‘clonify’ package needs python 2.7 but ‘biopython’ requires python 3

[ponomarevsy]

Looks like ‘clonify’ package needs python 2.7, at the same time, its dependency, ‘biopython’, requires python 3. If I don’t upgrade python, then, ‘biopython’ doesn’t get installed, and, if I upgrade python (to v3), then, ‘biopython’ gets installed but ‘clonify’ complains:
