Apache spark PredictionIO培训失败
我对预测一无所知。我正在使用模板 我的培训数据集计数为1184603,具有大约6500个功能。我使用的是ec2 r4.8X大型系统(240 GB RAM,32核,200 GB交换) 我试过两种训练方法Apache spark PredictionIO培训失败,apache-spark,apache-spark-mllib,predictionio,Apache Spark,Apache Spark Mllib,Predictionio,我对预测一无所知。我正在使用模板 我的培训数据集计数为1184603,具有大约6500个功能。我使用的是ec2 r4.8X大型系统(240 GB RAM,32核,200 GB交换) 我试过两种训练方法 指挥部 pio列车----驾驶员存储器120G--执行器存储器100G--conf spark.network.timeout=10000000 " 3-4小时后会出现抛出异常 Exception in thread "main" org.apache.spark.SparkException:
