在运行python tools/datasets/generate_dynamic_masks.py时报错，谁能帮帮我？

#7
Go to the following file:
VO_Module/droid_slam/data_readers/vkitti2.py
At lines 91-92, you need to change the path for panoptic_gt_id folder.
The exact replacement is:
segments = sorted( glob.glob(osp.join("datasets/Virtual_KITTI2/ALL_15-deg-left", 'panoptic_gt_id/*.png')))

Hope this helps
