class BaseApiOut(GenericModel, Generic[_T], BaseApiSchema):TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases

今天迁移到新服务器，跑程序报错：class BaseApiOut(GenericModel, Generic[_T], BaseApiSchema):TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases
请问大佬有没有遇到这个问题，如何解决，请指教，谢谢
