How can I add custom new class labels, lets say-x classes to a SCL trained model( which is already trained on y classes). So I do not replace those y classes and in total I have x+y class labels.

I need to train the old objects +new objects again?or is there a way to train for only new labels.

So far it's not integrated in the code base. You will have to look for few shot object detection techniques for that.
