title: Python 3: No module named 'sklearn.model_selection'
body: <p>I am trying to learn Neural Networks via the Keras Deep Learning Library in Python.  I am using Python 3 and referencing this link: <a href="http://machinelearningmastery.com/regression-tutorial-keras-deep-learning-library-python/" rel="noreferrer">Tutorial Link</a>   </p>
  
  <p>I try to run the code below but get the following error:  </p>
  
  <p>ImportError: No module named 'sklearn.model_selection'</p>
  
  <pre><code>import numpy
  import pandas
  
  from keras.models import Sequential
  from keras.layers import Dense
  from keras.wrappers.scikit_learn import KerasRegressor
  from sklearn.model_selection import cross_val_score
  from sklearn.model_selection import KFold
  from sklearn.preprocessing import StandardScaler
  from sklearn.pipeline import Pipeline
  </code></pre>
  
  <p>Any help is greatly appreciated!  </p>
