title: Tensorflow: No module named contrib.learn.python.learn.datasets.mnist
body: <pre><code>import tensorflow as tf
  from tensorflow.contrib.learn.python.learn.datasets.mnist import read_data_sets
  </code></pre>
  
  <p>I tried executing the above and I am getting the below error:</p>
  
  <pre><code>ImportError: No module named contrib.learn.python.learn.datasets.mnist
  </code></pre>
  
  <p>I did <code>sudo pip show tensorflow</code>.
  The location showed <code>/usr/local/lib/python2.7/dist-packages</code></p>
  
  <p>So, I appended /usr/local/lib/python2.7/dist-packages to sys.path. But still getting the same error.</p>
  
  <p>I'm not able to use anything from contrib.</p>
  
  <p><code>training_set = tf.contrib.learn.datasets.base.load_csv(filename=IRIS_TRAINING, target_dtype=np.int)</code></p>
  
  <p><code>AttributeError: 'module' object has no attribute 'contrib'</code></p>
  
  <p>Could somebody please help me? Thanks in advance.</p>
