Numba Runtime Linking Error

Question

I'm trying to import numba. I installed llvmlite and numba using the instructions found here (https://github.com/numba/numba#custom-python-environments) however I get the following error when import numba.

Traceback (most recent call last):
  File "kayhan.py", line 6, in <module>
    from numba import *

I had a similar issue with llvm 3.6 on Ubuntu 14.04. Try:

apt-get install gcc-4.8 g++-4.8 libedit-dev llvm-3.6-dev
LLVM_CONFIG=/usr/lib/llvm-3.6/bin/llvm-config CC=/usr/bin/gcc-4.8 CXX=/usr/bin/g++-4.8 pip install numba
