title: ImportError: No module named skimage.io
body: <p>I have already installed my scikit-image on my following path: </p>
  
  <pre><code>Requirement already satisfied: scikit-image in /usr/local/lib/python3.6/site-packages (0.14.0)
  </code></pre>
  
  <p>This is what I can get when I type <code>pip install scikit-image</code> on my mac terminal</p>
  
  <p>However, whenever I run the following:</p>
  
  <pre><code>import skimage.io as io
  </code></pre>
  
  <p>It keeps returning error as below :</p>
  
  <pre><code>ImportError: No module named skimage.io
  </code></pre>
  
  <p>What would be the cause of this import failure?</p>
