Import numpy earlier

[rajshah4]

Hi, great notebook!
When I ran this, I needed to import numpy earlier to get pass the line - np.set_printoptions(suppress=True)

I added it under the Tools used block of code.

Thanks

Ah, good catch. Feel free to make a PR or I can fix it. I often have these imports defined in my IPython config and forget.
