ImportError: No module named date_capnp

Question

While trying to understand nupic minecraft demo code. I am running nupic_client.py from pycharm IDE. Python version is 2.7.8 on Mac OS with nupic dowloaded as package version 0.2.8

On running nupic_client.py following error occurs ImportError: No module named date_capnp

Any help is appreciated.

I believe you mean nupic==0.2.3, since 0.2.8 isn't out yet. This should be fixed with https://github.com/numenta/nupic/pull/2231. More details are available in the issue you referenced (the direct link is https://github.com/numenta/nupic/issues/2166). Hope this helps!

EDIT This should now be resolved in nupic==0.2.6
