In your code, 'document' is just a string, not a feature vector. You should use the same Vectorizer that you used to train the classifier to begin with. Trained classifier objects are generally not compatible across versions. You should retrain the classifier using the new version (and who knows,

Hi Ark Thanks for reporting the issue. Could you please provide a minimum code sample to reproduce and open an issue on github. That would be great. Which version of sklearn are you using? Also, are you aware that you don't need the OneVsRestClassifier for multi-class support in SGDClassifier? S

Hello, I see an issue with predict in case of predicting a text document. [I load an already trained classifier (OneVsRest(SGDClassifier(loss=log))) using joblib.load]. Thanks. In [1]: import sklearn In [2]: from sklearn.externals import joblib In [4]: clf = joblib.load("classifier.joblib
