WebAug 24, 2024 · You shouldn't inherit from torch.nn.Module as it's designed for modules with learnable parameters (e.g. neural networks).. Just create normal functor or function and you should be fine. BTW. If you inherit from it, you should call super().__init__() somewhere in your __init__().. EDIT. Actually inheriting from nn.Module might be a good idea, it allows …
