 This example shows how you can port a model from the command line. First of all you have to store the model to the [pickle format](http://scikit-learn.org/stable/modules/model_persistence.html#persistence-example):
 
 ```python
-from sklearn.datasets import load_iris
-from sklearn.tree import tree
-from sklearn.externals import joblib
-
-# Load data and train the classifier:
-iris_data = load_iris()
-X, y = iris_data.data, iris_data.target
-clf = tree.DecisionTreeClassifier()
-clf.fit(X, y)
+# ...
 
 # Extract estimator:
 joblib.dump(clf, 'model.pkl')
