title: Getting UnparsedFlagAccessError when trying to import glog in python
body: <p>I am trying to use glog in my python code and when I am trying to import, it throws the following error:</p>
  
  <pre><code>/usr/local/lib/python2.7/dist-packages/glog.py:171: RuntimeWarning: 
  Trying to access flag verbosity before flags were parsed. This will raise 
  an exception in the future.

  </code></pre>
  
  <p>My code is as follows.</p>
  
  <pre><code>import gflags 
  import glog as log
  </code></pre>
  
  <p>I have searched online but haven't got any information about the python version of glog. I think this error has to do something with gflags and glog together. Can anyone please explain what is going wrong ?</p>
