从pydantic 文档中我明白了这一点：

import pydantic

class User(pydantic.BaseModel):
    id: int
    name: str

class Student(pydantic.BaseModel):
    semester: int

# this works as expected
class Student_User(User, Student):
    building: str

print(Student_User.__fields__.keys())
#> dict_keys(['semester', 'id', 'name', 'building'])

但是，当我想动态创建类似的对象时（遵循动态模型创建部分）：

# this results in a TypeError
pydantic.create_model("Student_User2", __base__=(User, Student))

我得到：

TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases

问题：如何动态创建一个类Student_User
