetID &target_version) const override#

Converts a model from one opset version to another.

Parameters:

  • mp_in – Input model.

  • initial_version – Source opset identifier.

  • target_version – Target opset identifier.

Returns:

Converted model.
