Regex ERROR: regex._regex_core.error: bad escape \d at position 7

Hi,

I got this error while trying to run extractor:

Code:

import requests
from extractnet import Extractor

raw_html = requests.get('https://apnews.com/article/6e58b5742b36e3de53298cf73fbfdf48').text
results = Extractor().extract(raw_html)
for key, value in results.items():
    print(key)
    print(value)
    print('------------')

Traceback:

regex._regex_core.error: bad escape \d at position 7

I was able to make it work by replacing pattern definition in locale.py -> _generate_relative_translations:

Was (this produces the error):

pattern = DIGIT_GROUP_PATTERN.sub(r'?P<n>\d+', pattern)

Changed to (this works fine):

pattern = DIGIT_GROUP_PATTERN.sub(r'?P<n>\g<0>', pattern)

Could this be a python version issue?

I use Python 3.8.10.

It is dateparser issue
