Python amateur here. I installed piston-cli, but when I try to run it I get an error

Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/runpy.py", line 184, in _run_module_as_main
"main", mod_spec)
File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/runpy.py", line 85, in _run_code
exec(code, run_globals)
File "pistoncli/main.py", line 30, in module
from .ui import (
SystemError: Parent module '' not loaded, cannot perform relative import

Can you help with this? Or do you know where I can find help? I've been searching posts on Steemit and this one is the best I was able to find.

Thank you

Thanks!
