ShapeOf

Versioned name: ShapeOf-3

Category: Shape manipulation

Short description: ShapeOf produces 1D tensor with the input tensor shape.

Attributes:

• output_type
  • Description: the output tensor type
  • Range of values: "i64" or "i32"
  • Type: string
  • Default value: "i64"
  • Required: No

Inputs:

• 1: Arbitrary input tensor of type T. Required.

Outputs:

• 1: 1D tensor that is equal to input tensor shape of type T_IND. Number of elements is equal to input tensor rank. Can be empty 1D tensor if input tensor is a scalar, that mean 0-dimensional tensor.

Types

• T: any numeric type.
• T_IND: int64 or int32.

Example

<layer ... type="ShapeOf">
    <data output_type="i64"/>
    <input>
        <port id="0">
            <dim>2</dim>
            <dim>3</dim>
            <dim>224</dim>
            <dim>224</dim>
        </port>
    </input>
    <output>
        <port id="1">  <!-- output value is: [2,3,224,224]-->
            <dim>4</dim>
        </port>
    </output>
</layer>
