How to process the dataset?

[Git-oNmE]

I run the command sh scripts/train_kitti_det.sh, and I got the error message like this:

Seems like I didn't process the data files rightly.

I see it in the readme.md that the files should be organized like this:

But I don't know how to come to this. Mine is just like thiis:

Someone help me please? Thanks!

The lists of each dataset in this repo only provide refined ground truth transformations. You need to download the original dataset. The website is listed below: KITTI: http://www.cvlibs.net/datasets/kitti/eval_odometry.php NuScenes: https://www.nuscenes.org/nuscenes#download After downloading, you should organize the dataset as described in the README.

I went to the website and see several download links, could you tell me which items to download please? Thanks :)

You should download the velodyne laser data, calibration files and ground truth poses.

Thanks for your timely and useful reply!
