Python Celery worker_main "RuntimeError：最大再帰深度を超えました"

Question

私はCeleryベースのアプリケーションで作業しており、main関数内から作業者を開始したいと考えています。ここでは、コードの非常に単純化されたバージョンは次のとおりです。

from celery import Celery 

class CoolApp(object): 
    def __init__(self): 
     self.app = Celery('test', 'amqp://guest@localhost/') 

test = CoolApp() 

test.app.worker_main() 

これはRuntimeError: maximum recursion depth exceeded in cmpエラーを生成し、私は理由を理解することはできません。助けてください。

私は4.1.0にセロリ3.1.25にアップグレードしようとしたとき、私は同じエラーを得ました。 基本的に4.1.0では、パッケージのいくつかは非難されました。そのため、最新バージョンでは廃止されているクラスを使用していないことを確認してください。 私の場合は、3.1.25で非推奨となり、今では私は、これはあなたを助けることを願っていますcelery.worker.request.Request

ですcelery.worker.job.Requestを使用しています。
