Did you install multinest/pymultinest?

ggonzo47 commented 5 years ago

No. I wanted to pass the first nosetests before trying to install multinest.

timothydmorton commented 5 years ago

Yes; I should probably mention in the docs that those particular tests currently fail without multinest. (Or I could correct them... I'll leave this issue open to remind me; thanks!)
