我正在尝试使解析器使用beautifulSoup和多处理.我有一个错误:

RecursionError:超出最大递归深度

我的代码是:

import bs4, requests, time
from multiprocessing.pool import Pool

html = requests.get('https://www.avito.ru/moskva/avtomobili/bmw/x6?sgtd=5&radius=0')
soup = bs4.BeautifulSoup(html.text, "html.parser")

divList = soup.find_all("div", {'class': 'item_table-header'})


def new_check():
    with Pool() as pool:
        pool.map(get_info, divList)

def get_info(each):
   pass

if __name__ == '__main__':
    new_check()

为什么我会收到此错误以及如何解决？

更新: 错误的所有文本是

Traceback (most recent call last):
  File "C:/Users/eugen/PycharmProjects/avito/main.py", line 73, in <module> new_check()
  File "C:/Users/eugen/PycharmProjects/avito/main.py", line 67, in new_check

此代码正在更改类中所有 CharField 的大小。如何更改一个 CharField 的大小？

formfield_overrides = {
    models.CharField: {'widget': TextInput(attrs={'size': '20'})},
}
