title: torch version 1.11.0 with cuda can not import torch.nn -> ImportError, not found
body: <p>I currently use the folloing torch versions with CUDA:</p>
  <pre><code>torch                1.11.0+cu113
  torchaudio           0.11.0+cu113
  torchvision          0.12.0+cu113
  
  import torch
  from torch import nn, optim
  import torch.nn.functional as F
  </code></pre>
  <p>This unfortunately leads to an error:</p>
  <pre><code>ImportError: cannot import name 'nn' from 'torch' (unknown location)
  </code></pre>
  <p>Version 1.11 in torch should have torch.nn as the documentation states: <a href="https://pytorch.org/docs/1.11/nn.html" rel="nofollow noreferrer">https://pytorch.org/docs/1.11/nn.html</a></p>
  <p>Can anyone tell me if I am doing something wrong and how to fix it?</p>
