Add experiments

The following steps describe how to add an experiment to an MLOps project.

1. In the main navigation, click Projects.

   

2. Select the project you want to add an experiment to.

3. Click the Experiments tab.

   

4. Click Add Experiment.

   

5. Click Browse to select a file to upload from your local file system. You can also drag a file onto the page to upload it to MLOps. Supported file types include Driverless AI MOJOs, H2O-3 open source MOJOs, MLflow Models, and serialized Python (.pkl) files created with the pickle module. To confirm your selection, click Upload.

   

6. After the experiment has been uploaded, enter a name and description for the experiment, then click Add Experiment to finish adding the experiment.

   

Add serialized Python (.pkl) files

When uploading a serialized Python (.pkl) file, the following details must be provided:

• Python version: Specify the Python version used in the file.

  

• Experiment framework: Specify one of the following experiment frameworks.

  • scikit-learn 0.24.2
  • PyTorch 1.9.0
  • XGBoost 1.4.2
  • LightGBM 3.2.1
  • TensorFlow 2.5.0

• Schema: Specify the schema of the experiment. You can either enter the schema manually or enter it in the JSON format.

  Add schema manually

  Specify column names and column types for the input and target columns in your experiment:

  

  Enter schema as JSON

  Manually enter the schema of the experiment. The following example demonstrates how to format the JSON schema:

    {
      "input": [
        {
          "name": "passenger_count",
          "type": "integer"
        },
        {
          "name": "pickup_longitude",
          "type": "float"
        },
        {
          "name": "pickup_latitude",
          "type": "float"
        },
        {
          "name": "dropoff_longitude",
          "type": "float"
        },
        {
          "name": "dropoff_latitude",
          "type": "float"
        }
      ],
      "output": {
        "name": "trip_duration",
        "type": "integer"
      }
    }

Export experiments from H2O Driverless AI to MLOps

The following steps describe how to export an experiment from H2O Driverless AI to H2O MLOps. For information on creating H2O MLOps deployments directly from the completed experiment page in H2O Driverless AI (DAI) using the DAI deployment wizard, see Deploy to H2O MLOps from H2O Driverless AI.

note

This section assumes that you have completed experiments available in Driverless AI to export into MLOps. For information on how to run an experiment, refer to the section on running experiments in the Driverless AI user guide.

1. In Driverless AI, navigate to the Projects page. This page lists all available projects.

2. Select a project and link an experiment to it by clicking the Link Experiment button. For more information, see the page on linking experiments in the Driverless AI user guide.

3. In H2O MLOps, verify that the experiment was successfully exported.

Import models from external model repositories

In addition to the preceding methods, models can be imported from external model repositories / registries to H2O MLOps. For more information, see Import models from external model repositories.
