Hi Intel,

I am new at using OpenVino and NCS2 .. I am now trying to run the face_recognition_demo that I got from the open model zoo on windows10 .

Iam using version 2020.3 of openvino toolkit. But I get this error everytime i try to do so ( error below). I would be very greatful to you if you help me.

Thank you in advance.

Hi aicha,

Greetings to you. Did you get the model (face-detection-retail-0004) downloaded from the same version of your OpenVINO? Make sure you are using the model that you downloaded from the same version of your OpenVINO which 2020.3 and run the demo again. I've validated this on my side and everything works well.

Here is the workaround to run the demo:

1. Setup OpenVINO environment.

cd <INSTALL_DIR>\openvino_2020.3.194\deployment_tools\bin

Run setupvars.bat

2.Navigate to the face recognition demo folder

cd <INSTALL_DIR>\openvino_2020.3.194\deployment_tools\open_model_zoo\demos\python_demos\face_recognition_demo

Run pip install -r requirement.txt

3.Run the demo

python./face_recognition_demo.py -m_fd "<INSTALL_DIR>\openvino_2020.3.194\deployment_tools\tools model_downloader\intel\face-detection-retails-0004\FP16\face-detection-retail-0004.xml" -m_lm "<INSTALL_DIR>\openvino_2020.3.194\deployment_tools\tools model_downloader\intel\landmarks-regression-retail-0009\FP16\landmarks-regression-retail-0009.xml" -m_reid "<INSTALL_DIR>\openvino_2020.3.194\deployment_tools\tools model_downloader\intel\face-reidentification-retail-0095\FP16\face-reidentification-retail-0095.xml" -i 0 -fg "<IMAGE_DIR>\Pictures\image_name"

 

Check out the Interactive Face Recognition Demo documentation for more details.

Aznie

Hi aicha,

Thanks for reaching out.

From your file path, it shows that you are using OpenVINO 2021 version instead of 2020.3. Furthermore, the face recognition demo script is no longer available on the latest release OpenVINO 2021. If you want to run the demo, you should use OpenVINO 2020.3 environment. Firstly, navigate to your OpenVINO 2020.3 installation folder and initialize the environment by following these command:

 

Cd <INSTALL_DIR>\openvino_2020.3.194\bin

Setupvars.bat

Then, cd <INSTALL_DIR>\openvino_2020.3.194\deployment_tools\open_model_zoo\demos\python_demos\face_recognition_demo

Run face_recognition_demo.py -h to see the flag that needed for this demo.

 

Regards,

Aznie

Hi @IntelSupport,

Thank you for your response.

But the problem is that I get the following error when I use the 2020.3 OpenVino environment:
