title: Internal Server Error due to empty_like method already has a docstring
body: <p>Currently I am facing a problem. Ok let me share it.</p>
  
  <p>I have deployed this project into server <code>(apache2)</code> which is working fine as well as  all operation work successfully. But suddenly it's getting <code>Internal server error</code> basically when login. When I have downloaded the log it shows me <code>RuntimeError: empty_like method already has a docstring</code>. When I again restart my server it's again work smoothly. But I think this need a permanent solution. I also like to share the full trace of the log.</p>
