1.芯片型号：J6
2.天工开物开发包 OpenExplorer 版本： J6_OE_3.0.17
3.问题定位：制作nuscenes数据集时发现bug
4.问题具体描述：
使用如下命令：

python3 tools/datasets/nuscenes_packer.py --src-data-dir data/nuscenes/ --pack-type lmdb --target-data-dir data/nuscenes/lidar/v1.0-mini --version v1.0-mini --split-name train --only-lidar

制作nuscenes数据集时出现报错：

Traceback (most recent call last): File "/open_explorer/samples/ai_toolchain/horizon_model_train_sample/scripts/tools/datasets/nuscenes_packer.py", line 60, in packer = NuscenesPacker( File "/usr/local/lib/python3.10/dist-packages/hat/data/datasets/nuscenes_dataset.py", line 2738, in __init__ self.packer_meta = self.dataset._get_meta() File "/usr/local/lib/python3.10/dist-packages/hat/data/datasets/nuscenes_dataset.py", line 2151, in _get_meta meta = {"scene_info": self.scene2len} AttributeError: 'NuscenesLidarParser' object has no attribute 'scene2len'
