Segmentation Fault on Mac OS X

When I run NAB run.py, I get a segmentation fault with code 11. I installed NAB and Nupic using pyenv after a lot of problems with conda. Here's the basic information, happy to provide more as necessary.

I do not think pip install nupic works on the latest versions of High Sierra. See numenta/nupic-legacy#3851.

To run NuPIC you may need to compile it locally. See the README for instructions.

Thanks, that worked. I used pyenv shell 2.7, cloned the NuPIC repo, used pip install . in nupic, and then used pip install . --user in NAB.
