@codedhard So when you change back to 'implementation': 'cpp' it works fine?

Why do you want to use the python implementation (just curious)?

[codedhard]

@rhyolight No does not work with 'implementation': 'cpp' the result is "Killed" and nothing more.

Just for debugging purpose because the other implementation was not giving any "errors" other then "Killed".

[rhyolight]

@codedhard Can you provide more info about the problem when using cpp?

• operating system
• NuPIC installation method (pip install or local compile?)
• exact command you are running and the exact console output.

Thanks.

This is a nupic.core issue somewhere within the engine region interface. Same occurs with py and cpp CLA Classifier factory output. Without recreating a C++ version of the hierarchy_network_demo it's tricky to work out in PyCharm what happens in the Core. The simplest way to recreate can be;

Spin up a new Ubuntu 14.02 (LTS) VM. It comes with Python 2.7.6 and GCC 4.8.x

Add Python dependencies

• sudo apt-get build-dep python2.7

Pip not installed.. following installs 1.5.4

• sudo apt-get install python-pip
• pip list shows wheel==0.24.0

pip install numpy fails (no Python.h) needs;

• sudo apt-get install python-dev then;
• sudo pip install numpy (installs 1.10.1)

Install bindings and nupic (sudo added to get around permissions)

• sudo pip install https://s3-us-west-2.amazonaws.com/artifacts.numenta.org/numenta/nupic.core/releases/nupic.bindings/nupic.bindings-0.2.2-cp27-none-linux_x86_64.whl
• sudo pip install nupic
• sudo apt-get install git
• git clone https://github.com/numenta/nupic.git
• cd nupic
• python examples/network/hierarchy_network_demo.py

I got the exactly same issue when using SDRCategoryEncoder :( BTW, I'm using docker version nupic
