我在R（Windows计算机）中使用了h2o软件包，最近更新该软件包后无法通过h2o.init对其进行初始化。
下面将显示错误消息。我想问题的原因是h2o xgboost不支持Windows（http://docs.h2o.ai/h2o/latest-stable/h2o-docs/data-science/xgboost.html）。我的猜测正确吗？如果是这样，我如何要求h2o软件包在初始化时排除xgboost以避免错误？
非常感谢。

您可以看到该问题不应与XGBoost有关。此外，在Windows上，预期的行为是XGBoost被自动禁用，您无需采取任何措施。
要解决您的问题，请尝试使用port =中的h2o.init()参数指定其他端口，以查看是否可以使h2o.init()为您工作。
原始回复
我将保留先前的答案，以防其他人遇到禁用xgboost的问题：
您可以通过将-Dsys.ai.h2o.ext.core.toggle.XGBoost设置为False来禁用xgboost
请参阅文档以获取更多详细信息：http://docs.h2o.ai/h2o/latest-stable/h2o-docs/data-science/xgboost.html#disabling-xgboost
