RuntimeError: Unsupported primitive of type: PriorBoxClustered name: fc7_mbox_priorbox


I am trying to run the from the PyCharm using the openvino library which I installed as follows:


conda install openvino-ie4py -c openvino


Then I try to run the script using the following command:


python -m_fd C:\Users\ShraddhaM\PycharmProjects\OpenVinoStreamlit\face-detection-retail-0004.xml

 -m_lm C:\Users\ShraddhaM\PycharmProjects\OpenVinoStreamlit\landmarks-regression-retail-0009.xml -m_reid C:\Users\ShraddhaM\PycharmProjects\OpenVinoStreamlit\face-reidentification-retail-00

95.xml --verbose -fg "C:\Users\ShraddhaM\PycharmProjects\OpenVinoStreamlit\faces_gallery"


After running this command, I get the following error:
