cxcy_to_gcxgcy function return nan values

Open anesh-ml opened this issue 4 years ago • 6 comments

I traced back where the nan is coming from the loss function. It leads to cxcy_to_gcxgcy function. Division is causing nan value it seems. please provide any solution for this.

In my observation, it may happen when mis-order for bbox. BBOX usually places with order [left-top(x),left-top(y), right-down(x), right-down(y)], but nan will occur with [right-down(x), right-down(y), left-top(x),left-top(y)].
