Multi ncs2 wont work on facerecognition_demo.py #3481

Closed glennford49 closed 1 year ago

glennford49 commented 2 years ago

I have tested a single ncs2 on facerecognition.py demo, and also tested two ncs2 on same facerecognition.py demo, both yield the same FPS output? Is there any way to speed up the fps value when using 2 ncs2 sticks? Tested the multi plugin MULTI:MYRIAD.xx,MYRIAD.xx, but still doesnt work

MULTI may speed up the execution, but only in some cases

  1. MULTI won't help for -d_fd because there's only one image to process at a time.
  2. MULTI helps for -d_lm and -d_reid only if there are enough faces detected on an image. Each MYRIAD stick is able to process two inference request at a time. So when you add another stick, you need to have at least three faces detected to generate enough data for landmarks and reid models to start utilizing the second stick.
