Symbol lookup error when running the demo program

[Kan__Jacob]

Running environment:

CPU: Core i5 7th Gen,

OS:    Ubuntu 18.04

Encounter Symbol lookup error when I run any of the demo program. But the verification scripts in /opt/intel/openvino/deployment_tools/demo works well.

The error shows like:

./smart_classroom_demo: symbol lookup error: ./smart_classroom_demo: undefined symbol: findPlugin
 

I have done the source and environment variable setting with:

Source

source /opt/intel/openvino/bin/setupvars.sh
export

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/intel/openvino/deployment_tools/inference_engine/samples/build/intel64/Release/lib

Do you have any previous versions of OpenVINO. If yes, please uninstall them and run the demo.

Can you provide the complete logs. so that we can further have a look.

Are you using the latest OpenVINO(2020.2) version?
