In our subsequent sections, you will see the instructions for installation of H2O based on the options available. You are likely to use one of the options.
在我们的后续章节中,您将根据可用选项查看安装H2O的说明。 您可能会使用其中一个选项。
在Python中安装 (Install in Python)
To run H2O with Python, the installation requires several dependencies. So let us start installing the minimum set of dependencies to run H2O.
要使用Python运行H2O,安装需要几个依赖项。 因此,让我们开始安装最小的依赖关系集以运行H2O。
安装依赖项 (Installing Dependencies)
To install a dependency, execute the following pip command −
要安装依赖项,请执行以下pip命令-
$ pip install requests
Open your console window and type the above command to install the requests package. The following screenshot shows the execution of the above command on our Mac machine −
打开控制台窗口,然后键入以上命令以安装请求包。 以下屏幕截图显示了在Mac机器上执行上述命令的过程-

After installing requests, you need to install three more packages as shown below −
安装请求后,您需要再安装三个软件包,如下所示:
$ pip install tabulate
$ pip install "colorama >= 0.3.8"
$ pip install future
The most updated list of dependencies is available on H2O GitHub page. At the time of this writing, the following dependencies are listed on the page.
H2O GitHub页面上提供了最新的依赖关系列表。 在撰写本文时,页面上列出了以下依赖项。
python 2. H2O — Installation
pip >= 9.0.1
setuptools
colorama >= 0.3.7
future >= 0.15.2
删除旧版本 (Removing Older Versions)
After installing the above dependencies, you need to remove any existing H2O installation. To do so, run the following command −
安装以上依赖项后,您需要删除所有现有的H2O安装。 为此,请运行以下命令-
$ pip uninstall h2o
安装最新版本 (Installing the Latest Version)
Now, let us install the latest version of H2O using the following command −
现在,让我们使用以下命令安装最新版本的H2O-
$ pip install -f http://h2o-release.s3.amazonaws.com/h2o/latest_stable_Py.html h2o
After successful installation, you should see the following message display on the screen −
成功安装后,您应该在屏幕上看到以下消息显示-
Installing collected packages: h2o
Successfully installed h2o-3.26.0.1
测试安装 (Testing the Installation)
To test the installation, we will run one of the sample applications provided in the H2O installation. First start the Python prompt by typing the following command −
为了测试安装,我们将运行H2O安装中提供的示例应用程序之一。 首先通过键入以下命令来启动Python提示符-
$ Python3
Once the Python interpreter starts, type the following Python statement on the Python command prompt −
Python解释器启动后,在Python命令提示符下键入以下Python语句-
>>>import h2o
The above command imports the H2O package in your program. Next, initialize the H2O system
