In Spark 2.3, When Poisson Model(with labelCol having few counts as 0's) is fit, the Deviance calculations are broken as result of log(0). I think this is the same case as in spark 2.2. But the new toString method in Spark 2.3's GeneralizedLinearRegressionTrainingSummary class is throwing error at line 1551 with NumberFormatException. Due to this exception, we are not able to get the summary object from Model fit.
Can the toString method be fixed including Deviance calculations for example taking log(1) when ever the count is 0 instead of having log(0) ?
