如何避免芹菜自动测定忽略信号？

Question

我想在task（）decorator中向autoretry_for参数传递一个异常元组，但是当引发异常时，不会重试，而是会显示一条消息If Ignore signal occures task shouldn't be retried

这是一个简化的代码示例，本应触发无限次重试，但实际上并非如此。我错过了什么

import myapp.celery as celery


@celery.app.task(autoretry_for=(Exception,))
def metphods():
    print("Hello")
    p = 1/0

然后我运行函数，但没有重试

methods()
Hello
