元组长度的对偶问题

我在pydantic(2.0.3版)中有以下模型

from typing import Tuple
from pydantic import BaseModel

class Model(BaseModel):
    test_field: Tuple[int]

但当我进入

model = Model(test_field=(1,2))

我得到错误:

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/code.py", line 90, in runcode
    exec(code, self.locals)
  File "<input>", line 1, in <module>

test_field
  Tuple should have at most 1 item after validation, not 2 [type=too_long, input_value=(1, 2), input_type=tuple]

你知道我该怎么解决吗?
