nosetest: starmodel.obs is None when running self.emcee_p0() #104

While running the first nosetest I got this error:

-------------------- >> begin captured logging << -------------------- root: WARNING: kwarg RA=299.268036 ignored! root: ERROR: single starfit calculation failed for /home/sestovic/anaconda3/envs/isochrones/lib/python3.7/site-packages/isochrones/tests/star1.

Is it possible to use isochrones if we ignore this error, or will it happen every time we try to fit something?

Ah sorry, it's a copy of this: https://github.com/timothydmorton/isochrones/issues/97

Actually I'm still having a problem even after installing MultiNest. I thought it might be the LD_LIBRARY_PATH, since it didn't seem to properly get exported as an environment variable when I put it in .bash_profile. However, even after adding it to .profile, and after manually exporting it (and checking in bash that it's defined correctly), I'm still getting the above error. So I'm not sure what's wrong now.

Okay I realised I forgot to read the last line and install pymultinest. Sorry.
