I have placed the dataset correctly , but met this problem when I run gen_mini_batches.py. How can I solve it?Thank you very much!

I also met this problem. Have you solved this problem yet?

The same problem. Anybody solved it?

I solved this problem. I printed the point cloud variable and found it was empty, and I also found some files in the "/avod/data/mini_batches/iou_2d/kitti/train/lidar/Car[ 0.5]" weren't generated. So I checked the code and it told me one file in the "~/Kitti/object/training/velodyne" is broken. Therefore, I extracted the /velodyne again. The problem is solved. I think that might help you guys. Good luck!
