TypeError:\uuuu init\uuuuuuuuuu（）在Kivy中获得了意外的关键字参数“\uuuu no\u builder”

Question

所以，当我试图为github运行一个示例代码，创建麦克风数据的实时绘图时，我遇到了这个错误。错误为TypeError:init（）获取了意外的关键字参数“\uu no\u builder” 我已尝试将 def __init__(self,): super(Logic, self).__init__()in更改为 def __init__(self, **kwargs): super(Logic, self).__init__(**kwargs)。这是堆栈溢出中的某个人建议的，但不起作用。我正在这里发送完整的代码。。。 “”“使用kivy实时绘制麦克风音量 “”“
