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:

這裏有什麼問題嗎?
