FIX predict_proba status on SGD and SVC when disabled
...
Using a property trick suggested by @mblondel. The following now
works:
>>> clf = SVC(probability=False)
>>> hasattr(clf, "predict_proba")
False
This simplifies the smoke tests.
Added a note to SVC stating that this should be done in new code.
