The problem is indeed that lib2to3 fails to load the Grammar.txt file if it is located inside a .zip archive. I think one way to fix it is using of the "get_data" function of the loader https://docs.python.org/3/library/importlib.html#importlib.abc.ResourceLoader.get_data However, this would make caching the Grammar more difficult, as one cannot write back the pickled dict to a zip file Alternatively one could generate an importable *.pyc file from the grammar during the build process
