Right now the parameters() function of nn.Container returns the parameters of the container children, but not the container itself. Problem comes from this line:

In python 3 this can simply be fixed with:

yield from super(Container, self).parameters(memo)

Or in python 2 or 3:

for p in super(Container, self).parameters(memo):
    yield p
