GridSearchCV只保存一个估计值

Question

如何只保存一个GridSearchCV估计量？当我使用作业库转储函数，它生成了数百个文件为“最佳估计器”。在

model=cv.best_estimator_
joblib.dump(model, 'model.pkl')

Answer 1

Note: joblib.dump returns a list of filenames. Each individual numpy array contained in the clf object is serialized as a separate file on the filesystem. All files are required in the same folder when reloading the model with joblib.load.
