Detailed Description

Contains all information needed to create an OrtValue externally.

This struct aggregates the data pointer, shape, element type, and byte size that OrtApi::CreateTensorWithDataAsOrtValue requires. No ONNX Runtime headers are needed to populate or consume this struct.

auto info = *prepare_for_onnx(tensor);
OrtValue* ort_val = nullptr;
OrtMemoryInfo* mem_info = nullptr;
ort_api->CreateCpuMemoryInfo(OrtArenaAllocator, OrtMemTypeDefault, &mem_info);
ort_api->CreateTensorWithDataAsOrtValue(
    mem_info,
    info.data,
    info.byte_size,
    info.shape.data(),
    info.shape.size(),
    static_cast<ONNXTensorElementDataType>(info.element_type),
    &ort_val);

◆ is_valid()

bool signet::forge::OnnxTensorInfo::is_valid ( ) const

inline

Check whether this info is ready to be used with OrtApi::CreateTensorWithDataAsOrtValue.

Returns: true if data is non-null, byte_size > 0, shape is non-empty, and element_type is not UNDEFINED.
