title: scikit learn 0.18.1: 'module' object has no attribute 'neural_network'
body: <p>Hi I am trying to use MLP</p>
  
  <pre><code>import numpy as np
  import sklearn as sk
  
  X = [[0., 0.], [1., 1.]]
  
  Y = [[1.1, 1.1], [2.1, 2.1]]
  
  reg = sk.neural_network.MLPRegressor(solver='lbfgs', alpha=1e-5, hidden_layer_sizes=(5, 2), random_state=1)
  </code></pre>
  
  <p>I thought neural network is available for 0.18.1 but I am getting the following error:</p>
  
  <pre><code>AttributeError: 'module' object has no attribute 'neural_network'
  </code></pre>
