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.
