X_LINK_DEVICE_NOT_FOUND error

tbarr7 — Wed, 21 Aug 2019 22:10:29 GMT

Hello

I have an error : ncDeviceOpen:672 Failed to find suitable device, rc: X_LINK_DEVICE_NOT_FOUND in 2 different CPU (Raspberry PIn 3B and ODROID XU4 and NC2) with several OPENVINO samples.

The problem only occurs if I have more than 1 model to load when loading the following models.

There is no error with examples that have only 1 model.

the problem only appears with the version "l_openvino_toolkit_raspbi_p_2019.1.144.tgz" NOT with "l_openvino_toolkit_raspbi_p_2019.1.094.tgz" version.

After some research, if I replace the directory "/opt/intel/openvino/deployment_tools/inference_engine/lib/armv7l" by the one of the "l_openvino_toolkit_raspbi_p_2019.1.094.tgz" version, the problem disappears.

Do you have any idea what the problem is?

Thanks Thierry

Hi Thierry,

Can you please update to the latest version of OpenVINO R2.0.1 here and try again?

Sincerely,

Sahira

Hi Thierry,

Install OpenVINO for Raspbian Stretch here. The installation instructions are listed here.

Sorry, earlier I linked OpenVINO for other Linux based platforms (which is probably why you got an error saying that version does not support IA 32 architecture).

Please install OpenVINO for Raspbian Stretch and let me know if you are still running into problems.

Best Regards,

Sahira

Hi Sahira,

I installed the R2.01 version unfortunately it doesn't have the example I use: security_barrier_camera_demo, and I couldn't compile an old version with the R2.01.

Best regards

Thierry

Hi Thierry,

You can find the security_barrier_camera demo in the Open Model Zoo here.

Hi Sahira,

It's perfect with this version tank you very much, everything works now.

Do you know if there is an example in python + NCS Myriad for facial recognition (face detection + face matching) ?

Best regards

Thierry

Hi Thierry,

At this time there are no OpenVINO samples in Python for facial recognition.

Sahira
