title: How to install opencv library in python 3.5?
body: <p>I've created a project in Pycharm IDE. I've used python 3.5, <code>tensorflow</code> library. Now I want to install <code>opencv</code> in this. <br>
  I have tried so many videos available on youtube and some tutorials in the internet. But when import open cv in python shell it gives me following error. How can I fix it?<br>
  <strong>import code</strong></p>
  
  <pre><code>import cv2           
  </code></pre>
  
  <p><strong>Error message</strong>       </p>
  
  <blockquote>
    <p>Traceback (most recent call last):
      File "", line 1, in 
        import cv2
    ImportError: Module use of python27.dll conflicts with this version of Python.       </p>
  </blockquote>
  
  <p>I have noticed that <strong>python 2.7 is used to install opencv</strong>. Is it a must o use 2.7 version?<br>
  Also as I know <strong>tensorflow will not support if I use another version of python(other than 3.5)</strong> </p>
