Readme example

I'm trying to just run the example in the readme and get the following error:

$ python pyhsmm/examples/hsmm.py
/usr/local/lib/python2.7/site-packages/pybasicbayes/distributions/multinomial.py:21: UserWarning: using slow sample_crp_tablecounts
  warn('using slow sample_crp_tablecounts')
/usr/local/lib/python2.7/site-packages/pybasicbayes/distributions/negativebinomial.py:25: UserWarning: using slow sample_crp_tablecounts
  warn('using slow sample_crp_tablecounts')
/usr/local/lib/python2.7/site-packages/pyhsmm/internals/transitions.py:17: UserWarning: using slow transition counting
  warn('using slow transition counting')

This demo shows the HDP-HSMM in action. Its iterations are slower than those for
the (Sticky-)HDP-HMM, but explicit duration modeling can be a big advantage for
conditioning the prior or for discovering structure in data.

On OSX 10.12.4 with python 2.7.11. I tried building from source and using the pip install and both give the same error.

Got it! I recently upgraded to 10.12.x and it reset my gcc symlink back to clang. Also needed to pip install -e . from source.

I have the same problem on Win10 with python 3.5
