[docs]class avg_pool2d(pool2d_base): r"""Applies a 2D average pooling over an input signal composed of several input planes. In the simplest case, the output value of the layer with input size :math:`(N, H, W, C)`, output :math:`(N, H_{out}, W_{out}, C)` and :attr:`kernel_size` :math:`(kH, kW)` can be precisely described as: .. math:: out(N_i, C_j, h, w) = \frac{1}{kH * kW} \sum_{m=0}^{kH-1} \sum_{n=0}^{kW-1} input(N_i, C_j, stride[0] \times h + m, stride[1] \times w + n) If :attr:`pad` is non-zero, then the input is implicitly zero-padded on both sides for :attr:`pad` number of points. * .attr.:`kernel_size`: the size of the window * .attr.:`stride`: the stride of the window * .attr.:`pad`: implicit zero padding to be added on both sides Args: input (Tensor [N, H, W, C]): the input tensor. Return: Tensor [N, H_out, W_out, C]. """ def __init__(self, kernel_size, stride, pad) -> None: super().__init__(stride, pad, kernel_size, "avg") self._attrs["op"] = "avg_pool2d"
