OSError：安装h2o时版本不匹配？

问题描述 投票：0回答：4

我是H2o的新手。基于documentation，我为python安装了H2o

$ pip install h2o

然后：

输入：

import h2o
h2o.init()

输出：

    177           raise EnvironmentError("Version mismatch. H2O is version {0}, but the h2o-python package is version {1}. "

OSError: Version mismatch. H2O is version 3.8.2.99999, but the h2o-python package is version 3.8.2.6-1. This is a developer build, please contact your developer.

从此website，我尝试如下解决此问题：

h2o.shutdown

然后：

  Successfully uninstalled h2o-3.8.2.6-1
user@MacBook-Pro-of-User:~$

然后我尝试升级到最新版本：

user@MacBook-Pro-of-User:~$ pip3 install http://h2o-release.s3.amazonaws.com/h2o/rel-turchin/6/Python/h2o-3.8.2.6-py2.py3-none-any.whl

但是，我得到了相同的错误消息：

OSError: Version mismatch. H2O is version 3.8.2.99999, but the h2o-python package is version 3.8.2.6. This is a developer build, please contact your developer.

如何正确安装python的h2o？。

首先尝试使用最新版本的H2O：

pip3 uninstall h2o
pip3 install http://h2o-release.s3.amazonaws.com/h2o/rel-turchin/9/Python/h2o-3.8.2.9-py2.py3-none-any.whl

如果遇到相同的问题，请执行以下操作：

看来您已经在计算机上运行了H2O的开发版本（3.8.2.99999）。您将需要杀死正在运行开发版本的H2O群集。您可以通过以下方式之一进行操作：

  • 导航到H2O Flow Web GUI（如果您在本地运行，则默认为localhost：54321）。在GUI中，单击“管理”菜单项，然后单击“关闭”。
  • 杀死正在运行H2O集群的Java进程。

一旦您杀死了现有的H2O集群，然后重新安装h2o模块，然后直接从Python启动H2O集群，如下所示：

import h2o
h2o.init()

由于此刻将不会运行现有的H2O集群，因此h2o Python模块将为您启动一个（由于您是从Python启动的，因此不会对版本感到困惑）。

有时会发生的情况是，人们分别下载H2O jar文件，启动H2O集群，然后安装其他版本的R或Python软件包，这会导致不匹配错误。我认为这可能是您遇到问题的原因。通常，启动H2O群集就像import h2o; h2o.init()一样简单。

In order to use H2O, need to update the h20 jar file to python version.

如果打开h2o窗口@ http://localhost:54321，请确保在导入python或python3之前先将其关闭（Admin-> shutDown），因为它们会产生冲突。

默认情况下，H2O对于版本不匹配非常宽容。
