    pattern = (
        "([" + consonants + "]+)?"  # capture one or more, optional
        "([" + vowels + "])"  # capture at least one vowel
        "(.*)"  # capture zero or more of anything

The reason is that you have an old version of attrs installed. Could you try pip show attrs and paste the output?

I don't why it happens because in pyproject.toml, it specifies that attrs needs to be >= 20.0. So maybe uninstall and reinstall cyberbrain will solve this problem.

[javacoffer2020]

Thank you for your response! I have upgraded attrs to 20.3.0. And now Cyberbrain is worked. Maybe, old version attrs is required by another package, so new version couldn't be auto installed when I pip install cyberbrain (maybe I should use --user when I installed Cyberbrain ). Finally, I upgraded it manually.

Great! Theoretically it installing cyberbrain should upgrade its dependencies, but since you're using Conda and I'm not very familiar with it, it may happen.
