Hi folks.

Does there exist a pure python version of NuPIC? Or do they all require C++? I’ve seen reports that yes, there is one, but then when I try to track it down I don’t find anything.

Thanks!

There is [ZHTM](https://discourse.numenta.org/t/yet-another-yet-another-htm-implementation/4831) written in pure python. But NuPIC/HTM.core requires C++.
