Hello to everyone,
I have the following error trying to execute my custom application with openvino:
symbol lookup error: /opt/intel/openvino_2020.3.194/deployment_tools/inference_engine/lib/intel64/libinference_engine.so: undefined symbol: _ZN3tbb8internal13numa_topology4fillEPi
Executing this command:
nm -D /opt/intel/openvino_2020.3.194/deployment_tools/inference_engine/lib/intel64/libinference_engine.so | grep _ZN3tbb8internal13numa_topology4fillEPi
I get the following:
My system is an Ubuntu 18.04 VM with an intel i7 6th gen, using openvino toolkit 2020.3.
Any clue on why the symbol is undefined ?
Hi Alexandre Pires,
I would suggest you try one of the following:
· Ensure that your environment OpenCV_DIR is pointing to the OpenVINO version of OpenCV (/opt/intel/openvino_2020.3.194/opencv/cmake).
This gets exported by the setupvars script, which sets your environment variables. If you do not setup for .bashrc script (to permanently set the environment variables), you'll have to setup every time for each terminal.
· If you have Anaconda installed in your system, please try reinstalling Anaconda as some community members have mentioned it as a workaround.
