ImportError pymc on Anaconda/Mac OS X

[adakite]

Hi,

I have anaconda (up-to-date) on my Mac running the very last OS X (10.11.4) and up to now I never had any issues with packages installation but for PyMC.

While installation ran smoothly, I cannot use it as while importing I got:

----> 8 import numpy, pymc
      9 
     10 # create some test data

Any idea how to fix that?

Thank you

Ddi you install this via pip or conda?

I used conda, should I try pip?

I did reinstall everything (including my anaconda distrib') and this is now working! Don't know what happened.
