sagnn方位sector划分 #321

感谢代码开源~
关于sagnn模型的sector划分,我有如下问题想请教一下:
PaddleSpatial/paddlespatial/networks/sagnn.pydef get_subgraphs(self, g)中,sec_ind = int(angle / (np.pi / self.num_sectors))(第115行)是什么含义呢?
我理解的self.num_sectors是将一个整圆均分为self.num_sectors个扇区,但是(np.pi / self.num_sectors)只是将一个半圆分成了self.num_sectors个扇区。
期待您的解答~
