Problem running category_prediction example

[alanbernstein]

I'm trying to use this for the first time. I can pip install nupic with no trouble, but when I try python examples/prediction/category_prediction/run.py, I get this:

Traceback (most recent call last):

I found a couple references to a "Duplicate ID" failure, but not in this context.

OSX 10.12.6, python 2.7.13

This example seems to be running fine for me. Can you try this:

• uninstall nupic completely
• reinstall using pip install nupic and save the console output
• show us the versions of nupic that were installed
• paste the installation logs here

There seems to be some unrelated problem with my python installation, I don't think it will be useful to discuss that here.

I tried installing nupic in a virtual environment, and had no trouble running the example in that context.
