Python Kivy:TypeError:object.\uuuu init\uuuuu（）只接受一个参数（要初始化的实例）

我一直在尝试修复这个错误，当我尝试向继承Gridlayout的类添加一个小部件时，我不知道继承小部件的类是问题所在还是Gridlayout问题所在，我一直在尝试做很多没有结果的事情，所以我想问一下这是否有解决方案

第一个类是继承小部件的类

class MyPaintElement(Widget):
def __init__(self, **kwargs):
    super(MyPaintElement, self).__init__(**kwargs)
    self.active = False

def on_touch_down(self, touch):
    # Check if touch event is inside widget
    if self.collide_point(touch.x, touch.y):
        self._draw_rectange()

def on_touch_move(self, touch):
    # Check if touch event is inside widget
    if self.collide_point(touch.x, touch.y):
        # If so, draw rectangle
        self._draw_rectange()

def _draw_rectange(self):
    self.canvas.clear()
    with self.canvas:
        # lets draw a semi-transparent red square
        Color(1, 1, 1, 1, mode='rgba')
        Rectangle(pos=self.pos, size=(self.width*0.9, self.height*0.9))
    self.active = True

def clear(self, color):
    self.canvas.clear()
    with self.canvas:
        if color == "black":
            # lets draw a semi-transparent red square
            Color(0, 0.65, 0.65, 1, mode='rgba')
        else:
            Color(0, 0.2, 0.2, 1, mode='rgba')
        Rectangle(pos=self.pos, size=(self.width*0.9, self.height*0.9))
    self.active = False

def mark(self):
    self._draw_rectange()

第二个类是我在“add_widget”部分中调用这个实例的地方，它继承了GridLayout

class MyPaintWidget(GridLayout):

CODING_SIZE = 4

def __init__(self, size, **kwargs):
    super(MyPaintWidget, self).__init__(**kwargs)
    self.cols = size
    for index in range(self.cols * self.cols):
        self.add_widget(MyPaintElement())

def clear(self):
    index = 0
    #with self.canvas.before:
    #    Color(0, .1, .3, 1)  # green; colors range from 0-1 instead of 0-255
    #    self.rect = Rectangle(size=self.size,
    #                         pos=self.pos)

    for child in self.children:
        if index % 2:
            child.clear("dark-turquoise")
        else:
            child.clear("black")
        index += 1

def get_pattern(self):
    # Initial pattern is an empty list of integers
    pattern = []
    # Integer representation or first row of pattern (bottom)
    val = 0
    # Counter to obtain integer value from binary row
    count = 1
    # For each MyPaintElement instance, verify if active and
    # add integer value to val depending on its position (count)
    for child in self.children:
        if child.active:
            val += count
        count *= 2
        # If row over, append to pattern array and
        # start encoding new one
        if count == pow(2, MyPaintWidget.CODING_SIZE):
            pattern.append(val)
            val = 0
            count = 1
    return pattern

def draw_pattern(self, pattern):
    """ Draw given pattern in painter"""
    for index in range(len(pattern)):
        # Get children in groups of four (As codification was made by groups of four)
        child_offset = index*MyPaintWidget.CODING_SIZE
        child_set = self.children[child_offset:child_offset+MyPaintWidget.CODING_SIZE]
        # Convert current number of pattern into binary
        format_str = "{0:0"+str(MyPaintWidget.CODING_SIZE)+"b}"
        bin_pattern_element = format_str.format(pattern[index])
        # Traverse binary, mark or clear corresponding child
        for j in range(len(bin_pattern_element)):
            if bin_pattern_element[MyPaintWidget.CODING_SIZE-1-j] == "1":
                child_set[j].mark()
            else:
                if j % 2:
                    child_set[j].clear("dark-turquoise")
                else:
                    child_set[j].clear("black")

最后，它给我的错误是

所以，我想知道为什么会发生这种情况，我真的很感激任何建议或建议

我认为网格布局的列没有初始化

super(MyPaintWidget, self).__init__(**kwargs)

需要修改为

super(MyPaintWidget, self).__init__(size)

我一直在寻找相同的解决方案，但我尝试以不同的方式“调用”该应用程序，结果成功了。试试这个：

class MyApp(App):

    def build(self):
        return Label(text='Hello world')

#this is what i call "calling":
if __name__ == '__main__':
    MyApp().run()

---

你好我尝试了这个，但它抛出了一个错误，

super（MyPaintWidget，self）。\uuuu init\uuuu（size）TypeError:\uuuuu init\uuuuu（）接受1个位置参数，但给出了2个
