Programming error

In section 5 unit 13 testing and predicting. I do not know what is the error in my code:



ss1 = StandardScaler()

cls.fit(ss1.fit_transform(X.iloc[:split]), y.iloc[:split])

y_predict = cls.predict(ss1.transform(X.iloc[:split]))





the error message says:

Have you called cls.fit method?

 

Hello Hugo,



Please reconfirm the range of values of the dataframe X you're passing into cls.predict with the solution code.
