HI
os: win7
Rstudio: 1.0.143
R : 3.4
issue:
all h2o learner fails in prediction task: seems this is class levels names conflit:

"Error in checkPredictLearnerOutput(.learner, .model, p) :
predictLearner for classif.h2o.gbm has returned not the class levels as column names: p0, p1"

checking current names in learner , those lacks 'p' prefix; in fact they are '0', '1' and not 'p0, p1' as needed
