如何在kivy中用图片替换标签中的文本？

from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.image import Image

class MyApp(App):
    def build(self):
        # 创建一个Label标签
        label = Label(text='Hello World!', font_size='30sp')
        
        # 创建一个Image标签
        image = Image(source='path_to_image.png')
        
        # 将Image标签替换Label标签
        label.texture = image.texture
        
        return label

if __name__ == '__main__':
    MyApp().run()
