H2O python split_frame 抛出异常

Question

我正在尝试拆分我的 h2o 帧，但我一直在下方收到异常，但我能够在 Flow UI 中看到拆分的帧。我试图查找文档，试图找到如何将我在 Flow UI 中看到的框架加载到我的 python shell 中，但也没有成功。

data = h2o.import_frame("train.csv")
Parse Progress: [##################################################] 100%
Imported train.csv. Parsed 878,035 rows and 5 cols

splits = data.split_frame(ratios=[0.80])

这已在最新的稳定版本中修复

python 没有轮询等待拆分帧完成，然后再进入下一步（导致未找到异常）
