Python复制在具有自定义__new__方法的类上失败

import copy

class MyClass:
    def __new__(cls, *args, **kwargs):
        # 自定义__new__方法逻辑
        # ...

        # 调用父类的__new__方法创建新对象
        new_obj = super().__new__(cls)

        return new_obj

    def __init__(self, *args, **kwargs):
        # 初始化方法逻辑
        # ...

    def __copy__(self):
        # 创建新对象并复制属性
        new_obj = type(self).__new__(type(self))
        new_obj.__dict__.update(self.__dict__)
        return new_obj

    def __deepcopy__(self, memo):
        # 创建新对象并深度复制属性
        new_obj = type(self).__new__(type(self))
        memo[id(self)] = new_obj
        for key, value in self.__dict__.items():
            setattr(new_obj, key, copy.deepcopy(value, memo))
        return new_obj

# 使用copy模块中的copy函数进行复制操作
original_obj = MyClass()
copied_obj = copy.copy(original_obj)
deep_copied_obj = copy.deepcopy(original_obj)
