Although my issue seems local to my system (and therefore, maybe not a kivy3 bug), Kivy3's 'setup.py' should (imho ;) ) be made to catch such issue, so the eager and frustrated beginner can run the included examples, or be told why not - hence a submitted issue on Kivy3's 'setup.py'.
I first had an issue with: 'FileNotFoundError: [Errno 2] No such file or directory: '/usr/lib/python3.6/site-packages/kivy3/default.glsl', so I had to try a copy from another source & a renamed simple.glsl. It didn't seem to make a difference which one, but it brought me a step closer, and i'm not really sure what i'm doing.
The following problem are consistent for all 3 exampleX.py files, over several pip/pacman re-install of Python 3.6, kivy 1.9.1 + 1.10, and this branch of kivy3. Python & kivy itself works.
example1.py: (short code to reproduce issue)
import kivy3
from kivy.app import App
from kivy3.loaders import OBJLoader
from kivy.uix.floatlayout import FloatLayout
class MainApp(App):
def build(self):
root = FloatLayout()
loader = OBJLoader()
obj = loader.load("./testnurbs.obj") # obj_path)
return root
if name == 'main':
MainApp().run()
Traceback (most recent call last):

tc = Vector2(t[0], 1. - t[1])
TypeError: 'map' object is not subscriptable
If it's an obvious dependency flaw, then perhaps a quick check for it in setup.py could trigger a warning, or something, and if it's a rare dependency flaw, then what's missing ? Thanks..
PS. looking forward to work with this library of fun-ness..

Hi.
