According to what I have understood in the "Storing Trained Models" documentation, I am trying to save my trained Logistic Regression model as follow:
clf = LogisticRegression().fit(X, y)
qb.ObjectStore.Save(model_key, clf)

But I am getting this error message:
TypeError                                 Traceback (most recent call last)
<ipython-input-12-95b33bf4a492> in <module>
      3 clf = LogisticRegression().fit(X, y)
      4 joblib.dump(clf,'clf_trained.pkl')
----> 5 qb.ObjectStore.Save(model_key, clf)

TypeError: No method matches given arguments for Save

Could anyone tell me which is the right way to do this, please?

Thanks and regards,
