Upgrading to numba 0.16 using pip results in an error

Question

I am working on Ubuntu 14.04 and I have numba 0.15 working fine.

I ran:

pip install --user --upgrade numba

to upgrade to numba 0.16, but now when I try to import numba, I get the following error:

~/.local/lib/python2.7/site-packages/numba/__init__.py in <module>()
      4 from __future__ import print_function, division, absolute_import
      5 import re

      7 from ._version import get_versions
      8 from . import special, types, config

      6 import llvmlite.llvmpy.ee as le
      7 import llvmlite.binding as ll

ImportError: No module named llvmlite.llvmpy.core

This is very strange because I found this:

Q: Do I need to delete or update llvmpy?

A: No, Numba no longer uses llvmpy.

any ideas?
