I’d say “python-ccm” is wrong (not only in using “inputs” but also in its description). The exception are Python *applications*. Those usually have a wrapper to set the PYTHONPATH appropriately. For Python modules we need propagated-inputs for everything that must be available at runtime. ~~ Ricardo
