How should EncoderDecoder with mixin of Encoder and Decoder be implemented?
In the following snippet self.enc is not registered as a module.
class Encoder(nn.Module):
    def __init__(self):
        super().__init__()
        self.enc = nn.Linear(2,2)

class Decoder(nn.Module):
    def __init__(self):
        super().__init__()
        self.dec = nn.Linear(2,2)
        
class EncoderDecoder(Encoder, Decoder):
    def __init__(self):
        super(EncoderDecoder, self).__init__()
        super(Encoder, self).__init__()
        print(self.modules)

EncoderDecoder()

output:
EncoderDecoder(
  (dec): Linear(in_features=2, out_features=2, bias=True)
)
