[ 仅 API 调用方式不一致 ]torch.nn.Unfold

torch.nn.Unfold 

          torch.nn.Unfold(kernel_size, dilation=1, padding=0, stride=1)

         

paddle.compat.nn.Unfold 

          paddle.compat.nn.Unfold(kernel_size, dilation=1, padding=0, stride=1)

         

两者功能一致，但调用方式不一致，具体如下：

转写示例

          # PyTorch 写法
unfold = torch.nn.Unfold(kernel_size=(2, 2))

# Paddle 写法
unfold = paddle.compat.nn.Unfold(kernel_size=(2, 2))
