[2017-01-11 18:21:02,284] ERROR {org.wso2.carbon.ml.core.impl.MLModelHandler} - Failed to build the model [id] 9 org.wso2.carbon.ml.core.exceptions.MLModelBuilderException: An error occurred while building logistic regression model: For input string: ",06" at org.wso2.carbon.ml.core.spark.algorithms.SupervisedSparkModelBuilder.buildLogisticRegressionModel(SupervisedSparkModelBuilder.java:322)

resolved - the problem is caused by italian setting system operation. That use "comma separated" character for decimal and not "dot" character. I have resolved changed the settings.
