我不知道为什么，但是每当我尝试传递给共享对象共享自定义类对象的方法时，我都会收到这个奇怪的错误。Python版本：3.6.3

代码：

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

错误：
