Kivy Runtime Error Unable to find any valuable window provider

[murali the warrior]

Hi kivy Team,

Greeting for the day!

Myself Murali. I'm from India. We are looking for some cross-platform libraries to build a few applications as an initiative for upcoming projects.

I have heard about Kivy tried to use it. For the Last 24 hrs, I'm trying to run a simple kivy app. It's not running. It shows Unable to find any valuable window provider error.

I have gone throw all your issues and tried all solutions. But none of them worked for me. I don't know what's wrong. Please let me know how to solve this. Otherwise, there is no option for me to move for another framework.

It will be helpful if you give any support.

My Code 

import os

os.environ['KIVY_GL_BACKEND'] = 'sdl2'

import kivy

kivy.require('1.11.1')

from kivy.app import App

from kivy.uix.label import Label

class MyApp(App):

def build(self):

return Label(text='Hello world')

if __name__ == '__main__':

MyApp().run()

I'm using Ubuntu 20.04LTS. VS Code as codeeditor. 

Using python 3.7

This looks like an install issue.   Did you follow the directions here:

Yeah. I installed perfectly by those description. After that I have uninstalled and reinstalled with conda also. Still the issue is occurring

Hi Murli,

Please setup new virtual environment in case of installation issue.

Hi Arumugam,

I have installed pycharm and created a new environment. Installed kivy package.

Tried to install kivy-deps.angle, kivy-deps.glew, kivy-deps.gstreamer. I had following error. 

ERROR: Could not find a version that satisfies the requirement kivy-deps.angle (from versions: none)

ERROR: No matching distribution found for kivy-deps.angle

ERROR: Could not find a version that satisfies the requirement kivy-deps.glew (from versions: none)

ERROR: No matching distribution found for kivy-deps.glew

ERROR: Could not find a version that satisfies the requirement kivy-deps.gstreamer (from versions: none)

Hi Murli,

May I know your Python version?

Python 3.6 is best suitable for Kivy.

Arumugam Maharaja M.

I'm using Python 3.7.7. I thought it's a supported version.

3.7 is fine.  This is an install issue, but what?

I see Kivy    2.0.0rc3   is installed. This didn't happen by following the install instructions ;)

Uninstall this version then follow the instructions, you may want this version for some reason but since nobody has any idea what the issue is we need to remove any variable we can.

Next, don't use the wheel, it clearly says Linux wheels are experimental.

It appears you may be using conda, if this is the use the conda install instructions.

Forget running from your editor (if you are doing this), run everything from the command line.

This may not be what you want but there is a strange issue here so start simple.
