Function Description

• Operator function: writes the value tensor to the specified position of the x tensor (with the offset specified by begin). This is an in-place operation, and the output shares the same memory as the input x.

Parameter Description

Parameter Name	Input/Output/Attribute	Description	Data Type	Data Format
x	Input	Target tensor, which will be modified in place.	FLOAT16, FLOAT, DOUBLE, INT32, INT64	ND
begin	Input	Start offset of the write operation. This parameter is a 1D tensor with a maximum of two elements (row_offset, col_offset).	INT32, INT64	ND
value	Input	Tensor to be written. Its dimension must be the same as that of x.	FLOAT16, FLOAT, DOUBLE, INT32, INT64	ND
x	Output	Output result, which shares the same memory as the input x (in-place operation).	FLOAT16, FLOAT, DOUBLE, INT32, INT64	ND

Constraint Description

• The dimension of x must be <= 2
• The dimension of value must be the same as the dimension of x
• begin must be a 1D tensor with two or fewer elements
• The value shape plus the begin offset must be within the x shape
• The input x and the output x must be the same memory

Invocation Description

Invocation Method	Sample Code	Description
Graph-mode API	test_geir_slice_write	Invokes the SliceWrite operator through the operator IR API.
