Failed to detect objects with UP AI Core X

scarlyon

I am using UP AI Core X on Ubuntu 16.04. https://up-board.org/ai-core-x/

I use the latest version of OpenVINO toolkit(2019.1.133) to detect objects from the webcam.

But I sometimes get these error messages:
1.

E: [ncAPI] [    183032] ncDeviceOpen:799    Failed connection to device (3.1-ma2480) with error 5

2. Traceback (most recent call last):

Any idea?

Updated: Please ignore the 1st and 2nd one.
Just 3rd one is the problem now.
