kivy 应用程序中的错误：object.__init__() 只采用一个参数（要初始化的实例）

Question

我正在尝试制作一个表单应用程序，但我不明白该错误。不幸的是，我在很多方面都未能解决它：

TypeError: object.__init__() takes exactly one argument (the instance to initialize)

代码如下：

from kivy.uix.gridlayout import GridLayout
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.label import Label
from kivy.uix.image import Image
from kivy.graphics import Color, Rectangle
import kivy.utils


class UsersBanner(GridLayout):

    def __init__(self, **kwargs):
        self.rows = 1
        super(UsersBanner, self).__init__(**kwargs)
        with self.canvas.before:
            Color(rgb=(kivy.utils.get_color_from_hex("#67697C")))
            self.rect = Rectangle(size=self.size, pos=self.pos)
        self.bind(pos=self.update_rect, size=self.update_rect)

        # need left float layout
        left = FloatLayout()
        user_label = Label(text=str(kwargs['user_name']), size_hint=(1, .3), pos_hint={"top": .225, "right": 1})
        left.add_widget(user_label)
        # need middle float layout
        middle = FloatLayout()
        nationality_label = Label(text=str(kwargs['nationality']), size_hint=(1, .3), pos_hint={"top": .225, "right": .9})
        middle.add_widget(nationality_label)
        # need right float layout
        right = FloatLayout()
        user_image = Image(source="icons/users/" + kwargs['user_image'], size_hint=(1, .3),
                           pos_hint={"top": .225, "right": .7})
        right.add_widget(user_image)

        self.add_widget(left)
        self.add_widget(middle)
        self.add_widget(right)

    def update_rect(self, *args):
        self.rect.pos = self.pos
        self.rect.size = self.size

错误：

如果你只用这两个参数创建一个对象

uu = UsersBanner(user_name=user['user_name'],  nationality=user['nationality'])

你能在 USerbanner init 中试试这个吗

def __init__(self,user_name,nationality, **kwargs):   # intead of def __init__(self, **kwargs):

如果有的话，你可以添加其他变量
