Hi I have used these function to calculate mean average precision (mAp) for a subset of google Audioset. I have run a lot of training. now I have changes my features and run a new train, but in some epochs, mAp is greater than 1 !!! I don't know what the problem is? other metrics such as hit_at_one or AUC (area under the curve) are normal. how can I solve it?

@creativesh It could a very small value that is less than 0 but displayed in exponential notation. e.g. 1.197076060995287e-05 which is about 0.00001 in normal decimal notation.
