 ## Step 3: Handling the missing data
 ```python
-from sklearn.preprocessing import Imputer
-imputer = Imputer(missing_values = "NaN", strategy = "mean", axis = 0)
+from sklearn.impute import SimpleImputer
+imputer = SimpleImputer(missing_values = 0, strategy = "mean")
 imputer = imputer.fit(X[ : , 1:3])
 X[ : , 1:3] = imputer.transform(X[ : , 1:3])
