EluBackward

General

EluBackward operation computes gradient for Elu operation.

Operation attributes

Attribute Name	Description	Value Type	Supported Values	Required or Optional
alpha	Scale for the negative factor.	f32	Arbitrary non-negative f32 value	Required
use_dst	If true, use dst of Elu 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
