Hi! I would like to save the obtained model with the code model.write.overwrite().save("myisolatedforestmodel") but I bumped into the error: scala.NotImplementedError: The default jsonEncode only supports string, vector and matrix. org.apache.spark.ml.param.Param must override jsonEncode for java.lang.Double. Can you please check what is the issue?

Thanks for reporting it. It was caused by an incorrect param type in last updates. I have just fixed it. Pull the latest codes and try again.
