This is absolutely this problem.
Good to hear it will be fix in 2.3 release

Nicolas, are you referring to printing the model params in that example
with "print(model1.extractParamMap())"? There was a problem with pyspark
models not having params after being fit, which causes this example to show
nothing for model paramMaps. This was fixed in

Hey
I am also interested in how to get those parameters.
For example, the demo code
spark-2.2.1-bin-hadoop2.7/examples/src/main/python/ml/estimator_transformer_param_example.py
return empty parameters when printing "lr.extractParamMap()"
That's weird
Thanks

Hi Michelle,
Your original usage of ParamGridBuilder was not quite right, `addGrid`
expects (some parameter, array of values for that parameter). If you want
to do a grid search with different regularization values, you would do the
following:
val paramMaps = new ParamGridBuilder().addGrid(logis
I tried to use One vs Rest in spark ml with pipeline and crossValidator for
multimultinomial in logistic regression.
It came out with empty coefficients. I figured out it was the setting of
ParamGridBuilder. Can anyone help me understand how does the parameter
setting affect the crossValidator pro
