I was trying to add trainable variables directly to ModuleList (but that didn’t work)
    self.W = Variable(w_init, requires_grad=True)
    self.mod_list = torch.nn.ModuleList([self.W])

so then I tried to add the parameters to Module list and that didn’t work either.
    self.W = torch.nn.Parameter( w_init )
    self.mod_list = torch.nn.ModuleList([self.W])

does not work (and note w_init should NOT be a Variable, seems tensors work). Not sure why it shouldn’t but the following does work:
   self.W = torch.nn.Parameter( w_init )

without adding it to the ModuleList. Why? It feels that I am missing some conceptual thing about pytorch if it doesnt work for this. Anyone can clarify to me?
