How to use images without objects as negative samples

[shallweiwei]

If I want to use many images without objects as negative samples, how should I define the COCO format or how to train it. My current training method does not seem to use these images without objects

@shallweiwei

train_dataset = dict(dataset=dict(filter_cfg=dict(filter_empty_gt=False, min_size=32)))

filter_empty_gt

(^_^) Thanks.I have solved this,it's because I made mistakes in json file.All of the background images had the same id……
