当我尝试将列表传递给我的 class 属性时发生错误

Question

我正在尝试使用 class 方法将列表传递到我的 class 属性：

class BASE_MODEL(object):
    def __init__(self, train_data, train_labels, val_data, val_labels):
        self.train_data, self.train_labels, self.val_data, self.val_labels = \
            train_data, train_labels, val_data, val_labels

    @classmethod
    def list_to_data(cls, data_list):
        train_data, train_labels, val_data, val_labels = data_list
        data = cls(train_data, train_labels, val_data, val_labels)
        return data

class Fine_Tune_Model(BASE_MODEL):
    def __init__(self, fine_tune_at=None):
        super(BASE_MODEL, self).__init__()
        self.fine_tune_at = fine_tune_at

fine_tune_model = Fine_Tune_Model.list_to_data(data_lsit)

超级class。

然而，当我尝试将相同的函数传递给子程序时class，出现错误：

Traceback (most recent call last):
  File "E:/Studium/Thesis/Fine_Tuning.py", line 138, in <module>
    main()
  File "E:/Studium/Thesis/Fine_Tuning.py", line 133, in main
    fine_tune_model = Fine_Tune_Model.list_to_data(create_data.split_data(3000, 200))
  File "E:\Studium\Thesis\Train.py", line 32, in list_to_data
    data = cls(train_data, train_labels, val_data, val_labels)
TypeError: __init__() takes from 1 to 2 positional arguments but 5 were given

Process finished with exit code 1

是不是因为我的subclass多了一个参数'fine_tune_at'？如果是这样，我该如何避免这个问题？

我找到问题所在了：

class BASE_MODEL(object):
    def __init__(self, train_data, train_labels, val_data, val_labels):
        self.train_data, self.train_labels, self.val_data, self.val_labels = \
            train_data, train_labels, val_data, val_labels

    @classmethod
    def list_to_data(cls, data_list):
        train_data, train_labels, val_data, val_labels = data_list
        data = cls(train_data, train_labels, val_data, val_labels)
        return data

class Fine_Tune_Model(BASE_MODEL):
    def __init__(self, train_data, train_labels, val_data, val_labels):
        super(Fine_Tune_Model, self).__init__(train_data, train_labels, val_data, val_labels)
        self.fine_tune_at = fine_tune_at

fine_tune_model = Fine_Tune_Model.list_to_data(data_lsit)

我没有正确继承超类中的属性。
