title: ModuleNotFoundError: No module named 'bigchaindb_driver'
body: <p>I'm using Django with Python 3.6.3 and Windows 7. I'm trying to install BigchainDB driver and want to use IPDB.
  I run this <code>pip install bigchaindb</code> and I guess it executed successfully.
  I import bigchaindb_driver like that <code>from bigchaindb_driver import BigchainDB</code>. But when i run the server using <code>python manage.py runserver</code> it gives me this error.
  <strong>ModuleNotFoundError: No module named 'bigchaindb_driver'</strong></p>
  
  <p>My code look like this:</p>
  
  <blockquote>
  <pre><code>import os
  from bigchaindb_driver import BigchainDB&gt; 
  tokens = {}
  tokens['app_id'] = 'my-app-id'
  tokens['app_key'] = 'my-apy-key'
  bdb = BigchainDB('https://test.ipdb.io', headers=tokens)
  </code></pre>
  </blockquote>
  
  <p>My questions are:</p>
  
  <ul>
  <li>If i want to use IPDB, i still have to install bigchainDB on my local machine?</li>
  <li>What exactly i need to start a project on bigchainDB, as i have installed MongoDB and RethinkDB but i don't exactly know weather i need them or not.</li>
  </ul>
