Error running hierarchy_network_demo.py

Engineering NuPIC
1

I am running NuPIC in a Docker container on a MacBook. When I run the stock file hierarchy_network_demo.py, I get the following error before it is able to write the .csv:

Writing output to: hierarchy-demo-output.csv
Traceback (most recent call last):

KeyError: 'categoryIn'

I can run the other python files in the directory; I have run network_api_demo.py many times and it creates the 2000-line .csv file as expected.

Any clues from the error messages above? Thank you in advance. I have already pulled the latest NuPIC image and confirmed the same error.

I get the same error from a fresh installation on OS X.

@Containerhouse Can you create an issue about this and I’ll triage it?
