KeyError while using compare_to_groundtruth

[amitbcp]

Hi,

I am was trying to generate results on MOT16 challenge results and used mm.utils.compare_to_groundtruth to get the accuracy but resulted in error.

df_gt = mm.io.loadtxt('MOT16/preds/MOT16-01/gt/det.txt')
df_test = mm.io.loadtxt('MOT16/preds/MOT16-01/gt/pretrained_pred.txt')
check = mm.utils.compare_to_groundtruth(df_gt, df_test, 'iou', distth=0.5)

ERROR

I have same problem. did you solve?

[amitbcp]

@yunseung-dable I removed a couple of metrics and it worked fine. Was not able to corner out the issue

Same problem, when the customer ID is some specific number, it will reprot error
