@tonghe90 我看了一下代码,发现在point_bilinear_layer.cpp中,如果每次输入的roi的个数(point_num_=bottom[1]->num())为变化的数目,这时会因为reshape时 top[0]->reshape(*)分配的内存是固定的,可能导致内存越界; 因此,我突然想到自己之前输入的roi可能是错的,输入的roi个数应该是固定的,比如100个(可能比图片实际拥有的roi个数多,也可能少),而输入的sample_id作用就是指出来输入的ROI中那些是真正存在的ROI,而那些不是真的存在的roi可能被填充0或-1,只是起到对齐内存的作用,从而避免内存访问越界;不知我的上述理解是否正确?
