Quick Start with the ModelOp Center OVA

Get started with ModelOp Center quickly by importing the ModelOp Center Virtual Appliance into the Oracle VirtualBox Manager. We have made it easy by providing you with a pre-configured ModelOp Center fleet and two demos that will walk you through deploying a model with ModelOp Center:

4. Power On the ModelOp Center Machine

  1. When the boot is complete, you will be presented with a prompt to login

5. Login to the Box

When prompted, login to the box: User: ModelOp Center Password: ModelOp Center Upon first login, the “hello-world” demo will launch automatically. Follow along by pressing Enter or press ctrl+c to escape the demo.

ModelOp Center is now up and running. The ModelOp Center Dashboard is accessible from your host: https://127.0.0.1:15080 You may also SSH into the box with the following command:

$ ssh -p 15022 ModelOp Center@127.0.0.1

You are now ready to start scoring!

Additional Information

In addition to “hello-world”, ModelOp Center OVA comes with pre-installed Gradient Boosting Machine (GBM) model example. In order to run it:

$ cd GBM
$ ./prep.sh
$ ./run.sh

Note that first run might take time since required model packages are being installed into container. To view the output of the example (gbm_output.json):

$ cd /opt/data
$ less gbm_output.json

Press q to escape.

You can start / stop / get status from / restart ModelOp Center service using the following set of commands (make sure to use “sudo”):

$ sudo service ModelOp Center start 
$ sudo service ModelOp Center stop 
$ sudo service ModelOp Center status 
$ sudo service ModelOp Center restart

Optionally, you can install ModelOp Center CLI on your host running Virtual Box. This is how you connect CLI to ModelOp Center on VM:

$ ModelOp Center connect https://127.0.0.1:15080

You can also look at these scripts:

under the GBM folder for self-explanatory CLI command examples.
