Movidius not found when attempting to load a graph

[robert_osmosis]

Hello, I am trying to run the following code:

from inference_engine import IENetwork, IEPlugin

def debug_movidius():

    plugin = IEPlugin(device='MYRIAD')
    net = IENetwork(model='cars.xml', weights='cars.bin')



    input_blob = next(iter(net.inputs))
    out_blob = next(iter(net.outputs))


    exec_net = plugin.load(network=net, num_requests=2, config={"VPU_LOG_LEVEL": "LOG_DEBUG"})

    print(input_blob)
    print(out_blob)
    print(exec_net)



if __name__ == '__main__':

    debug_movidius()

I am running the script from the inside of a docker container which does have access to the NCStick, I am running it in privileged mode and have tested with lsusb that it does have access to them.

However this is the error I am getting:

[setupvars.sh] OpenVINO environment initialized

SOLVED:

I was installing python3.6 after installing the openvino libraries and for some weird reason it was causing openvino/python to stop recognizing the movidius sticks.

What I did to solve it was to install the openvino libraries AFTER installing python3.6

Dear Rios, Robert,

It's weird that order of installation matters but I'm glad you fixed it. Thanks for reporting back and sharing your knowledge with the OpenVino community !
