I have run the requirements.txt file, and try to execute the code using your CLI.

But it showed this error
import lib ModuleNotFoundError: No module named 'lib'

I check the source code, there is line of
import lib

What does this lib-library is? Is it your internal library, or dependencies that I need to install?

Update:
I found that you should import it from util.py. The import should be from lib.util import *
