Data orgainization
We organize the dataset by sensors and split unlabeled data into three different scales. Users can conviently choose which part of data to download according to different training intensions. Tar files larger than 20G are split into multiple files by linux split command with parta* extensions.

After downloading desired part of data, user should put all downloaded files into the SAME folder discarding the formor folder structure. For example, both train_infos.tar, train_lidar.tar and train_cam0[1356789].tar should put in the same folder. After concatenation and extraction, file structure under data root directory is something like this
data_root
