If I use predict_proba with svm.SVC I get:
probas = model_svm.predict_proba(data_test)
File "C:\Python26\lib\site-packages\sklearn\svm\base.py", line 490, in
predict_proba "probability estimates must be enabled to use this method")
NotImplementedError: probability estimates must be enabled to use this
method
