test.py 运行报错：Format of lanes error

[hwang12345]

使用1080p图像数据集训练模型，训练完成后使用test.py进行测试，运行报错：
merge test_model config
merge test_work_dir config
start testing...
use_aux:false
init cls

File "/home/hw/project/LaneDetection/ultra-fast-lane-detection/evaluation/tusimple/lane.py", line 31, in bench
raise Exception('Format of lanes error.')
Exception: Format of lanes error.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

这个问题应该如何解决？
