PyCharm does not see the Add method. How to fix?

Question

Python

I tell everything as it was.
I installed Kivy.
Run test program on command line

from kivy.app import App
from kivy.uix.button import Button


class TestApp(App):
    def build(self):
        return Button(text='Hello World')


TestApp().run()

Everything worked, hurray!!!
Then I started trying the same code in PyCharm, it doesn’t work, it gives an error of such a plan
Traceback (most recent call last):
File "D:/PythonLessons/Kivy.py", line 1, in
from kivy.app import App
ImportError: cannot import name 'App'
All day I asked Google what to do, I did not find an answer (((
Please tell me what to do ????
