The pooling2d operation calculates the output based on

Input(X) and output(Out) are in NCHW format, where N is batch size, C is the

Parameters(ksize, strides, paddings) are two elements.

These two elements represent height and width, respectively.

The input(X) size and output(Out) size may be different.

Example:
|

Input:

X shape: $(N, C, H_{in}, W_{in})$

Output:
