I just installed KivyMD. When I try to run a simple code from “Getting Started” on kivymd page.

from kivymd.app import MDApp
from kivymd.uix.label import MDLabel

class MainApp(MDApp):
    def build(self):
        return MDLabel(text="Hello, World", halign="center")


MainApp().run()

But I get this error:

Traceback (most recent call last):
   File "c:kivymdMDvirtfirsproject.py", line 2, in <module>
     from kivymd.uix.label import MDLabel

          ^^^^^

Any ideas why?
