Hi. I have wrote a detection algorithm. Does any one know how to calculate the **mAP** criterion? Is there any module in python to calculate the **mAP**?

Thanks.

see https://github.com/pytorch/tnt/pull/21 they have recently merged mAP meter.

You cannot make mAP a criterion (i.e. differentiable) as it’s not a differentiable cost.

Oh Sorry I did not want to mean mAP as a Criterion (differentiable Layer). I just wanted to find an exact implementation of that as metric.

On the other hand, I want to say that we can find an exact implementation of `mAP`

specifically for each dataset. Since I benefited from `MSCOCO Detection Dataset`

, the author of `MSCOCO`

present a good module in python to measure this metric.

By the way thanks for your response!
