Add an NLU model to an update set

Use update sets to move your Natural Language Understanding (NLU) models from one instance to another. Update sets include all records needed for your model to function on the target instance.

始める前に

• Make sure that the NLU Workbench plugin, NLU Workbench - Core plugin, and Predictive Intelligence plugin are all installed and activated on your instance.
• The following instructions apply to NLU models for Virtual Agent and AI Search.
• Role required: admin

このタスクについて

Use update sets to transfer a model from a source instance to a target instance. The target instance must already have the same scope as the model's scope in the source instance.

Adding a model to an update set includes the following resources:

• Model content (intents, utterances, entities, annotations, vocabulary, and the default test set)
• Associated vocabulary sources
• Corresponding latest active ML solution
• ML model artifacts
• ML solution and definition (last three runs, provided one of them was successful)

For more information on update sets, see System update sets.

If you want to add the model to a different update set, you must make that update set the current one. See Create and select an update set as the current set.

For optimum portability, add your NLU model to a new, dedicated update set rather than to a system Default update set. To do this, a new update set must be manually created in the model's scope. An error is displayed if the current update set is the scope's Default. This error contains a link for manually creating a new update set.

If the model contains records from multiple scopes, such as vocabulary tables, its update set must have a parent-child (batch) structure. Follow the procedure from step 5 to create a parent-child update set.

When models (either Global or scoped) are moved using update sets, their training and publishing state remains the same after transfer. So a model that is trained and published before it is added to an update set does not require retraining or republishing on the target instance.

For information about parent-child update sets, see Working with batched update sets. The following video provides a demonstration of this process.

手順

1. Select All and enter sys_nlu_model.list into the navigator.

   

2. Select the Model Name of the model.

   

   The Display name is the name you gave the model when creating it. The Model name is given to the model by the system.

3. オプション: If Global is your current application, follow the prompt at the top to edit the record.

   

4. In the Related Links section, click Add model to current update set.

   

   If the model's records are all in one scope, the system adds the model to the current update set. Once completed, the record can be found in the sys_update_set table.

   However, the system displays an error if the designated scope is the Default scope. Continue with the following steps.

5. If the system displays the error You are attempting to add a record to the system default update set, continue with the remaining steps in this procedure.
   

   In the error banner, select the New Local Update Set link to create a new update set which is not Default. In the case of a parent-child update set, the parent is first created in the model's scope. (Any child update sets are created in a later step).

   New Local Update Set opens a new record in the sys_update_set table.
6. For the new update set record, provide a name, review other values including Application scope, then select Submit and Make Current.
   
   A new update set is created, and the screen re-opens to the model's record in the sys_nlu_model table.
7. In the model's record in sys_nlu_model, select Add model to current update set under Related Links.
   When the model's records are in multiple scopes, this step creates child update sets that have Global scope.

   注:

   If the model's records are all in one scope, the system adds the model to the current update set. Once completed, the record can be found in the sys_update_set table.
8. If the model is in a non-Global scope: In the Update Sets table sys_update_set, locate the parent update set and its child update sets (refresh the page if necessary).
   • The parent update set has the value (empty) in the Parent column.
   • Child update sets have the name of the parent in the Parent column, and Global in the Application column.
   • Both parent and child update sets contain the same value in the Batch Base column.

   
9. Open the parent's record in sys_update_set and set the State field to Complete.
   A Confirmation dialog box pops up. Select Yes to confirm. This sets the parent and all child update sets to Complete.
10. To migrate the update set file, select Export Update Set Batch to XML in the parent's record in sys_update_set.
    The parent and child update sets are packaged together and exported.

次のタスク

In the target instance, navigate to Retrieved Update Sets and select Import Update Sets from XML. When unpackaged, the parent and all children will be listed in the Retrieved Update Sets table. Open the parent and select Preview Update Set Batch.

If a referenced record in the source instance is not present on the target instance, you may encounter errors while applying the update set. For example, the origin field on sys_nlu_intent could refer to an intent from a different model that doesn't exist on the target instance. You can click Accept remote update on the failed records to commit the update set anyway.
