How to calculate PrecisionRateAtN?

[MAX-OTW]

Hello, @iraikov , I'm sorry to bother you~Now, I have a procedural question to communicate with you:)This is the problem:
https://github.com/MubarizZaffar/VPR-Bench/blob/77ad30f3684476717188c67d7f3f66be19f832af/performance_comparison.py#L71C1-L104C1, this is the code for calculating RecallRateAtN, I would like to ask you how to calculate PrecisionRateAtN?I tried several times, but failed. Can you provide the relevant code?
note this:
Recall@N=TP@N/(TP@N＋ FN@N);Precision@N=TP@N/(TP@N+ FP@N)
Could you please help me? Hope to receive your reply soon :)
Thanks & Best Regards!
