    from sklearn.datasets import load_breast_cancer
    from sklearn.model_selection import train_test_split

    data = load_breast_cancer()
    X = data.data
    y= data.target

    X_train, X_test, y_train, y_test = train_test_split(X, y,test_size=.5,random_state =123)

    clf = LazyClassifier(verbose=0,ignore_warnings=True, custom_metric=None)
    models,predictions = clf.fit(X_train, X_test, y_train, y_test)
