I want to do something like:
class Foo(nn.Module):
    def __init__(self, featurizer):
        self.featurizer = featurizer
   ....

… so I want to use featurizer in the forward method. But I dont want featurizer (which is derived from nn.Module) to have its parameters included in the .parameters() of a Foo object.
How to achieve this? I know I could do eg assign a list to Foo, and then add the featurizer to this list, but that seems a bit … convoluted. Wodnering if there is some simpler way?
(edit: for now, I’ve done exactly the create a list thing:
    self.featurizer_l = [featurizer]

and in forward:
    x = self.featurizer_l[0](x)
