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
  • Default value: none
  • Required: yes
• size
  • Description: size of constant content in binary files; value in bytes
  • Range of values: positive integer bigger than zero
  • Type: int
  • Default value: none
  • 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
  • Default value: None
  • 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[]
  • Default value: None
  • Required: Yes

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>
