Versioned name: Multiply-1

Category: Arithmetic

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

OpenVINO description: This OP is as same as OpenVINO OP


  • 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


  • 1: A tensor of type T. Required.

  • 2: A tensor of type T. Required.


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


  • 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 Multiply does the following with the input tensors a and b:

\[o_{i} = a_{i} * b_{i}\]
