Looks like there's currently a type conversion issue where newer version of pandas expect categorical types and rpy2 may not automatically convert them. Keeping note of the error here to revisit in the future. For now we're fixing the pandas requirement to version 0.23.4

TypeError: Parameter 'categories' must be list-like, was <rpy2.rinterface.StrSexpVector - Python:0x7fca505dcd38 / R:0x564cb91259a8>

Occurs at self.marginal_estimates = pandas2ri.ri2py(base.summary(res)[0]) in Lmer.post_hoc
