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.

Functions

void AccumulateGrad(const std::string &contrib_name, std::string &acc_name, int &counter, FunctionProto &func)

Accumulates contrib_name into acc_name inside func.

If acc_name is empty, assigns it to contrib_name directly. Otherwise inserts an Add node and updates acc_name to the result.

std::string NewGradName(const std::string &prefix, int &counter)

Returns a new unique intermediate name composed of prefix and counter.

Increments counter.
