Check_arrays() Limiting Array Dimensions In Scikit-learn?

I would like to use the sklearn.learning_curves.py available in scikit-learn X0.15. After I cloned this version, several functions no longer work because check_arrays() is limiting

Solution 1:

Because scikit-learn uses a 2-d convention (n_samples × n_features) for all feature data. If any function or method lets a higher-d array through, that's usually just oversight and you can't really rely on it.
