title: Python: cannot import name 'rgb2gray' from 'skimage.color'
body: <p>When I try: </p>
  
  <pre><code>&gt;&gt;&gt; from skimage import io
  </code></pre>
  
  <p>I get at the end the following: </p>
  
  <pre><code>from ..color import rgb2gray
  ImportError: cannot import name 'rgb2gray' from 'skimage.color' (C:\Users\user\A
  ppData\Local\Programs\Python\Python37-32\lib\site-packages\skimage\color\__init_
  _.py)
  </code></pre>
  
  <p>Although I have installed the packages: matplotlib, scipy, pillow, numpy and six</p>
  
  <p>How can I fix it? Any help would be appreciated</p>
