Abs#

General#

Abs operation performs element-wise the absolute value with given tensor, it applies following formula on every element of \(\src\) tensor (the variable names follow the standard Naming Conventions):

\[\begin{split}dst = \begin{cases} src & \text{if}\ src \ge 0 \\ -src & \text{if}\ src < 0 \end{cases}\end{split}\]

Operation attributes#

Abs operation does not support any attribute.

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`	Required

Outputs#

Index	Argument Name	Required or Optional
0	`dst`	Required

Supported data types#

Abs operation supports the following data type combinations.

Src	Dst
f32	f32
f16	f16
bf16	bf16

Implementation Notes#

Abs supports in-place operations, meaning that src can be used as both input and output (dst). In case of in-place operation, the original src data will be overwritten. Use in-place operations whenever possible for performance.
