add_widget 函数上的 Python/Kivy 崩溃 [关闭]

Question

公平的警告，我是 Python 和 Kivy 的新手，所以我可能做的事情很明显是错误的。我正在尝试使用 Python/Kivy 动态创建网格。错误发生在这一行：

for c in range(rows):
    for d in range(cols):
        self.myBoard.add_widget(BoardSquare(x=c+1,y=d+1)) #Error occurs this line

我最初收到与 _disabled_count 相关的错误。在此guidance 之后，我将_disabled_count 设置为零。现在它运行了，但随后在本机 Kivy add_widget 函数中崩溃。它似乎停在这里：

if index == 0 or len(self.children) == 0:
   self.children.insert(0, widget)
   canvas.add(widget.canvas)

在这里，canvas.add 操作上的代码失败。应用程序整体崩溃，Python 解释器不会生成错误字符串。唯一打印的项目是：

Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)

根据其他研究，我了解到这表明存在某种分段违规，但我不知道如何解决这个问题。非常感谢您提供的任何帮助。

我正在运行 Python 3.7/Kivy 1.11/Max OSX

如上面的 cmets 所示，我在 Super 参数调用中使用了错误的参数。

我将所有调用更改为：super().__init__(**kwargs)
