Intel NCS2: Error on Build and Run Object Detection Sample of Raspberry Pi on Odroid XU3

[idata]

Hi,

I am trying to make Intel NCS2 works on my Odroid XU3 board (https://hardkernel.com/shop/odroid-xu3/) with Ubuntu 16.04.

I followed the "Install OpenVINO™ toolkit for Raspbian* OS" and see how far I can go.

It was ok until the step "Build and Run Object Detection Sample".

I understand Intel NCS2 may not support Odroid XU3 at all, however, I decide to give it a go.

I am sharing some warning and error I got, hopefully someone can provide some advice to work around these issues.

Thanks,

Lei

Here are some details

I don't know much about open vino but did you installed ncsdk api?

As far as I know ncsdk is supporting Ubuntu 16.04 so you couldn't have any trouble. Anyways I would suggest you to clone the repository of ncsdk v2 and do "make install" and "make run" inside the folder

Hi @lx2u16

The installation scripts for OpenVINO are for a Raspberry Pi running Raspbian Stretch. The demos are likely not running because it can't find the specific libraries.

Also, @tw1xy thank you for your suggestion. But the NCSDK is not supported on the NCS2. The only software kit that can be used with the NCS2 is OpenVINO :smile:

Please let me know if you have any further questions!

Sincerely,

Sahira
