我不知道爲什麼,但每當我嘗試傳遞給共享對象共享自定義類對象的方法時,我都會得到這個奇怪的錯誤。 Python版本:3.6.3多處理管理器和自定義類

代碼:

from multiprocessing.managers import SyncManager 

class MyManager(SyncManager): pass 
class MyClass: pass 

class Wrapper: 
    def set(self, ent): 
     self.ent = ent 

MyManager.register('MyClass', MyClass) 
MyManager.register('Wrapper', Wrapper) 

if __name__ == '__main__': 
    manager = MyManager() 
    manager.start() 

    try: 
     obj = manager.MyClass() 
     lst = manager.list([1,2,3]) 

     collection = manager.Wrapper() 
     collection.set(lst) # executed fine 
     collection.set(obj) # raises error 
    except Exception as e: 
     raise 

錯誤:

--------------------------------------------------------------------------- 
Traceback (most recent call last): 
    File "D:\Program Files\Python363\lib\multiprocessing\managers.py", line 228, in serve_client 
    request = recv()

    return func(token, serializer, incref=incref, **kwds) 
TypeError: AutoProxy() got an unexpected keyword argument 'manager_owned'

這裏有什麼問題嗎?

發現臨時解決方案here。 我設法通過在AutoProxy的初始化程序中添加所需的關鍵字來修復它,在multiprocessing \ managers.py雖然,我不知道這個kwarg是否對任何事情負責。
