Importing Annotations
Overview of importing pre-labels into Ango Hub
Ango Hub provides a way to import existing annotations to the platform. This can be useful if you are migrating from another tool or if you wish to import existing model outputs.
Your annotations will need to be converted to the Ango Hub Import Format. More information on the format can be found at this link.
How to Import Labels into Ango Hub
Only tasks in the Start stage can be pre-labeled.
By default, in new projects importing pre-labels is disabled.
You can only pre-label tasks that are in the Start stage. And by default, tasks skip the Start stage, as they are auto-forwarded to the stage following Start.
Thus, to import pre-labels, you must disable auto-forward in your Start stage. To do so, go to the Workflow tab and click on the Start stage. Then, deactivate the toggle named "Auto Forward". Then save the workflow. More details on the Start stage here.
Convert your existing labels to the Ango Hub Import Format. More information on the format here.
Ensure you have disabled Auto Forward in the Start stage of your workflow, or tasks will be automatically sent to the stage following it, preventing them from being pre-labeled.
From the Assets tab, click on the Import button.
From the dialog that pops up, click on the dashed rectangle in the middle to open your system’s file explorer and pick an import file. Alternatively, drag and drop the import file on the dashed rectangle.
By clicking on Sample JSON, you can obtain a ready-made skeleton you can use to import annotations in your project, using the labeling tools you have already added.
If the import was successful, the dialog will close and your assets will gain a blue “label” mark to indicate that they have been pre-labeled.
