Run h2o.ai as a service (background)

Question

How to run H2O.ai python in background?

I tried putting

import h2o
h2o.init()
input() # to stop closing the python program

in a python script and run with nohup python3 script.py & . But the script exits if I enter the return key. Is there a way to avoid this behavior and run h2o.ai in background?

Answer 1

Your Python session is ending, and thus your H2O cluster may be stopping.

You can start H2O 3 from Command Line , for example:

java -jar h2o.jar

^you will need to be in the directory of your H2O 3 folder (like here ).

Alternatively, you can add sleep to your script:

import time
time.sleep(10)

^this will leave the program running for 10 seconds. If you want to extend it, just add more seconds to the max time you want the program to run.
