What does “first_match_break” in evaluators.py mean?

Hi, Tong Xiao, Thank you for your great work. There is a question about evaluation as in title. What is the difference between first_match_break==True and first_match_break==False?

Thank you very much!

On Market-1501:

the query will always match the “easiest” positive sample in the gallery while does not care other harder positive samples when computing CMC.

You can read the docs: https://cysu.github.io/open-reid/notes/evaluation_metrics.html.
