When I am trying to execute this code, I've found an error below:

Are you sure that the openvino package is installed correctly, try running pip freeze and see if its there.

After installing the Rasbian Package, I've run the demo of face detection, and it worked. I think the OPENVINO is installed correctly.

Hi AndyDang,

Thanks for reaching out to us.


For your information, nGraph module is not included in the OpenVINO™ Toolkit for Raspbian OS Package.

In order to import the nGraph module, you have to build Open Source OpenVINO™ Toolkit for Raspbian OS.


The steps for building Open Source OpenVINO™ Toolkit for Raspbian OS is available at the following article:
