有没有人有任何想法为什么这段代码给出了分段错误？Kivy代码分段错误
从nodeapp.py
from kivy.app import App
from kivy.uix.widget import Widget
from kivy.uix.floatlayout import FloatLayout
class Node(Widget):
def __init__(self):
pass
inputs = 1
function = "add"
class NodeApp(App):
def build(self):
fl = FloatLayout()
nod = Node()
fl.add_widget(nod)
return fl
if __name__ == '__main__':
NodeApp().run()
从node.kv
<Node>:
size: 0.5,0.5
canvas:
Rectangle:
pos: 1,1

谷歌搜索的问题，使我更新我的显卡司机（现在在1 4.7 RC，最新版本）和使用ensure_window（），两者都没有解决问题。
注释掉__init__解决分段错误，但使我不能用__init__任何东西
