inconsistent use of tabs and spaces in indentation

That is a little wired. Are you using the latest pull request?
It works fine on my computer and I can't see anything wrong with tabs or spaces.
Maybe you can try add [1:] in the right place manually?

I am pretty sure that

RuntimeWarning: invalid value encountered in sign

This warning is caused by test['correct'] = (np.sign(test['pred_diff']) == np.sign(test['real_diff'])) * 1 ^ And by adding [1:] begind test[''] will solve this.
