Answer 2

Angle backend for py3.5+

pip install kivy.deps.angle 
set KIVY_GL_BACKEND=angle_sdl2

It works perfectly on windows 10 and its solution for above problem. Multisample won't work in my case

Answer 3

I had the same problem as said above. Simply adding angle_sdl2 to the user environment variable was enough to solve the problem—it worked for me.

Answer 4

First of all, I am using Python 3.7.

I followed the below instruction first:

1. Right click on This PC then open Properties.
2. Go to Advanced system settings.
3. Click on Environment Variables.
4. Click on New in User variables for ---.
5. Put KIVY_GL_BACKEND in Variable name.
6. Put angle_sdl2 in Variable value .
7. Restart Python

Then I run the following in my IDE on Windows 10 and it worked for me

from kivy import Config
Config.set('graphics', 'multisamples', '0')
import os
os.environ['KIVY_GL_BACKEND'] = 'angle_sdl2'
import kivy
from kivy.app import App
from kivy.uix.label import Label

class MyApp(App):
    def build(self):
        return Label(text="Tech With Me")

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

Answer 5

I was packaging my application with pyinstaller and none of the above worked on my windows 10 machine to run a Python App.

After searching further, This is what that solved my problem.

Navigate to dist folder where your application (.exe) is. Delete the .manifest file, named after your App name i.e (myappname.exe.manifest).

The Error should be gone now, As old as from the 90's machines, OPenGL will be found!

Answer 6

Change multisamples key value in config file (%HOMEPATH%\.kivy\config.ini for me) from multisamples = 2 to multisamples = 0.
