Function Description

Exits the current frame to its parent frame. The Exit operator works with the Enter operator to create loops in a graph. It passes the input tensor x to the parent frame to make the tensor available there. The output tensor y has the same shape and data type as the input tensor x.

Parameter Description

Parameter Name	Input/Output/Attribute	Description	Data Type	Data Format
x	Input	Input tensor, which needs to be passed to the parent frame.	float16, float32, float64, int8, int16, int32, int64, uint8, uint16, uint32, uint64, bool	ND
y	Output	Tensor that has the same shape and data type as the input tensor x.	float16, float32, float64, int8, int16, int32, int64, uint8, uint16, uint32, uint64, bool	ND

Constraint Description

• The data type and shape of the output tensor y must be consistent with those of the input tensor x.

Invocation Description

The Exit operator is a control flow operator. It usually works with the Enter operator to create loops in a graph and is not invoked separately.

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