hello there... am using openVINO with raspbian and NCS and its working fine..but i cannot able to use opencv withit...

it shows error:

cv2.error: OpenCV(4.0.0) /home/pi/opencv/modules/dnn/src/dnn.cpp:2538: error: (-2:Unspecified error) Build OpenCV with Inference Engine to enable loading models from Model Optimizer. in function 'readFromModelOptimizer'

will you tell to build opencv with inference engine.

Thanking you

@dilli24, that means you try to use OpenCV which is not from OpenVINO. Check output from print(cv.__file__).

@supra56 i also using pi 3b+...i used the intel official raspbian link only..but i cannot use the last demo that using opencv script..

@dilli24, What the output of print(cv.__file__)? It should be something like /path/to/inference_engine_vpu_arm/python/python3.5/ BTW there is only python3 bindings. Do you use python3 to run a script?

@dkurt home/pi/.virtualenvs/cv/lib/python3.5/site-packages/ this is my output...i installed opencv can i build opencv with inference engine..? yes i run script inside my virtualenv and using python3..?

thanking you...

how can i build opencv with inference engineDo you really need to build OpenCV with IE support? You can use one from OpenVINO package. If you want to rebuild it - read a guide: .

OpenCV is a part of OpenVINO toolkit so you can use prebuilt OpenCV libraries from it. There is no need to recompile it.
