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>
