Please convert this notebook to Python 3

Please convert this notebook to Python 3. I get errors in print statements and plt.errorbar.

It may be helpful to use the print function from the future module:
from __future__ import print_function

I was using version 2.0.2 of matplotlib, perhaps updating matplotlib can solve the plt.errorbar problem:
sudo pip3 install --upgrade matplotlib

Conversion to Python 3 was very easy...

You've just to add parenthesis to print statement.
print("Accuracy: %.2f (+/- %.2f) [%s]" %(scores.mean(), scores.std(), label))

And enlist some maps for the new errorbar API
num_est = list(map(int, np.linspace(1,100,20)))

The only non-critical problem was mysterious warnings that was not able to figure exactly the origin although I've updated, mlxtend, matplotlib and numpy... Anyway, I would not spend a lot of time on more cosmetic issue.

« MaskedArrayFutureWarning: In the future the default for ma.maximum.reduce will be axis=0, not the current None, to match np.maximum.reduce. Explicitly pass 0 or None to silence this warning.
return self.reduce(a) »

Thank you Vadim!

Thanks @ClaudeCoulombe for the detailed solution!
