python samples

[Morishige__Akihito]

When I run the python samples, error is occures as follows.

    from openvino.inference_engine import IENetwork, IEPlugin
ImportError: No module named 'openvino'

How do I download the openvimo module ?

Hi Akihito,

You may want to try setting up the OpenVINO environment variables:

source /opt/intel/computer_vision_sdk/bin/setupvars.sh

If that doesn't work then can you answer the following questions:

1.)What version of OpenVINO are you using?

2.)What is the command that you are using to run the sample?

Kind Regards,

Monique Jones

Yes, indeed, this is the typical error you get if you don't source setupvars.sh .  After sourcing runs fine here in R3,

 After sourcing setupvars.sh, sample works well.

Thanks a lot.

I have the same problem but source setupvars.sh doesn't eliminate the problem. It is strange since I didn't have this problem but after I did a reboot and source the setupvars.sh the script which woked fine before now it gives me this:

movidius@movidius-desktop:~/intel/ncappzoo/caffe/vgg16$ ./source_setupvars.sh

The following steps helped to get rid of all the errors and eliminate some extra steps:
1st step:
sudo rm /usr/bin/python
sudo ln -sfn /usr/bin/python3.5 /usr/bin/python
 
2nd step in .bashrc add these lines:
source /home/movidius/intel/computer_vision_sdk/bin/setupvars.sh
echo PYTHONPATH=$PYTHONPATH

So, now I don'’t have to worry what version of python is used because I forced it to 3.5 and is there every new terminal I open.
The source of setupvars.sh in .bashrc eliminates the step of sourcing every time you are in a new terminal.

Hi, I'm run openvino demo：

python3 object_detection_demo_yolov3_async.py --labels /home/pi/Downloads/OpenVINO-YoloV3-master/coco.names -i /home/pi/Desktop/20190413_092723A.mp4 -m /home/pi/Desktop/frozen_darknet_yolov3_model.xml -d MYRIAD --cpu_extension /opt/intel/openvino/deployment_tools/inference_engine/lib/armv7l/libcpu_extension.so 

error：

Traceback (most recent call last):
  File "object_detection_demo_yolov3_async.py", line 27, in <module>
    from openvino.inference_engine import IENetwork, IEPlugin
ImportError: No module named 'openvino'

How to solve it? 

Thank you！
