Cannot load library 'libcpu_extention_avx2.so' in Edge insight for vision

Jump to solution

Hi,

I followed the instruction in get started to install edge insight for vision. The installation completed successfully, but I got an error when running single detection application on CPU.

libcpu_extention_avx2.so doesn't exist. It seems that the guide assume OpenVINO 2019.3, but 2020_R3 was installed.

I tried libMKLDNNPlugin.so instead, but I saw another error - 'undefined symbol: CreateExtension'.

May I ask for suggestion on how to solve the situation?

 

Regards,

Hi Shigeyoshi, 

Since you have OpenVINO 2020 installed, I assumed you downloaded the 2020.3 Version for the Edge Insights Vision, is this correct ?

Is it possible for you to share what else is inside your openvino/deployment_tools/inference_engine/lib/intel64/ directory ? 

Thanks.

Hi Shigeyoshi, 

In OpenVINO 2020_R3, the CPU extension is no longer needed, thus it is not in the folder. You can run the demo by removing the extension command as below to run the demo: 

$ python3 object_detection_demo_yolov3_async.py -i $HOME/Downloads/YOLOv3/Sample_videos/one-by-one-person-detection.mp4 -m $HOME/Downloads/YOLOv3/tensorflow-yolo-v3/FP32/frozen_darknet_yolov3_model.xml

You can also do the same for the Multi-Detection Application

python3 object_detection_demo_yolov3_async.py -i $HOME/Downloads/YOLOv3/Sample_videos/person-bicycle-car-detection.mp4 -m $HOME/Downloads/YOLOv3/tensorflow-yolo-v3/FP32/frozen_darknet_yolov3_model.xml

 

Thanks.
