Hi all,
I followed the instructions for installing Nupic on Ubuntu (https://github.com/numenta/nupic/wiki/Installing-NuPIC-on-Ubuntu) and ran into a couple of issues which I resolved by setting up the PYTHONPATH, NUPIC, and NTA environment variables.
However, I eventually got stuck when running the Python tests and here is what I'm getting:
tests/unit/py2/nupic/engine/network_test.py:32: NetworkTest.testErrorHandling FAILED

Was wondering if anybody has any solution for this issue. My Python version is 2.7 could that be the source of problem? In other words does Nupic strictly require Python 2.6 or it's fine with 2.7 too?
