I’m watching [https://www.youtube.com/watch?v=Sirm-xFPiOA](https://www.youtube.com/watch?v=Sirm-xFPiOA)

is there a standalone generalized SDR python package?

It seems like SDR’s are a datatype that have specific functions associated with them and I was thinking, ‘wouldn’t it be great if there was a package that would allow me to easily create, mutate, compare, etc SDRs, then I could get more of a feel for their power and properties’

So does one already exist as part of the Nupic code base that I could use? if so where is it and where is the documentation for it?

Nothing in python, but here are some tools I wrote for those visuals in JavaScript.

I thoguht Nupic was written in python, for SDRs does it just pass around raw numpy ndarrays then?
