What's the behavior for segment "overlap" is true, but the dataset annotation exists some overlapping objects?

Question

For my understanding. Training the segment model we have a option "--no-overlap".

• If overlap is true, then mask groundtruth will be like this: 0 0 0 0 1 1 0 1 1 0 1 1 0 1 1 0 2 2 0 0 0 2 2 2 0 0 0 0 2 0 0 0 0 0 0 0 This is for 2 classes and 3 objects in one array(1,H,W).

• In the same case, if overlap is false, then mask ground truth will be like this: Total binary array (3,H,W) First 0 0 0 0 1 1 0 0 0 0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Second 0 0 0 0 0 0 0 1 1 0 0 0 0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Third 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 0 0 0 1 1 1 0 0 0 0 1 0 0 0 0 0 0 0

So, my question is if we have indeed overlapping annotations, what will it go if overlap setting is true?

@p890040 Thanks for your hint. I have a dataset in which one class will always cover the other class. I have to set --no-overlap=True to make it work.
