我是火花的新手，试图在Scala中生成决策树模型并在Java中使用该模型进行预测。如何在Java中加载该模型？

Question

i have saved the model generated in scala to disc.

val model = DecisionTree.trainClassifier(trainingData, numClasses, categoricalFeaturesInfo, impurity, maxDepth, maxBins) model.save(sc, "C:\\Model")

Answer 1

对Java使用相同的导入以加载模型：

DecisionTreeModel model = DecisionTreeModel.load(sc, "C:\\Model");
