title: expected np.ndarray (got DataFrame)
body: <p>I wanted to find out the output_size of a convolution operation, but I am strugglin with converting my dataframe into a tensor.</p>
  <pre class="lang-py prettyprint-override"><code>output_size = torch.nn.Conv2d(3, 5, 5,stride=1, padding=3,    
                  dilation=1, groups=1, bias=True, padding_mode='zeros')
  
  fashion = torch.from_numpy(load_fashion)
  input_ = torch.Tensor((fashion.values), dtype=torch.float)  
  
  
  output = output_size(input_)
  </code></pre>
