Try this before we move ahead? There may be a mismatch between your installed nupic version and the code you’re running from the git checkout.

> If you install nupic from binary (pip install nupic), that means you get the latest stable version of NuPIC, which could be days or weeks old. If you want to run unit tests from the source code, make sure that you have checked out proper commit SHA in git to sync the tests with the stable version of NuPIC. For example, if you installed nupic 0.5.7, you should run this command in your git repo before running unit tests: git fetch upstream Where upstream is a remote that points to [https://githu…](https://github.com/numenta/nupic)
