当我尝试使用以下命令导出随机森林图时:
tree.export_graphviz(rnd_clf, out_file = None, feature_names = X_test[::1])

我收到以下错误:
NotFittedError: This RandomForestClassifier instance is not fitted yet.
Call 'fit' with appropriate arguments before using this method.

我不明白为什么它一直告诉我这个,即使我已经使用以下方法拟合随机森林分类器:
rnd_clf = RandomForestClassifier(
n_estimators=120,
criterion='gini',
max_features= None,
max_depth = 14 )
rnd_clf.fit(X_train, y_train)

它完美无缺.
