# Pow¶

Versioned name: Pow-1

Category: Arithmetic

Short description: Pow performs element-wise power operation with two given tensors applying multi-directional broadcast rules.

OpenVINO description: This OP is as same as OpenVINO OP

Attributes:

• auto_broadcast

• Description: specifies rules used for auto-broadcasting of input tensors.

• Range of values:

• none - no auto-broadcasting is allowed, all input shapes should match

• numpy - numpy broadcasting rules, aligned with ONNX Broadcasting. Description is available in ONNX docs.

• Type: string

• Default value: “numpy”

• Required: no

Inputs

• 1: A tensor of type T. Required.

• 2: A tensor of type T. Required.

Outputs

• 1: The result of element-wise power operation. A tensor of type T. Required.

Types

• T: any numeric type.

Detailed description:

Before performing arithmetic operation, input tensors a and b are broadcast if their shapes are different and auto_broadcast attributes is not none. Broadcasting is performed according to auto_broadcast value.

After broadcasting Pow does the following with the input tensors a and b:

$o_{i} = {a_{i} ^ {b_{i}}}$
