About inferrence time of cascade-GwcNet

[gangweiX]

In your paper, cascade-gwc is faster than gwcnet, however, my test time of your code is 500ms, gwcnet is 320ms.
In your cascade-gwc, firstly, constrct cost volume at 1/4 resolution(12H/4W/4), and then at 1/2 resolution, (12H/4W/4).

About Flops,
I test Flops of cascade-gwc is more than four times than gwcnet?
