Model not learning2

[JaspervDalen]

Just like drorhilman my model is not learning in a two class situation. The labels seem te be correct (I wrote a new parser outputs for example [[1, 571, 327, 479, 181]] and the correct file name). The loss starts at inf but after one batch it drops to 0 and stays there. The model however does not learn. Any ideas?

my dataset gave the ground truths as x,y,w,h where x,y is the top left of the image and not the centroid as i assumed. fixing this made the model learn
