H2O AutoML returns "H2OFrame is empty" 的时候怎么办？

Question

在使用 H2o AutoML 在 SageMaker 实例上训练作业时，在运行代码后出现消息 "This H2OFrame is empty"，我应该如何解决该问题？

/opt/ml/input/config/hyperparameters.json

我想知道这是否是因为 max_runtime_secs 造成的问题，我的数据大约有 500 行和 250000 列。

Answer 1

做了一些测试我意识到问题是因为 max_runtime，我相信我没有让模型进行足够的训练。

Answer 2

感谢@Marcel Mendes Reis 在评论中跟进您的解决方案。我会在这里重新发布以供其他人轻松找到：

我意识到问题是由于 max_runtime。当我用更多时间训练模型时，我没有遇到问题。
