[OpenVINO] Using Plugin for CPU device while executing python api for Inference Engine

[GMath7]

Hi,

I am trying to execute object_detection_demo_ssd_async.py provided along with the OpenVINO toolkit. While trying to execute the same, I am getting an error, when CPU plugin is being used. Path of CPU plugin is provided as an argument. Adding the command used for executing the same below

python3 object_detection_demo_ssd_async.py -m /opt/intel/computer_vision_sdk/deployment_tools/intel_models/face-detection-adas-0001/FP32/face-detection-adas-0001.xml -i <Path to input test video> -l <OPENVINO_INSTALL_DIR>/inference_engine/lib/ubuntu_16.04/intel64/libcpu_extension_sse4.so --pp <OPENVINO_INSTALL_DIR>/inference_engine/lib/ubuntu_16.04/intel64/libMKLDNNPlugin.so

The error I am getting is unreognized arguement. Could you please help me solve the issue. I am able to execute the script excluding the argument for plugin directory.

regards,

Gina

Face-detection-adas only work with 'Interactive face detection' ,Try this with 'Interactive face detection' ,use face-detection-retail-0004 with obj_ssd

Ok. But how to explicitly add CPU plugin in command line as argument and could you please specify the plugin directory

Hi Gina,

The issue in the command line which You are post above is that -pp points to the libMKLDNNPlugin.so but according to the sample help -pp option is a "Path to a plugin folder". So just specify it like --pp <OPENVINO_INSTALL_DIR>/inference_engine/lib/ubuntu_16.04/intel64.

The general comment is that in common case you have not to specify plugin path in command line for a samples. It will be found automatically if the folder with target plugin library and all plugin dependencies  are in LD_LIBRARY_PATH. You can add it manually or just run setupvars.sh script as described in documentation, which is simpler and more preferable.
