时间分析

Mask R-CNN 的推断过程包含以下几个步骤,我们在一些可能是瓶颈的位置增加了时间统计:

注意:mask post-processing 的时间包含在 roi_head 里,所以减少 mask post-processing 的时间就是在减少 roi_head 的时间。

使用标准尺寸测试(1333x800)

测试图片:

stage pre-processing backbone rpn_head mask forward mask post-processing roi_head total
inference 13.45 24.87 10.16 3.84 15.74 23.49 72.3
inference_fp16 13.53 15.98 8.34 3.36 15.74 22.97 61.4
inference_fp16_preprocess 1.75 15.91 8.21 3.33 15.61 22.69 49.03
inference_raw_mask 1.65 15.93 8.34 3.36 1.74 8.89 33.45

使用较大尺寸测试(3840x2304)

stage pre-processing backbone rpn_head mask forward mask post-processing roi_head total
inference 128.44 187.24 69.96 6.01 173.72 183.95 569.92
inference_fp16 127.28 120.10 50.30 6.80 172.42 186.81 485.04
inference_fp16_preprocess 11.02 120.20 50.18 6.82 174.62 187.07 379.00

可视化

mmdet 原版:

加速版:

目测没有显著差异。

总结

  • 使用 wrap_fp16_model 可以节省 backbone 的时间,但是不是所有情况下的 forward 都能节省时间;
  • 使用 torchvision.transforms.functional 去做图像预处理,可以极大提升推断速度;
  • 使用 FCNMaskHeadWithRawMask,避免对 mask 进行 resize,对越大的图像加速比越高,因为 resize 到原图大小的成本很高;
  • 后续优化,需要考虑 backbonerpn_head 的优化,可以使用 TensorRT 进行加速。

原理分析

fp16

把一些支持 fp16 的层使用 fp16 来推断,可以充分利用显卡的 TensorCore,加速 forward 部分的速度。

参考链接:https://zhuanlan.zhihu.com/p/375224982

在 backbone 上,时间从 24.87 降到 15.93,在大图上从 187.24 降到 120.26,提升 35% 左右。

torchvision.transforms.functional

使用 pytorch 的 resize、pad、normalize,可以利用上 GPU 而不是 CPU。我们在推断过程中,CPU 利用率始终是最高的,而 GPU 利用率几乎没有满过,所以只要能够把 CPU 的事情交给 GPU 做,就能解决瓶颈问题,减少推断时间。

由于整个过程都可以使用 GPU,所以时间从 13.45 降低到 1.65,在大图上从 128.44 降低到 11.03,提升 10 倍左右。

FCNMaskHeadWithRawMask

首先我们看看 mmdet 处理的结果格式:

可以看到,有多少个 bbox,就有多少个 segm,每个 segm 都是原图尺寸。不管是 CPU,还是内存,都需要大量的时间去处理。

然后再看看 FCNMaskHeadWithRawMask 处理的格式:

每个结果都是 28x28 的,这也是模型原始输出,所以信息量和上面是一样的。

唯一的区别是,我们在拿到结果之后,如果要可视化,需要 resize 到 bbox 的大小,参考 detect/utils_visualize.py#L36-L40

使用 FCNMaskHeadWithRawMask 可以从 15.74 降到 1.74,大图可以从 173.72 降到 2.99,也就是说,图越大,这个加速比越大。
