@wangzhe0623 can you provide more information about the format of ground truth txt file and prediction txt file.
For ground truth txt file, I guess it is
For prediction txt file, is it ?

[wangzhe0623]

@kkwong95 You can check 'sample' folder for reference

[kkwong95]

Yeah, I checked the 'sample' folder before I raise up this issue.
I tried with your code with your sample txt file and It work. However, when I try to use mine, it has an error as below:

precision, recall, fppi, fppw, ap = self.computeAp(label)
ValueError: not enough values to unpack (expected 5, got 3)

My txt file's class name different from yours. My classes are 'car', 'motorbike', 'bus' and 'truck'. Is it the reason, my txt file cant run in your code ?

[wangzhe0623]

@kkwong95 Classes' name must be integer, like "0, 1, 2, 3", and it should be counted from "1".
