Python / Kivy App running only once

Question

I\'m running a very simple python (3.5) script using Spyder IDE from Anaconda platform.

from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.gr         


        

Answer 1

Not that much Kivy-related problem. Spyder probably keeps old stuff in memory? Try in a simple interpreter type your code line by line. Then close the app and try again typing TestApp().run() - the same three lines.

This way you'll see that if the old stuff (variables, classes, whatever is still accessible) is present, Kivy won't allow you to launch the app (still a mistery to me, maybe because of window-related code?)

If there is something in Spyder to flush old stuff from memory, then set it after each Kivy exit and you should be good to go.
