XGBoost - H2O 由于非法内存访问而崩溃

问题描述 投票：0回答：1

使用 XGBoost 进行网格搜索时，H2O 进程崩溃：

terminate called after throwing an instance of 'thrust::system::system_error'
  what():  /tmp/xgboost/plugin/updater_gpu/src/device_helpers.cuh(387): 
an illegal memory access was encountered

给出以下信息后：

xgboost 不支持

col_sample_rate_per_level
，仅支持 GBM 和随机森林： http://docs.h2o.ai/h2o/latest-stable/h2o-docs/data-science/algo-params/col_sample_rate_change_per_level.html

以下是 xgboost 网格可以使用的列表：http://docs.h2o.ai/h2o/latest-stable/h2o-docs/grid-search.html#xgboost-hyperparameters

（当然，它应该告诉你这一点，而不是崩溃，所以绝对是一个错误！）
