Your photos are likely too big/high resolution. I would try downscaling the images before loading them in the interface.

Thanks for your suggestion. Unfortunately I have to keep them with the best quality possible, but I don't think that it's related to the pictures.
I've tried with Label Studio & CVAT to create a new project from scratch with 1 low quality picture and 10k labels and it doesn't work (or lags a lot).

It could be something with your system then.

You don't have to degrade the quality of the original images. If you create a copy of the images and downsoze the copy, you can label the copied files while maintaining a link between the name of the original file and a name of the copy.

What size are the files?

I've tried with just 1 little picture (400kb, 512*512), it's working, but when I add the 10k labels into the JSON, unfortunately CVAT, Label Studio etc. lag a lot or don't work at all (freeze).

Definitely sounds like an issue woth the amount of labels.

You could try splitting your dataset into chunks of 100 labels or 1000 labels and label that way?

Exactly, it's definitely an issue with the amount of labels.

About my use case, I've to list 100k pictures with 10k labels. For each picture, the user have to use the object detection to detect the item, then he has to annotate (by chosing one of the 10k labels of items)

Trying to figure out if there's a workaround or software that maybe could fit with my needs...
