ModuleList也是一个特殊的module,可以包含几个子module,可以像用list一样使用它,但不能直接把输入传给ModuleList。 3.1 nn.Sequential() 1. 模型的建立方式: importtorchimporttorch.nn as nnfromtorch.autogradimportVariable'''nn.Sequential'''net1=nn.Sequential() net1.add_module('conv', nn.Conv2d(3, 3...
在实现 nn.ModuleList 时，若未定义 forward() 方法，传入输入数据将引发异常。通过实现 forward() 方法，可以避免此问题。与 nn.Sequential 相比，nn.Sequential 可以直接通过 x = self.combine(x) 实现前向传播，而 nn.ModuleList 则需要遵循特定的实现方式。通过比较 nn.ModuleList 和 nn.Sequential ...
需要注意的是,如果OrderedDict里面有两个组件名字重复了,那么Sequential的建立结果很可能与我们的预期不同。若第二个conv组件改名为conv1,则在Sequential里,只会有一个卷积层,处于最开头的位置,且为nn.Conv2d(20,64,5),也即是说第三行的conv1设置对第一行的conv1设置做了一个刷新(覆盖),而不是我们所想的还会...
Sequential和torch.nn.ModuleList的区别是什么?ModuleList就是一个用来存储Module的列表!另一方面,Sequential中的各层以级联方式连接。 举例: # Using Sequential to create a small model. When `model` is run, # input will first be passed to `Conv2d(1,20,5)`. The output of ...

🐛 Describe the bug Hello. After upgrading from torch 2.3.0 to torch 2.4.0 torch.compile produces much less graph breaks without "optimized" code, it supports zip(), accessing modules of nn.Sequential and other stuff. However, it also pro...
