/**
|
* Computes the 2D average pooling of an image.
|
*
|
* @param x The input tensor, of rank 4 or rank 3 of shape
|
* `[batch, height, width, inChannels]`. If rank 3, batch of 1 is assumed.
|
* @param filterSize The filter size: `[filterHeight, filterWidth]`. If
|
* `filterSize` is a single number, then `filterHeight == filterWidth`.
|
* @param strides The strides of the pooling: `[strideHeight, strideWidth]`. If
|
* `strides` is a single number, then `strideHeight == strideWidth`.
|
* @param pad The type of padding algorithm:
|
* - `same` and stride 1: output will be of same size as input,
|
* regardless of filter size.
|
* - `valid`: output will be smaller than input if filter is larger
|
* than 1x1.
|
* - For more info, see this guide:
|
* [https://www.tensorflow.org/api_docs/python/tf/nn/convolution](
|
* https://www.tensorflow.org/api_docs/python/tf/nn/convolution)
|
* @param dimRoundingMode A string from: 'ceil', 'round', 'floor'. If none is
|
* provided, it will default to truncate.
