Constant¶

Versioned name : Constant-1

Category : Infrastructure

Short description : Constant operation produces a tensor with content read from binary file by offset and size.

Attributes

offset
- Description : specifies position in binary file with weights where the content of the constant begins; value in bytes
- Range of values : non-negative integer value
- Type : int
- Required : yes
size
- Description : size of constant content in binary files; value in bytes
- Range of values : positive integer bigger than zero
- Type : int
- Required : yes
element_type
- Description : the type of element of output tensor
- Range of values : u1, u8, u16, u32, u64, i8, i16, i32, i64, f16, f32, boolean, bf16
- Type : string
- Required : yes
shape
- Description : the shape of the output tensor
- Range of values : list of non-negative integers, empty list is allowed, which means 0D or scalar tensor
- Type : int[]
- Required : yes

Outputs

1 : Output tensor of type T.

Types

T : any type from element type values.

Example

<layer ... type="Constant">
    <data offset="1000" size="256" element_type="f32" shape="8,8"/>
    <output>
        <port id="1">
            <dim>8</dim>
            <dim>8</dim>
        </port>
    </output>
</layer>
