NotImplementedError: Module [Detect] is missing the required "forward" function

[nassimasad]

"C:\Users\User1\PycharmProjects\pythonProject\venv\Lib\site-packages\torch\nn\modules\module.py", line 352, in _forward_unimplemented
how i can fix please this problem such as i don;t have any class named Detect in the file module.py

Hi @nassimasad ,

Can you share your full code? That would really help in troubleshooting this question.

Otherwise, have you made sure that your torch.nn.Module has a forward() method?

For example:

import torch
import torch.nn as nn
import torch.nn.functional as F

class SimpleNet(nn.Module):
    def __init__(self, input_size, hidden_size, output_size):
        super(SimpleNet, self).__init__()
        self.hidden = nn.Linear(input_size, hidden_size)
        self.output = nn.Linear(hidden_size, output_size)
    
    # Define a forward method
    def forward(self, x):
        x = F.relu(self.hidden(x))
        x = self.output(x)
        return x
