数据集有问题一般是，检查下segmentation字段符不符合格式或者直接把segm屏蔽了就行了

感谢您的回复，我当天直接把seg屏蔽了，好用了

你好，我也遇到同样的问题了，请问怎么屏蔽的seg？谢谢！

-- for me the issue was or is that I am using a LabelStudio and labeling some of my data with a Rectangle Label, and other's with a Polygon Label. -- so the CoCo outputted json file on some classes would have: "segmentation": [], "bbox": [ 29, 310, 682, 430 ], -- hence an empty segmentation array would cause the error

Solutions Tested: -- adding an empty array "segmentation": [[]], !FAILED :-1: -- remove the Rectangle BBOX labels and create the annotations with Polygon Label : !SUCCESS :+1:

hi,i also meet this error. someone says that shielding the Segm.But i don't konw revise which file and how to realize shielding the Seg. I think that the file may be nuimages_v1.0-train.json. Could you help me?
