hi mullerhai, We already use org.apache.spark.ml.param.shared.{HasFeaturesCol, HasPredictionCol} in Analytics Zoo. spark.ml.adapter.HasFeaturesCol actually extends that in Analytics Zoo https://github.com/intel-analytics/analytics-zoo/blob/master/zoo/src/main/scala/com/intel/analytics/zoo/pipeline/nnframes/SharedParamsAdapter.scala Could you please share your code and detailed error messages?
