📚 The doc issue

I am in the mmdetection3d directory and haven't made any modifications; I directly executed the command:

CUDA_VISIBLE_DEVICES=1 python tools/train.py mmdetection3d/configs/nuimages/cascade-mask-rcnn_r50_fpn_1x_nuim.py --work-dir res_train_1_cascade_mask_rcnn

But I received an error.
