Based on a search of the scipy docs, it looks like the function might have moved namespaces from scipy.misc.comb to scipy.special.comb ( https://docs.scipy.org/doc/scipy/reference/generated/scipy.special.comb.html?highlight=comb#scipy-special-comb) when referenced in lmoments3. Alternatively, if you clone the package from the repo directly, it seems to have been addressed in a recent commit: https://github.com/OpenHydrology/lmoments3/commit/3349b90463f649aea02be5dc3726d22e5e500dc3 .
