Cloning a Model Group from Version History

Clone from version history to create a new model group in Data Science from the selected model group version history and update the history's latest model group version.

  • See Before You Begin.
    1. On the Projects list page, select the project that you want to add the model group to. If you need help finding the list page or the project, see Listing Projects.
    2. On the project details page, select Model Group.
    3. From Actions (under the Search and Filter text box), select Create Model Group.
      The Create Model Group page opens.

    1. Basic information

    Select Clone from Model Group History.

    2. Add Model Group details

    Provide identifying information for the model group.

    • Name (Optional): Enter a unique name (limit of 255 characters). If you don't provide a name, a name is automatically generated.
    • Description (Optional): Enter a description (limit of 400 characters) for the model group.
    • Compartment
    • Upload an artifact file: If you're creating a model group of type HOMOGENOUS, then use the upload artifact option to upload the model group deployment runtime artifact.
    • Tags (under Advanced options) (Optional): Add tags to the model group. If you have permissions to create a resource, then you also have permissions to apply free-form tags to that resource. To apply a defined tag, you must have permissions to use the tag namespace. For more information about tagging, see Resource Tags. If you're not sure whether to apply tags, skip this option or ask an administrator. You can apply tags later.

    3. Add Model

    Add models to the model group.

    • Select from compartment list: Select the compartment that contains the project that includes the models that you want to add to the model group.
    • Select from project list: Select the project that includes the models that you want to add to the model group, then select the models from the list.

    4. Add Model Group Version History

    Select the model group version history that you want to use to create the new model group.

    • Use existing model group version history
      • Select from compartment list: Select the compartment that contains the project that includes the existing model group version history that you want to add to the model group.
      • Select from project list: Select the project that includes the existing model group version history that you want to add to the model group, then select the model group version history from the list.

    5. Model group configuration

    Select the classification type for the model group.

    • Homogenous
    • Heterogeneous
    • Stacked Inferencing
      • Base Model OCID

    Review and create

    Review the configuration and then select Create.

  • Clone the Model Group from the latest version of the Model Group version history: 
    def __clone_from_model_group_version_history(compartment_id, project_id, model_group_version_history_id):
    print("cloning from the Model Group Version History")

    "modelGroupCloneSourceDetails" : {
        "modelGroupCloneSourceType": "MODEL_GROUP_VERSION_HISTORY",
        "sourceId": "ocid1.notreviewedplaceholder.oc1.<ocid>",
        "modifyModelGroupDetails": {

        },
        "patchModelGroupMemberModelDetails": {
            "items" : [
                {
                    "operation":"INSERT",

                        },
                        {

                }
            ]
        }
    }

    2. Update the Model Group: 
      {
    "displayName": "updated display name -1 ",
    "description": "update test-1",
    "modelGroupVersionHistoryId": "ocid1.notreviewedplaceholder.oc1.<ocid>",
