Htmresearch failing tests

Engineering NuPIC
1

I am trying to install htmresearch in order to replicate your the results on your most recent paper titled “Why Does the Neocortex Have Layers and Columns, A Theory of Learning the 3D Structure of the World.” After running tests I get a module import error:
ImportError: No module named htmresearch_core.experimental

Has this module been removed from htmresearch?

So you are following this?

Are you sure you have the latest htmresearch code installed?

The htmresearch-core installation instructions are currently only available in @lscheinkman’s comment here: Where is the sensorimotor code?. The htmresearch and htmresearch-core READMEs are not up-to-date. I’ll add @lscheinkman’s instructions to the READMEs.

The htmpapers repo does not support pip install of htmresearch yet. We’re planning on adding that.

Yes and yes. I am following explanations in the above two links. I get the following error after attempting to import ApicalTiebreakTemporalMemory

ImportError: No module named apical_tiebreak_temporal_memory

I also run the tests and, according to my understanding, I get errors caused by

ImportError: No module named htmresearch_core.experimental

The htmresearch-core repository is giving instructions for installing nupic.core not htmresearch-core.

6

It was originally a fork of nupic.core, and the README was never updated. I think @mrcslws is working on updating the readme with installation instructions he linked to above. Can you try those?

7

Done. You should now be able to run the code by following instructions in the htmresearch and htmresearch-core READMEs.

Thanks! Installed htmresearch-core and htmresearch now.
