Warning/Error with ipython hanging, solved by installing directly from github

[nickp60]

Hi Sourcetracker2 team. Would it be possible to make a new release, and update the version of Sourcetracker2 available on pip? It appears that there have been some changes that break the version installable via pip ( 2.0.1 ). Potentially related to ipython/ipyparallel#303

I installed the software as described in the readme, and ran the following

$ sourcetracker2 gibbs -i genus.txt -m map.txt -o example1/ --jobs 8
/Users/nwaters/miniconda3/envs/st2/lib/python3.5/site-packages/ipyparallel/util.py:214: RuntimeWarning: IPython could not determine IPs for LSKI3305: [Errno 8] nodename nor servname provided, or not known
  RuntimeWarning)

... which hangs indefinitely, no cpu load that I could see in each of the spawned ipyparallel jobs.

Here is my conda env:

When installing from git (pip uninstall sourcetracker && pip install git+https://github.com/biota/sourcetracker2.git)
the same command works, presumably due to the switch from to python's multiprocessing library. Hope that helps someone out there.
