[oort77]

Describe the bug

Jupyter notebook returns an error: "NameError: name 'Integer' is not defined"

To Reproduce

atom.run(
    models=["GBM", "XGB", "CATB", "LGB"],
    metric=["roc_auc_ovr", "f1_weighted"],
    n_calls=25,
    n_initial_points=10,
    bo_params={"dimensions":[Integer(100, 1000, name="n_estimators"),  
                            Integer(3, 6, name="max_depth"),   
                            Real(0.01, 1, "log-uniform", name="learning_rate")],  
                            "base_estimator":"RF", "max_time":10000},  
    n_bootstrap=5,
)```

You need to import Integer and Real from scikit-optimize. Type this at the top of the notebook:

from skopt.space.space import Real, Integer
