Use of getattr in forward function

3

Hi @ptrblck, thanks for your prompt response. The truth is that I tried to make it too simple without testing it. The above indeed works, but what I truly need is something like this:

class Net(nn.Module): 
     def __init__(self, ): 
         super().__init__()
         setattr(self, 'layer', nn.ModuleDict({'a': nn.Linear(8, 16), 'b': nn.Linear(16, 4)})) 
     def forward(self, x): 
         return getattr(self, 'layer')(x)

I just tried it and indeed it raises a NotImplementedError. It seems that the use of nn.ModuleDict causes the problem, since simple nn modules work fine.

Any ideas on how to fix it? Many thanks :slight_smile:
