  1. Go to the ML Packages page.
  2. Select UiPath Document Understanding if it's a Document Understanding model.

Note: Make sure that once imported, languageVersion and the language of the imported version is the same as the one mentioned in the import package's metadata.json file. If the version is not the same, run the following query:

update [ml_package_versions] set language_version =<import_package_metadata's_language_version>
and set ml_package_language =<import_package_metadata's_ml_package_language>
where id =<imported_package_id>
