原程序如下：

import torch
    import torch.nn as nn
    
    class Net():
        def __init__(self,inc,k):
            super().__init__()
            self.net = nn.Sequential(
                nn.Conv2d(inc,inc,k,2,1)
            )
        def forward(self,x):
            return self.net(x)
    
    class UpsampleLayer(torch.nn.Module):
        def __init__(self):
            super(UpsampleLayer, self).__init__()
            self.pixelShuffle = torch.nn.PixelShuffle(2)
    
        def forward(self, x):
            return self.pixelShuffle(x)
    
    if __name__ == '__main__':
        x = torch.Tensor(1,4,100,100)
        net1 = Net(4,3)
        y = net1(x)
        up = UpsampleLayer()
        y1 = up(y)
        print(y1)

按照网上常见的说法是命名冲突问题，但是我只是一个如此简单的demo，又没有占用关键字，怎么可能是命名问题。于是在第26行把  y = net1(x) 改为  y = net1.forward(x) ，告诉这个网络用其内的什么函数，就好了。。。

又如

import torch
    import torch.nn as nn
    
    class Net():
        def __init__(self,inc,k):
            super().__init__()
            self.net = nn.Sequential(
                nn.Conv2d(inc,inc,k,2,1)
            )
        def forward(self,x):
            return self.net(x)
    
    class UpsampleLayer(torch.nn.Module):
        def __init__(self):
            super().__init__()
            self.pixelShuffle = torch.nn.PixelShuffle(2)
    
        def forward(self, x):
            return self.pixelShuffle(x)
    
    class MainNet():
        def __init__(self):
            super().__init__()
            self.net1 = Net(4, 3)
            self.up = UpsampleLayer()
        def forward(self,x):
            y = self.net1.forward(x)
            return self.up(y)
    
    if __name__ == '__main__':
        x = torch.Tensor(1,4,100,100)
        mnet = MainNet()
        print(mnet.forward(x))
