could not register token: [Errno 111] Connection refused

Running the example on a local anaconda version of jupyter I get this error: could not register token: [Errno 111] Connection refused

Running this from a jupyter notebook with sudo: sudo jupyter notebook --allow-root

Fixes the issue, but this only works if you have jupyter installed on root (which is not a reasonable solution for servers, etc).
