Hello,

When running the PointPillars object detection example, in training mode, I notice that the results for the AP and AOS are the same, to five decimal places. I believe that they are different metrics and are calculated differently - I find it hard to believe that this is a fluke. So I ran the code six times from 10 to 60 epochs and although the AP and AOS improved at each stage, the AP and AOS result for each stage was the same, to five decimal places. Why is this so?
