Subtract¶

General¶

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 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¶

Subtract operation supports the following data type combinations.

Src_0 / Src_1	Dst
f32	f32
bf16	bf16
f16	f16
