Requested CNN resources overlaps with RGB camera error on Raspberry + Oak D

Platform: Raspberry Pi 4, 4Gb RAM OS: Raspbian Buster Full (2020-02-13) Board: Oak-D connected to USB 3 (blue) port, extra power is connected. test.py reports the error in subject, but Oak-1 works without issues. Log is attached. oak-d-failure.log

Best performance can be achieved w/ 14 shaves/14cmx and 2 NCEs. For that the model needs to be compiled for 7 shaves (7 shave for each NCE = 7x2=14) In depthai.py the following config needs to be changed to 14, 14, 2.

if default_blob:
    #default
    shave_nr = 7
    cmx_slices = 7
    NCE_nr = 1

It will likely exceed 30 fps, so the rgb camera fps needs to be adjusted to 40 fps (or more): -rgbf 40 If inference is requested on both left and right cameras 2 NCEs are mandatory, otherwise they won’t be balanced.

I found that root cause: left camera socket was ejected. I reconnect camera and the first device works good now.
