col_sample_rate_per_level is not supported for xgboost, only GBM and random forest:http://docs.h2o.ai/h2o/latest-stable/h2o-docs/data-science/algo-params/col_sample_rate_change_per_level.html

以下是您可以与xgboost网格一起使用的列表: http://docs.h2o.ai/h2o/latest-stable/h2o-docs/grid-search.html#xgboost-hyperparameters
