pytorch--nn.Sequential學習

nn.Sequential
A sequential container. Modules will be added to it in the order they are passed in the constructor. Alternatively, an ordered dict of modules can also be passed in.

一個有序的容器，神經網絡模塊將按照在傳入構造器的順序依次被添加到計算圖中執行，同時以神經網絡模塊為元素的有序字典也可以作為傳入參數。

直白理解：將網絡的各個層組合到一起

# Example of using Sequential
        model = nn.Sequential(
                  nn.Conv2d(1,20,5),
                  nn.ReLU(),
                  nn.Conv2d(20,64,5),
                  nn.ReLU()
                )

        # Example of using Sequential with OrderedDict
        model = nn.Sequential(OrderedDict([
                  ('conv1', nn.Conv2d(1,20,5)),
                  ('relu1', nn.ReLU()),
                  ('conv2', nn.Conv2d(20,64,5)),
                  ('relu2', nn.ReLU())
                ]))
