Branch

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

Environment

torch 1.13.1+cu116 pypi_0 pypi torchaudio 0.13.1+cu116 pypi_0 pypi torchvision 0.14.1+cu116 pypi_0 pypi mmcv 2.0.0rc4 pypi_0 pypi mmdet 3.1.0 dev_0 mmdet3d 1.3.0 dev_0 mmengine 0.9.0 dev_0 mmsegmentation 1.2.1 dev_0

Additional information

1. I use the nuscenes dataset and download the data_info.pkl from official website
2. According to my previous experience I am using the v2.0 dataset format, but the code is still supported for 1.0

The same issue, and it can be solved by change img_h, img_w, _ = img_metas[img_id]['img_shape'][cam_id] to img_h, img_w = img_metas[img_id]['img_shape'][cam_id]
