I need to train the negative sample, the negative sample format is shown above, category_id:0, segmentation:[]
but it is wrong ,
So what should I write in negative sample format?

Write nothing. Provide no annotations for images that have no annotations. https://detectron2.readthedocs.io/en/latest/tutorials/datasets.html has mentioned this.

@shining-love just do what he says, just provide images with no annotations and do cfg.DATALOADER.FILTER_EMPTY_ANNOTATIONS = False
