    ImportError: 
    Importing the multiarray numpy extension module failed.  Most
    likely you are trying to import a failed build of numpy.
    If you're working with a numpy git repo, try <code>git clean -xdf</code> (removes all
    files not under version control).  Otherwise reinstall numpy.</p>

  <p>Is there any way to select all the libs of conda in a particular environment.
  The only suggestion I got after searching over web is to uninstall anyone.My script is working in python 2.7 and working perfectly with the default python.</p>
