GLM param, class_sampling_factors ''[0.2]" gets exception msg in model_builders: [F cannot be cast to [Ljava.lang.Object;

[exalate-issue-sync[bot]]

that's the exception. Not really informative enough if I'm doing something wrong Supposedly class_sampling_factors takes '[float]' so I gave it '[0.2]' dataset is covtype20k.data. Maybe I'm supposed to have a list of values equal to the # of classes? or ??

The test munges covtype20k.data so col 54 is 0/1 (int) 0/1 int is legal for GLM binomial...doesn't have to be enum. If I remove the class_sampling_factors from the parameter dict for the test, it runs.

to run cd h2o-dev/py2/testdir_single_jvm python test_GLM_error1.py

add -uc if you want to connect to existing h2o.jar localhost:54321

here's what the test did ..you can see the GLM params

Tomas Nykodym commented: Class sampling factors is not supported at all for glm. We should fix the api to not to show irrelevant inherited params.
