Unable to Publish NLU Models in San Diego, as it requires the application "NLU Workbench - Advanced Features", but the NLU Model can also be published via the Virtual Agent Designer without this applicationDescriptionIn Rome, you could publish the NLU Model via the NLU Workbench, but in San Diego, it is no longer possible to publish the NLU Model via the NLU Workbench, unless you have the application NLU Workbench - Advanced Features installed. However, you can still train, test and publish your NLU Model via the Virtual Agent Designer application without this application installed. In Utah, the Publish button can be found in the "Test your model" phase, which does not require the NLU Workbench - Advanced Features application.InstructionsIn Rome, you could train, test and publish the NLU Model via the NLU Workbench, as follows - In San Diego+, you can only train and test the NLU Model in the NLU Workbench. However in Rome+, can you also train, test and publish the NLU Model via the Virtual Agent Designer application without having the application NLU Workbench - Advanced Features installed. In San Diego+, the Publish your model feature is now on the NLU Model Overview page, which is "greyed out" if the application NLU Workbench - Advanced Features is not installed. One of the advanced features is that we optimize the NLU Model to reduce the percentage of incorrect predictions and/or increase the percent of correct predictions, which does not happen when you publish the NLU Model via the Virtual Agent Designer, and it will be published without the optimization. NOTE: In Utah, the Publish button can be found in the "Test your model" phase, which does not require the NLU Workbench - Advanced Features application. If the Publish button is not active after training the NLU Model, please keep training the NLU Model and track it via the [ml_solution] table until the trained version is higher than the published version, which is the active [ml_solution] record. You can check the versions of the NLU Model using table [sys_nlu_model_status]. We recommend installing NLU Workbench - Advanced Features application, as it will reduce the time in your NLU Model development cycle, but it is not a required application to create, train, test and publish NLU Models on the ServiceNow Platform, as you can also publish the NLU Models via the Virtual Agent Designer application
