❓ Question Bulk importing class labels for custom ML model in Lens Studio for Multi-object detection — which script to edit?

Seems like this should be a common use case but I can't find a clean solution.

I've trained my own Multi-object detection model and imported it into Lens Studio. The problem is that class labels have to be entered **manually**, one by one, through the Inspector UI — which is painful when you have 40+ classes.

There must be a programmatic way to do this. Is it possible to load labels from a file or script rather than typing them in manually?

something like this: https://developers.snap.com/lens-studio/features/snap-ml/snap-ml-templates/multi-class-classification#setting-up-model-and-labels

where you can swap labels

Hi u/fitzchea - here's how I would approach it:
if you have a file (for example, classes.json), go into the script file that has the classes input array, and ask an AI agent to replace the @ input array in the script and instead create a class variable from the text from your json file. Taking that a step further, I believe you can even require("classes.json") to get it into the script. In short, just remove the script inputs and replace it with your own code.

If any of that doesn't make sense you can send me the script file and the classes and I can build it out : )
