Subtract

Subtract operation performs element-wise subtraction operation with two given tensors applying multi-directional broadcast rules.

\[\dst(\overline{x}) = \src\_0(\overline{x}) - \src\_1(\overline{x})\]

Operation Attributes

Attribute Name	Description	Value Type	Supported Values	Required or Optional
auto_broadcast	Specifies rules used for auto-broadcasting of src tensors	string	none, numpy, (default)	Optional

Execution Arguments

The inputs and outputs must be provided according to the below index order when constructing an operation.

Inputs

Index	Argument Name	Required or Optional
0	src_0	Required
1	src_1	Required

@note Both src shapes should match and no auto-broadcasting is allowed if auto_broadcast attributes is none. src_0 and src_1 shapes can be different and auto-broadcasting is allowed if auto_broadcast attributes is numpy. Broadcasting is performed according to auto_broadcast value.

Outputs

Index	Argument Name	Required or Optional
0	dst	Required

Supported Data Types

Substract operation supports the following data type combinations.

Src_0 / Src_1	Dst
f32	f32
bf16	bf16
f16	f16
