Unless you have a very specific plan, I would advise against this.
Sound applications of machine learning are time-consuming, and Tor's
setting is particularly difficult to tackle as a large fraction of a
relay's information (e.g., nicknames, port numbers, bandwidth values)
are controlled by an adversary.

Sounds great.  I would also really like exitmap to be
Python 3-compatible.

For now, exitmap only supports Python 2 although there's probably not
much that prevents it from being Python 3-compatible.

This assumption should be made explicit, so I replaced all
"#!/usr/bin/env python" lines with "#!/usr/bin/env python2" in commit
a4dccea.  Thanks for pointing this out.

Personally, I don't feel strongly either way as long as they are
written.

I think we can decide case by case if we want to rely on a new library.
