AvgPoolBackward

AvgPoolBackward operation accepts diffdst tensor and srcshape tensor (optional), and calculates diffsrc tensor.

Operation Attributes

Attribute Name	Description	Value Type	Supported Values	Required or Optional
strides	Controls the strides the window is moved	s64	A s64 list containing positive values	Required
pads_begin	Controls number of zeros to be add to the front/top/left of spatial dimensions, the attribute will be ignored when auto_pad attribute is specified to same_upper, same_lower or valid	s64	A s64 list containing n on-negative values	Required
pads_end	Controls number of zeros to be add to the back/bottom/right of spatial dimensions, the attribute will be ignored when auto_pad attribute is specified to same_upper, same_lower or valid	s64	A s64 list containing n on-negative values	Required
kernel	Size of pooling window	s64	A s64 list containing positive values	Required
exclude_pad	Controls whether the padded values are counted	bool	True, False	Required
auto_pad	Controls how the paddings are calculated	string	none (default), same_upper, same_lower, valid	Optional
data_format	Controls how to interpret the shape of src and dst.	string	NCX, NXC (default)	Optional
src_shape	Denotes the shape of input of forward op	string	NCX, NXC (default)	Optional

Execution Arguments

The inputs and outputs must be provided according to the below index order when constructing an operation.

Inputs

Index	Argument Name	Required or Optional
0	diff_dst	Required

@note Either src_shape input or src_shape attribute should be provided. If both provided, src_shape input will precede over src_shape attribute.

Outputs

Index	Argument Name	Required or Optional
0	diff_src	Required
