ConvertLike¶

Versioned name : ConvertLike-1

Category : Type conversion

Short description : ConvertLike operation performs element-wise conversion on a given input tensor data to the element type of an additional input tensor like.

Detailed description

Conversion from one supported type to another supported type is always allowed. User must be aware of precision loss and value change caused by range difference between two types. For example, a 32-bit float 3.141592 may be round to a 32-bit int 3. The result of unsupported conversions is undefined, e.g. conversion of negative signed integer value to any unsigned integer type.

Output elements are represented as follows:

o[i] = Convert[destination_type=type(b)](a[i])

where a and b correspond to data and like input tensors, respectively.

Attributes : ConvertLike operation has no attributes.

Inputs

1 : data - A tensor of type T1 and arbitrary shape. Required.
2 : like - A tensor of type T2 and arbitrary shape. Required.

Outputs

1 : The result of element-wise ConvertLike operation applied to input tensor data. A tensor of type T2 and the same shape as data input tensor.

Types

T1 : any supported type
T2 : any supported type

Example

<layer ... type="ConvertLike">
    <input>
        <port id="0">        <!-- type: int32 -->
            <dim>256</dim>
            <dim>56</dim>
        </port>
        <port id="1">        <!-- type: float32 -->
            <dim>3</dim>     <!-- any data -->
        </port>
    </input>
    <output>
        <port id="2">        <!-- result type: float32 -->
            <dim>256</dim>
            <dim>56</dim>
        </port>
    </output>
</layer>
