In the last chapter, you learned to create H2O based ML models using command line interface. H2O Flow fulfils the same purpose, but with a web-based interface.
In the following chapter, I will show you how to start H2O Flow and to run a sample application.
The H2O installation that you downloaded earlier contains the h2o.jar file. To begin H2O Flow, first run this jar from the command prompt −
$ java -jar h2o.jar
When the jar runs successfully, you will get the following message on the console −
Open H2O Flow in your web browser: http://192.168.1.10:54321
Now, open the browser of your choice and type the above URL. You would see the H2O web-based desktop as appeared here −
This is basically a notebook similar to Colab or Jupyter. I will show you how to load and run a sample application in this notebook while explaining the various features in Flow. Click on the view example Flows link on the above screen to see the list of provided examples.
I will describe the Airlines delay Flow example from the sample.
