import pymongo
myclient = pymongo.MongoClient(host='localhost', port=27017)

在本地已经启动了 mongod 服务,使用其他工具可以连接上数据库。

执行了上面的两行代码后,出现了下面的报错信息

Exception in thread pymongo_server_monitor_thread:

python 连接 mongodb 时出现运行错误?

大概是说 pymongo_server_monitor_thread 线程出现了异常,查了一下类似的问题,有的说是线程数太多,有的说是内存不足。但是我只执行了以上两行代码,内存也没发现什么飙升的情况。

这是什么原因导致的?
Python 3.12.0
pymongo 4.6.1
mongodb 7.0.4
