Unable to find any valuable Window provider

[Caleb Ho]

I currently have Kivy 1.9.1 installed in an Anaconda virtual environment on Ubuntu 16.04. Whenever I try to run my app

python main.py

it outputs the following:

[INFO   ] [Logger      ] Record log in /home/caleb/.kivy/logs/kivy_16-07-20_22.txt

But when I call python with the -i flag it runs fine. Any ideas?

Thanks,
