我正在尝试编写一个将 numpy 数组(或任何任意对象(传递给工人的芹菜应用程序。据我所知，这需要通过pickle进行序列化(注意：我知道安全隐患，但在这种情况下这不是问题(。
但是，即使尝试了所有可能的方法来允许泡菜作为序列化程序，我仍然收到以下 kombu 异常：
kombu.exceptions.ContentDisallowed: Refusing to deserialize untrusted
content of type pickle (application/x-python-serialize)
我当前的文件目前是：
# tasks.py
from celery import Celery
app = Celery(
'tasks',
broker='redis://localhost',
accept_content=['pickle'],
task_serializer='pickle'
)
@app.task
def adding(x, y):
return x + y
if __name__ == '__main__':
import numpy as np
adding.apply_async((np.array([1]), np.array([1])), serializer='pickle')
另外我还有一个配置文件：
# celeryconfig.py
print('configuring...')
accept_content = ['pickle', 'application/x-python-serialize']
task_serializer = 'pickle'
result_serializer = 'pickle'
from kombu import serialization
serialization.register_pickle()
serialization.enable_insecure_serializers()
但是，如果我运行工作线程(celery -A tasks worker --loglevel=info(，然后执行进行异步调用的代码(python tasks.py(，我会得到以下回溯。我错过了什么吗？

对于任何遇到这个问题的人：
答案是使用app.config_from_object方法：
import celeryconfig
app.config_from_object(celeryconfig)
