An error occurred while processing nuscenes test set data

[lda1049187465]

Hello. When I preprocess the nuscenes training data using the instructions you provided, everything is right: python tools/create_data.py nuscenes_data_prep --root_path=/root/autodl-tmp/nuscenes/trainval --version="v1.0-trainval" --nsweeps=10.

But when I run the test command:python tools/create_data.py nuscenes_data_prep_test --root_path=/root/autodl-tmp/nuscenes/test --nsweeps=10 ,The following error occurred:

====== Loading NuScenes tables for version v1.0-test... 23 category, 8 attribute, 4 visibility, 0 instance, 12 sensor, 1800 calibrated_sensor, 462901 ego_pose, 15 log, 150 scene, 6008 sample, 462901 sample_data, 0 sample_annotation, 4 map, Done loading in 6.5 seconds.
