PyTorch NotImplementedError in forward

Question

import torch
import torch.nn as nn

device = torch.device(\'cuda\' if torch.cuda.is_available() else 
\'cpu\')

class Model(nn.Module):
    def __init__(self):
              


        

Answer 1

please look carefully at the indentation of your __init__ function: your forward is part of __init__ not part of your module.

Answer 2

This error happens when you don't implement the required method from super class, in my case, i had typo on the function name forward. I recommend you check your code indentation.
