I am having problems installing NuPIC on Ubuntu 16.04 LTS. Installation appears ok:

pip install . --user

After running tests with python scripts/run_nupic_tests.py get this output (meaning the installation is ok):
==== 711 passed, 17 skipped, 8 xfailed, 5 pytest-warnings in 415.27 seconds ====

However, after running network example I get the following error:

    /opt/nupic$ python examples/network/network_api_demo.py 
    WARN:   PyRegion::createSpec failed: 0x7ffeeb54be90
    Traceback (most recent call last):

        network = createNetwork(dataSource)
      File "examples/network/network_api_demo.py", line 144, in createNetwork
        json.dumps({}))
      File "/usr/local/lib/python2.7/dist-packages/nupic/engine/__init__.py", line 639, in addRegion

        return _engine_internal.Network_addRegion(self, *args, **kwargs)
    ImportError: No module named AnomalyLikelihoodRegion

The same error happens if I install with sudo. It also occurs on both of my machines. Do you have any ideas of what the culprit is? Thanks!

There is something wrong with this demo. I’ll look into it. In the meantime, run this demo:

python docs/examples/network/complete-network-example.py

This is the same code in the network quickstart docs.

The latter test did work. Thanks for a quick reply!
