Subtract
Subtract#
Versioned name: Subtract-1
Category: Arithmetic
Short description: Subtract performs element-wise subtraction operation with two given tensors applying multi-directional broadcast rules.
OpenVINO description: This OP is as same as OpenVINO OP
Attributes:
auto_broadcast
Description: specifies rules used for auto-broadcasting of input tensors.
Range of values:
none - no auto-broadcasting is allowed, all input shapes should match
numpy - numpy broadcasting rules, aligned with ONNX Broadcasting. Description is available in ONNX docs.
Type: string
Default value: “numpy”
Required: no
Inputs
1:
input_1
- the input Minuend tensor. Required.Type: T
2:
input_2
- the input subtrahend tensor. Required.Type: T
Outputs
1:
output
- the output tensor of element-wise subtraction operation. Required.Type: T
Types:
T: f32, f16, bf16.
Note: Inputs and outputs have the same data type denoted by T. For example, if input is f32 tensor, then all other tensors have f32 data type.
Detailed description:
Before performing arithmetic operation, input_1 and input_2 are broadcasted
if their shapes are different and auto_broadcast
attributes is
not none
. Broadcasting is performed according to auto_broadcast
value.
After broadcasting Subtract does the following with the input tensors:
