ClampBackward

ClampBackward operation computes gradient for Clamp.

Operation Attributes

Attribute Name	Description	Value Type	Supported Values	Required or Optional
min	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
max	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
use_dst	If true, use dst of Clamp operation to calculate the gradient. Otherwise, use src.	bool	true (default), false	Optional
