SSDBoxesCalcOfflinePass
中支持density_prior_box
:之前该 pass 只支持prior_box
;使用 facebox 模型验证的效果如下;使用固化尺寸模型后,在麒麟970手机上,opencl fp16 tune off 速度150ms;加入pass优化后速度119msSSDBoxesCalcOfflinePass
中增加约束:当 img shape 或 input shape 在 opt 阶段无法读到时,跳过本 pass;如果不跳过 pass,则因读到的 img shape 或 input shape 的 HW 维度是-1
导致在计算 prior_box 时出现段错误
