Question

我正在尝试为python（版本2.7.13）运行h2o，并在尝试使用h2o.init()（或h2o.h2o.init()）时收到此错误。

Checking whether there is an H2O instance running at http://localhost:54321. connected.

ImportError: cannot import name flow

我在jupyter笔记本中这样做，但是当我运行

时出现同样的错误

>>import h2o
>>h2o.init()

从控制台

。使用h2o.h2o.H2OConnection.jar_paths()显示我的h2o.jar文件在路径中，我确保h2o.jar版本和python h2o包版本相同（和最新的3.10.5.4）），所以我不确定这里可能出现什么问题。

尝试init（）h2o后运行h2o.cluster().show_status()给出输出：

H2O cluster uptime: 16 mins 56 secs
H2O cluster version:    3.10.5.4
H2O cluster version age:    23 days
H2O cluster name:   ******
H2O cluster total nodes:    2
H2O cluster free memory:    7.028 Gb
H2O cluster total cores:    16
H2O cluster allowed cores:  16
H2O cluster status: accepting new members, 1 nodes are not healthy
H2O connection url: http://localhost:54321
H2O connection proxy:   None
H2O internal security:  False
Python version: 2.7.13 final

这让我觉得init（）起作用（至少部分），但是这个错误让我想知道什么问题会潜入困境。

有关这意味着什么以及如何解决问题的帮助将不胜感激。

谢谢：）
