我是一个新手，当我使用tools/infer.py进行多张图片模型预测时，出现以下错误：

2020-05-19 21:43:34,885-INFO: Infer iter 24
Traceback (most recent call last):
  File "tools/infer.py", line 304, in <module>
    main()
  File "tools/infer.py", line 205, in main
    x1y1x2y2_result,bbox_results = bbox2out([res], clsid2catid, is_bbox_normalized)
  File "/home/aistudio/PaddleDetection/ppdet/utils/coco_eval.py", line 270, in bbox2out
    catid = (clsid2catid[int(clsid)])
KeyError: 2

这是为什么呢，我暂时找不到原因。要是能帮到我，我真的非常感谢。
