title: opcua module in python
body: <p>I currently have Python 2.7.15 installed, and I am trying to import the python opcua module. I am doing this specifically to access the Server method. So far, I have tried two approaches, both which gave the same error that follows.</p>
  
  <p><strong>ImportError: No module named opcua</strong></p>
  
  <p>First approach:</p>
  
  <pre><code>from opcua import Server
  </code></pre>
  
  <p>Second approach:</p>
  
  <pre><code>from __future__import opcua
  </code></pre>
  
  <p>Do I first need to install a separate package before I can use the opcua module?</p>
