import oa and got error "re.error: incomplete escape \U at position 2"

Hi I'm trying to use the oa lib with python 3.9 on windows10 I generated a clean project: python -m venv _venv

And I activated it: _venv\Scripts\activate.bat

I've checked the status of the lib:

(_venv) C:\Users\Amministratore\PycharmProjects\dev>pip show oa
Name: oa
Version: 0.1.0
Summary: Python interface to OpenAi
Home-page: https://github.com/thorwhalen/oa

License: apache-2.0
Location: c:\users\amministratore\pycharmprojects\dev\_venv\lib\site-packages
Requires: config2py, dol, graze, i2, jsonref, openai
Required-by:

But when i open a python shell and make import oa, I got this error:

Why?

Hi @StefanoGITA. I just looked into it for the last 45mn, but couldn't reproduce on my side -- probably due to the fact that I'm on a Mac machine, and what you're having is a windows-specific issue.

Test run fine both on Mac (my local) and linux (remote CI), but I don't have access to a windows machine to dig into it further. If you're interested, you can look into it yourself, and I can assist you. We could even do this over a screen-share session.

What I can tell you is it comes from config2py trying to make a "local file store" (using dol.TextFiles(config_src), and this errs when trying to make a regular expression using the string that dol.naming.template_to_pattern makes. But can't see what that string is from the traceback.

I'm the main author of config2py and dol, so I should be able to help.
