Kivy: "Unable to find any valuable Window provider" [SOLVED]

Have you tried running it from the system terminal (outside of PyCharm) using the same interpreter?
Does the same problem appear?

I seem to have more than one Python3 version on my Ubuntu machine.

So when I write "python3 geo-esp.py" in Terminal, I get the same error, but there are a few differences in the message:

Here are the specifics from PyCharm:

[INFO ] [Python ] v3.6.7 (default, Oct 22 2018, 11:32:17)
[GCC 8.2.0]
[INFO ] [Python ] Interpreter at "/mnt/4AF15A0435E762B4/DataDoc/OneDrive/PycharmProjects/2d-graphics/venv/bin/python"

And here are the specifics from Terminal:

[INFO ] [Python ] v3.6.8 (default, Oct 7 2019, 12:59:55)
[GCC 8.3.0]
[INFO ] [Python ] Interpreter at "/usr/bin/python3"

I must admit I am not sure why there are these differences?

Any help will be very appreciated. Thank you.

There is a difference because your terminal uses another interpreter.

You need to run it with the same one /mnt/4AF15A0435E762B4/DataDoc/OneDrive/PycharmProjects/2d-graphics/venv/bin/python /mnt/4AF15A0435E762B4/DataDoc/OneDrive/PycharmProjects/2d-graphics/geo-esp-ny/geo-esp.py

Well - that command in Terminal gives this:

So you got the same error. It means that the issue is not related to PyCharm.

Try searching for similar problems. For example https://github.com/kivy/kivy/issues/5859 and https://stackoverflow.com/questions/40697876/unable-to-get-a-window-abort

Thank you for your reply!

I have been looking at the solutions you refer to plus several other related discussions. But the concrete information there is all about MS-Windows, and I use Ubuntu, so it doesn't actually help.

Specifically there are references to where python(3) is installed on Windows (7 or 10). I have tried "translating" the OS specific information from Windows to my Ubuntu 18.04.3 LTS. I tried inserting '/usr/bin/python3', but that didn't solve the problem.

So I really don't know what to do. (Except maybe trying to ask the same question somewhere else.)

Well... Further searching, specifically in askubuntu.com, got me to this solution: 

https://askubuntu.com/questions/615108/issues-finding-the-location-of-package-libsdl2-image-2-0-0 .

In short: Run this command in Terminal:

sudo apt-get install libsdl2-image-dev

That solved it. Strangely enough, since Sergey's suggestions (etc.) did not have anything to do with that command!
