It seems that the path is wrong, but I tried to change the .Py file path to the data file path. It still doesn't work

You can check the dir path (e.g., "./data/kitti/kitti_merge/training/calib_cam2cam", "./data/kitti/kitti_merge" and so on) to locate the path problem.

I also met this error, this is a wrong use of os.symlink since the source path is relative to the linked path, so here's how I solved it:

1. add lpcgdir = os.getcwd() at the beginning of 'link_kitti_raw.py'.
2. revise the for-loop at line 39 to

os.symlink(os.path.join(lpcgdir, img_list[i][2:]), os.path.join(image_dst_dir, base_name+'.png'))
os.symlink(os.path.join(lpcgdir, lidar_list[i][2:]), os.path.join(lidar_dst_dir, base_name+'.bin'))
os.symlink(os.path.join(lpcgdir, cam2cam[i][3:]), os.path.join(cam2cam_dst_dir, base_name+'.txt'))
os.symlink(os.path.join(lpcgdir, vel2cam[i][3:]), os.path.join(vel2cam_dst_dir, base_name+'.txt'))

(adjust the tabs yourself)

Thanks for your feedback! I will check and revise the code.
