ModuleNotFoundError: No module named 'wfpt'

This is the error when I import hssm 0.2.0. However, there's no module named wfpt. What is that?

Hi @suwangcn, thank you for trying HSSM,

The import of the wfpt module is from the hddm-wfpt package, which is a dependency of HSSM. It hosts a blackbox version of the likelihood computations for the ddm and full_ddm models. Could you give a bit more information about your setup and how you installed HSSM?
