Header file: #include <ge/es_graph_builder.h>
Library files: libeager_style_graph_builder_base.so and libeager_style_graph_builder_base_static.a

Function Usage

Creates a Const operator of a specified type (original pointer version) using an ABI-safe API.

Prototype

template <typename T>
EsCTensorHolder *EsCreateConstV2(EsCGraphBuilder *graph, const T *value, const int64_t *dims, int64_t dim_num, ge::DataType dt, ge::Format format = FORMAT_ND)

Parameters

Parameter	Input/Output	Description
T	Input	Tensor data type.
graph	Input	Pointer to the graph builder.
value	Input	Pointer to the tensor data.
dims	Input	Pointer to the tensor dimension array.
dim_num	Input	Number of dimensions.
dt	Input	Tensor data type.
format	Input	Tensor format. The default value is FORMAT_ND.

Returns

Parameter	Type	Description
-	EsCTensorHolder *	Tensor holder operator of the created Const. If the operation fails, nullptr is returned.

Restrictions

This API uses the CompliantNodeBuilder V2 API to construct a Const node, avoiding the risk of std::string transfer across the C++ ABIs in the old IR definition structure.

To use this API, the runtime software package must support CompliantNodeBuilder V2 symbols. To be compatible with old software packages that do not contain V2 symbols, use EsCreateConst.

Example

EsCGraphBuilder *graph = EsCreateGraphBuilder("graph_name");
std::vector<int64_t> data = {1, 2, 3};
std::vector<int64_t> dims = {3};
auto const_tensor = ge::es::EsCreateConstV2<int64_t>(graph, data.data(), dims.data(), dims.size(), ge::DT_INT64);
