안녕하세요 강사님

RuntimeError: populate() isn't reentrant

에러관련해서 검색을 해봤더니, 환경 by 환경의 문제 같더라구요 ㅠㅠ 핵심을 잘 못짚겠어서 고치질 못하기에

여태 주피터 노트북 활용하는 강의는 따라하질 못하고 막혀있는데요.

어떻게 해결하면 될까요?

#1 이게 제 코드구여

import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'instagram.settings'
# os.environ["DJANGO_ALLOW_UNSAFE"] = 'true'
os.environ['DJANGO_ALLOW_ASYNC_UNSAFE'] = 'true'

import django
django.setup()

#2 이게 에러 메세지 이구요

이에 따라서 에러메세지에 표시된 경로에 위치한 init.py 파일 내용입니다.

from django.utils.version import get_version

VERSION = (4, 1, 1, "final", 0)

__version__ = get_version(VERSION)
