ClampBackward
General
ClampBackward operation computes gradient for Clamp.
Operation attributes
| Attribute Name | Description | Value Type | Supported Values | Required or Optional | 
|---|---|---|---|---|
| The lower bound of values in the output. Any value in the input that is smaller than the bound, is replaced with the min value. | f32 | Arbitrary valid f32 value | Required | |
| The upper bound of values in the output. Any value in the input that is greater than the bound, is replaced with the max value. | f32 | Arbitrary valid f32 value | Required | |
| If true, use dst of Clamp operation to calculate the gradient. Otherwise, use src . | bool | true (default), false | Optional | 
Execution arguments
The inputs and outputs must be provided according to below index order when constructing an operation.
Inputs
| Index | Argument Name | Required or Optional | 
|---|---|---|
| 0 | src / dst | Required | 
| 1 | diff_dst | Required | 
Outputs
| Index | Argument Name | Required or Optional | 
|---|---|---|
| 0 | diff_src | Required | 
Supported data types
ClampBackward operation supports the following data type combinations.
| Src / Dst | Diff_dst | Diff_src | 
|---|---|---|
| f32 | f32 | f32 | 
| f16 | f16 | f16 | 
| bf16 | bf16 | bf16 |
