Sklearn train_score
WebbWe build a model on the training data and test it on the test data. Sklearn provides a function train_test_split to do this task. It returns two arrays of data. Here we ask for 20% of the data in the test set. train, test = train_test_split (iris, test_size=0.2, random_state=142) print (train.shape) print (test.shape) Webbsklearn决策树 DecisionTreeClassifier建立模型， 导出模型， 读取 来源：互联网 发布：手机变麦克风软件 编辑：程序博客网 时间：2024/04/15 11:25
