NCS 2 behaves weird, while NCS 1 is more reasonable.

  • NCS 2 wouldn't be detected correctly by NCSDK example hello_ncs_py
➜ hello_ncs_py lsusb ...... Bus 001 Device 007: ID 03e7:2485 Intel Movidius MyriadX ...... ➜ hello_ncs_py python hello_ncs.py D: [ 0] ncDeviceCreate:307 ncDeviceCreate index 0 D: [ 0] ncDeviceCreate:307 ncDeviceCreate index 1 D: [ 0] ncDeviceOpen:523 File path /usr/local/lib/mvnc/MvNCAPI-ma2480.mvcmd W: [ 0] ncDeviceOpen:527 ncDeviceOpen() XLinkBootRemote returned error 3 Error - Could not open NCS device.

 

  • C++ object_detection_sample_ssd failed to run.

Program hangs here and quit automatically on my Raspberry Pi4, but working fine on my laptop.

 

 

Can anybody take a look at it?

 

Thank you very much...

Hi Pei,

 

Thanks for reaching out.

  1. It seems you are using the Intel® Movidius™ Neural Compute SDK with the Intel® Neural Compute Stick 2, you can check here the supported SDKs for both Intel® NCS. If you want to use the Intel® NCS2, you will need to transition from the NCSDK to the OpenVINO™ toolkit, you can check how to in this guide.
  2. We tested the sample and it ran successfully with the following command:

./object_detection_sample_ssd -i TEST.jpeg -m face-detection-adas-0001.xml -d MYRIAD

Remember to use the xml file from the R3 2019 version of OpenVINO™ toolkit with its corresponding .bin file.

 

Do you have a fresh installation of Raspbian OS? You can try to reinstall its OS, test it again and tell us if it works.
