问题
I am new to Pytorch and one thing that I don't quite understand is the usage of nn.ModuleList and nn.Sequential. Can I know when I should use one over the other? Thanks.
回答1:
nn.ModuleList does not have a forward method, but nn.Sequential does have one. So you can wrap several modules in nn.Sequential and run it on the input.
nn.ModuleList is just a Python list (though it's useful since the parameters can be discovered and trained via an optimizer). While nn.Sequential is a module that sequentially runs the component on the input.
