body: <p>how to add an another hidden layer in this 1 layer model? :</p>
  
  <pre><code>model = nn.Sequential(OrderedDict([ ('fc1', nn.Linear(D_in, H)), 
                                      ('Tanh', nn.Tanh()),
                                      ('fc2', nn.Linear(H, D_out))]))
  </code></pre>
