Function Description

Provides input data for other operators. The Data operator serves as a data input node in a graph. It directly passes the input tensor x to the output tensor y, and identifies the sequence number of the data node in the network through the index attribute.

Parameter Description

Parameter Name	Input/Output/Attribute	Description	Data Type	Data Format
x	Input	Input tensor.	TensorType::ALL()	ND
index	Attribute	Index of the input tensor. The data type is int32 or int64. Assume that a network has three data nodes: one should be set to 0, another to 1, and the third to 2.	Int, with the default value 0	-
y	Output	Tensor that has the same shape and data type as the input tensor x	TensorType::ALL()	ND

Constraint Description

None

Invocation Description

The Data operator is a basic operator of the graph engine. It is usually used as a data input node in a graph and is not invoked separately.

Invocation Method	Invocation Sample	Description
Graph-mode invocation	test_geir_data	Invokes the Data operator by building a graph through the operator IR
