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  |
