Is there a way to rapidly calculate the mAP for each image?

[istranic]

Hi,

I'd like to log the mAP for each image in my object detection dataset, and as far as I can tell, the only way to do that is to run metric(preds, target) after each image. This is very slow, so I'm wondering if there's a way for metric.compute() to return metrics per image without having to call it individually for each image?
