Thanks for your great job! I want to know the size of the square anchor in 4.2 section. In addition, Is OTA sensitive to the size of the anchor?

@fan945327815 The anchor size is set to 8 * fpn_stride. And OTA is not sensitive to the size of the anchor. But may be sensitive to the number of anchors per location (may affect the hyper-params in Dynamic K Estimation).
