sklearn.exceptions.NotFittedError: This SGDClassifier instance is not fitted yet

Hello

This is the code i'm trying to run:

    X_train, y_train = prepare_data_for_ml(X_train, y_train)
    y_train, y_test = prepare_data_for_ml(X_test, y_test)

    clf = HungaBungaClassifier()
    clf.fit(X_train, y_train)

    clf.predict(X_test)

That's the error:

100%|██████████| 15/15 [00:00<00:00, 43.02it/s]

    "yet" % {'name': type(self).__name__})
sklearn.exceptions.NotFittedError: This SGDClassifier instance is not fitted yet

Am I missing something?

Thanks

Hi,
I think you overwrite the variable y_train involuntarily (second line), there should probably be X_test.
Hope that helps.
