Function Usage

Builds a computational graph.

Prototype

Build a computational graph.

std::unique_ptr<Graph> BuildAndReset() const

Build a computational graph based on the output tensor list.

std::unique_ptr<Graph> BuildAndReset(const std::vector<EsTensorHolder> &outputs)

Parameters

Parameter	Input/Output	Description
outputs	Input	Tensor holder vector output.

Returns

Parameter	Type	Description
-	std::unique_ptr<Graph>	Smart pointer to the built graph. If the operation fails, nullptr is returned. After the API is called, the graph builder is no longer available.

Constraints

None

Examples

Build a computational graph.

//1. Create a graph builder (EsGraphBuilder).
EsGraphBuilder builder("graph_name");
// 2. Add two input nodes.
EsTensorHolder [data0, data1] = builder.CreateInputs<2>();
// 3. Add an intermediate node. In C++, common operators such as addition, subtraction, multiplication, and division have been overloaded for direct use.
EsTensorHolder add = data0 + data1;
// 4. Set the graph output.
builder.SetOutput(add, 0);
// 5. Build a graph and obtain the built graph object. The resources in the builder are destroyed along with the destructor.
std::unique_ptr<ge::Graph> graph = builder.BuildAndReset();
