I'd like to contribute to Orange. To get used to the code, I tried to run the source code directly under Windows 10, so far without success. I have numpy and scipy installed, and the source code for orange3 from GitHub. If I run "python -m Orange.canvas" in the orange3 directory, I get the following error stack:

Traceback (most recent call last):

Does anyone has experience with trying to run Orange directly from the source code? Any help is appreciated!
