Hi Vinayaka, You can access the different stages in your pipeline through the stages array on our pipeline model ( http://spark.apache.org/docs/latest/api/scala/index.html#org.apache.spark.ml.PipelineModel ) and then cast it to the correct stage (if working in Scala or if in Python just access the coefficients at this point). What programming language are you working in?
