Hi David, thanks for the report. Unfortunately, I cannot tell what the
root error is, because of
https://github.com/numenta/nupic/issues/1815.

If you don't mind doing a little legwork, you might be able to help us
identify the problem.

1. Download our source code by either:
  - git clone https://github.com/numenta/nupic.git
  - or get the tarball at https://github.com/numenta/nupic/archive/master.zip
2. Run the simple hotgym example code:
  - cd nupic/examples/opf/clients/hotgym/simple
  - python hotgym.py

Does this give you any errors?

Thanks,
---------
