Subject Random Forest gererate model failed (DecisionTree.scala:642), which has no missing parents
Date Fri, 15 Jul 2016 12:14:17 GMT
Hi,

I am trying to create the Random Forest model, my source_code as follows:
val rf_model  = RandomForest.trainClassifier(trainData, 7, Map[Int,Int](),
20, "auto", "entropy", 30, 300)


I got following error:
