AttributeError: 'CatBoostClassifier' object has no attribute 'grid_search'

Выводит ошибку AttributeError: 'CatBoostClassifier' object has no attribute 'grid_search',
хотя в документации catboost есть информация о grid_search
https://catboost.ai/docs/concepts/python-reference_catboostclassifier_grid_search.html

python
from catboost import CatBoostClassifier as clf
X = df_features.iloc[:, 3:].fillna(0)
y = df_features['fire_type']
cb_clf = clf(iterations = 1000,
                      depth = 5,
                      loss_function = 'MultiClass',
                      #learning_rate = 0.15
                      )
grid = {'learning_rate':[i/100 for i in range(1,100)],
       'l2_leaf_reg': [1, 3, 5, 7, 9]}

Текущая версия CatBoost на сегодня - 0.18.1.

Похоже в версии CatBoost 0.12.2 метод grid_search не реализован.

Попробуйте обновить версию CatBoost.
