error with crossroad_camera_demo

Hi all, recently I was playing with openVINO's samples. However, when I came to crossroad_camera_demo, it went wrong. 

I used a youtube video as an input, (https://www.youtube.com/watch?v=o2JLUWPfjbc)

and my command lines are

 

$ ./crossroad_camera_demo

-i /home/bed100/Downloads/dan-shui-de-jie-tou-yi-ren-biao-yan-diao-xiang.mp4

-m /opt/intel/computer_vision_sdk/deployment_tools/intel_models/person-vehicle-bike-detection-crossroad-0078/FP32/person -vehicle-bike -detection-crossroad-0078.xml

-m_pa /opt/intel/computer_vision_sdk/deployment_tools/intel_models/person-attributes-recognition-crossroad-0200/FP32/person-attributes-recognition-crossroad-0200.xml

-m_reid /opt/intel/computer_vision_sdk/deployment_tools/intel_models/person-reidentification-retail-0079/FP32/person-reidentification-retail-0079.xml

-d CPU

-d_pa CPU

-d_reid CPU

 

In the beginning, the result was great, everything was good, but 10 seconds later, it gave me an error.

[ ERROR ] OpenCV(4.0.1-openvino) /home/jenkins/workspace/OpenCV/OpenVINO/build/opencv/modules/core/src/kmeans.cpp:240: error: (-215:Assertion failed) data0.dims <= 2 && type == CV_32F && K > 0 in function 'kmeans' 

 

I'm wondering what causes the problem since it went well if I use my video recorded from my mobile phone instead of using online videos.

Thanks.

Hi weicheng,

It looks like you are using an outdated version of the OpenVINO Toolkit. Could you install the latest 2019 R3.1 release and see if the issue is still present?
