- class torch.nn.AvgPool3d(kernel_size, stride=None, padding=0, ceil_mode=False, count_include_pad=True, divisor_override=None)¶
Applies a 3D average pooling over an input signal composed of several input planes.
In the simplest case, the output value of the layer with input size , output and
kernel_sizecan be precisely described as:
paddingis non-zero, then the input is implicitly zero-padded on all three sides for
paddingnumber of points.
When ceil_mode=True, sliding windows are allowed to go off-bounds if they start within the left padding or the input. Sliding windows that would start in the right padded region are ignored.
stridecan either be:
int– in which case the same value is used for the depth, height and width dimension
tupleof three ints – in which case, the first int is used for the depth dimension, the second int for the height dimension and the third int for the width dimension
ceil_mode (bool) – when True, will use ceil instead of floor to compute the output shape
count_include_pad (bool) – when True, will include the zero-padding in the averaging calculation
Input: or .
Output: or , where
>>> # pool of square window of size=3, stride=2 >>> m = nn.AvgPool3d(3, stride=2) >>> # pool of non-square window >>> m = nn.AvgPool3d((3, 2, 2), stride=(2, 1, 2)) >>> input = torch.randn(20, 16, 50,44, 31) >>> output = m(input)
