kitti_dbinfos_train_global.npy

[GuoZhuoRan]

Hello there, I have some problem in kitti_dataset.yaml. There seems to be no code for generating kitti_dbinfos_train_global.npy, and also I can't find it elsewhere on the website, and I need some help, many thanks.

Hello, kitti_dbinfos_train_global.npy is a integrated gt_database to accelarte the gt sampling data augmentation. Actually, you can just set the USE_SHARED_MEMORY to false if you don't have or don't want to use it

SparseKD/tools/cfgs/dataset_configs/kitti_dataset.yaml

Line 27 in 8572093

USE_SHARED_MEMORY: True # set it to True to speed up (it costs about 15GB shared memory)

.

Also, you can create this by tool from existing gt database and info https://github.com/open-mmlab/OpenPCDet/blob/master/tools/process_tools/create_integrated_database.py
