我有一个包含几个np.array的类：

class VECMParams(ModelParams):
    def __init__(
        self,
        ecm_gamma: np.ndarray,
        ecm_mu: Optional[np.ndarray],
        ecm_lambda: np.ndarray,
        ecm_beta: np.ndarray,
        intercept_coint: bool,
    ):
        self.ecm_gamma = ecm_gamma 
        self.ecm_mu = ecm_mu
        self.ecm_lambda = ecm_lambda 
        self.ecm_beta = ecm_beta
        self.intercept_coint = intercept_coint

我想重写==操作符，基本上，当所有数组都等于rhs 1时，VECMParam等于另一个：

def __eq__(self, rhs: object) -> bool:
    if not isinstance(rhs, VECMParams):
        raise NotImplementedError()

    return (
        np.all(self.ecm_gamma == rhs.ecm_gamma) and
        np.all(self.ecm_mu == rhs.ecm_mu) and
        np.all(self.ecm_lambda == rhs.ecm_lambda) and
        np.all(self.ecm_beta == rhs.ecm_beta) 
    )

尽管如此，mypy还是一直说Incompatible return value type (got "Union[bool_, bool]", expected "bool") [return-value]，因为np.all返回bool_，而__eq__需要返回本机bool。我搜索了几个小时，看起来没有办法将这些bool_转换为本机bool。有人遇到同样的问题吗？
PS：执行my_bool_ is True未计算为正确的本机bool值
