Robot-Marbles-Part-6.ipynb gives an unexpected error when run on windows.

To recreate the bug:

1. Pull code from default branch.
2. Run all steps in the robot-marbles-part-6 notebook.

Fails on step 17 with NameError: name 'rand' is not defined

Expected: results of both configurations should be appended to the “results” variable.

Thanks, @ResourceHog . I guess that makes sense. For a while now in our internal projects we’ve been separating the model definition from the analysis notebook for better version control (same project structure used in the prey-predator example), so that’s another reason why we didn’t catch this.

We need to think about how to handle the tutorials given this. IMO, the ideal experience for a newcomer would not require parsing multiple files, as I believe introducing concepts and corresponding code snippets throughout the notebook makes the tutorial more readable and accessible. I’ll think about it and I’m happy to hear different points of view and suggestions others might have.
