Annotating dependecies for very long sentences

After hours of trial and error, I managed to install Prodigy on my macbook. But now I am lost. I got "No module named prodigy"

Adrianas-MacBook-Pro:~ ariadna$ python3 -m prodigy
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/runpy.py", line 188, in _run_module_as_main
mod_name, mod_spec, code = _get_module_details(mod_name, _Error)
File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/runpy.py", line 147, in _get_module_details
return _get_module_details(pkg_main_name, error)
File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/runpy.py", line 111, in _get_module_details

File "/Users/ariadna/Library/Python/3.9/lib/python/site-packages/prodigy/init.py", line 1, in
from .util import init_package
ModuleNotFoundError: No module named 'prodigy.util'

Besides that, how do I get to an interface? Tks for any help.
