使用detectron2 训练panoptic-deeplab时，解析中的数据没有 'pan_seg_file_name'，“segments_info”，只有sem_seg_file_name，报错如下：
File "/home/sun/venvT1_10/lib/python3.7/site-packages/detectron2/projects/panoptic_deeplab/dataset_mapper.py", line 101, in call
pan_seg_gt = utils.read_image(dataset_dict.pop("pan_seg_file_name"), "RGB")
KeyError: 'pan_seg_file_name'
register_coco_panoptic_separated()函数相关变量设置如下
panoptic_name = 'coco_2017_train_panoptic_separated'
image_root = 'datasets/coco/train2017'
panoptic_root = 'datasets/coco/panoptic_train2017' #全景数据
panoptic_json = 'datasets/coco/annotations/panoptic_train2017.json'
sem_seg_root = 'datasets/coco/panoptic_stuff_train2017' #语义分割数据
instance_json = 'datasets/coco/annotations/instances_train2017.json'
不知设置的是否正确
targets = self.panoptic_target_generator(rgb2id(pan_seg_gt), dataset_dict["segments_info"])
