• [X] The bug has not been fixed in the latest version (dev-1.x) or latest version (dev-1.0).

Task

I'm using the official example scripts/configs for the officially supported tasks/models/datasets.

Branch

main branch https://github.com/open-mmlab/mmdetection3d

Environment

When I was preprocessing the nuscense dataset, I encountered this issue. My environment (ubuntu20.04 cuda11.4) is capable of running the KITTI dataset and successfully running the code.

Traceback (most recent call last): File "tools/create_data.py", line 340, in create_groundtruth_database('NuScenesDataset', args.root_path, File "/mnt/2206b677-3750-478c-b7c0-489c4f8ede41/cjy/mmdetection3d/tools/dataset_converters/create_gt_database.py", line 244, in create_groundtruth_database points = example['points'].numpy() AttributeError: 'LiDARPoints' object has no attribute 'numpy'

It should be an environmental issue. Today, I reinstalled the MMDetection3D environment (as described in the document) and ran it again python tools/create_data.py nuscenes --root-path ./data/nuscenes --out-dir ./data/nuscenes --extra-tag nuscenes --only-gt-database Then we can handle it correctly😭 应该是环境的问题，我今天重新安装了MMDetection3D的环境（按照文档描述），重新运行 python tools/create_data.py nuscenes --root-path ./data/nuscenes --out-dir ./data/nuscenes --extra-tag nuscenes --only-gt-database 后就可以正确处理了😭
