KeyError: 'Cyclist'

here is the error when I use the detection module to train.
Traceback (most recent call last):

What should I do?

[reynerliu]

Here is my command: python train.py --cfg_file cfgs/det_model_cfgs/centerpoint_1sweep.yaml

[superkoma]

Have you finished the ground-truth sampling data creation before?

[reynerliu]

Yes,I use the command to create gt-data---‘python -m detzero_det.datasets.waymo.waymo_preprocess --cfg_file tools/cfgs/det_dataset_cfgs/waymo_one_sweep.yaml --func create_waymo_database’，and generate the file <gt_database_train_sampled_1_sweep_1>,I tried to delete the class_name 'Cyclist' in centerpoint_1sweep.yaml,the keyError disappeared,but new error broke.
