ValueError: not enough values to unpack (expected 10, got 1)

[YuhanZhou521]

在运行代码 for iter_data in data:
(
sweep_imgs,
sweep_sensor2ego_mats,
sweep_intrins,
sweep_ida_mats,
sweep_sensor2sensor_mats,
bda_mat,
sweep_timestamps,
img_metas,
gt_boxes,
gt_labels,
) = iter_data[:10]时出现ValueError: not enough values to unpack (expected 10, got 1)的报错，请问如何解决
