    from mmdet3d.datasets import NuScenesDataset_R
ImportError: cannot import name 'NuScenesDataset_R' from 'mmdet3d.datasets' (/home/coop8/anaconda3/envs

我们发现该函数的命名为NuScenesDatasetRC

from mmdet.datasets.builder import build_dataloader

from .custom_3d import Custom3DDataset

于是我们将from mmdet3d.datasets import NuScenesDataset_R改为from mmdet3d.datasets import NuScenesDatasetRC as NuScenesDataset_R即可
