Could not import cmaps

[thelightonmyway]

I've installed the cmaps, which's version is 2.0.1, and my python's version is 3.10.14. However, I'm facing the problem that I could not import it, which shows: 'ImportError: attempted relative import with no known parent package'. Is this problem because the python and cmaps versions are not compatible? How could I resolve it?

Thanks, sincerely.
