如何解决属性错误：pymongo中的“ Cursor”对象没有属性“ noCursorTimeout”？

Question

我正在尝试按照MongoDB文档中的此指令在会话中设置noCursorTimeout。但是我得到了错误：AttributeError: 'Cursor' object has no attribute 'noCursorTimeout'

我不知道为什么要得到这个。

from pymongo import MongoClient as Connection
from datetime import datetime

conn = Connection(get_uri())
with conn as conn:
  collection = conn['db_name']['my_collection']
  documents_cursor = collection.find(query).noCursorTimeout() # same with .maxTimeMS()

根据文档，您应该像这样使用它：

cursor = collection.find({"a": 1}, no_cursor_timeout=True)
