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.
