I've just installed openvino toolkit.
During installation verification scripts run successfully.
when I try to run python demos I got this:
[setupvars.sh] OpenVINO environment initialized
(base) ...:/opt/intel/openvino/deployment_tools/inference_engine/demos/python_demos/human_pose_estimation_3d_demo$ python human_pose_estimation_3d_demo.py
Traceback (most recent call last):
File "human_pose_estimation_3d_demo.py", line 19, in <module>
ImportError: /opt/intel/openvino_2020.2.120/deployment_tools/inference_engine/lib/intel64/libinference_engine.so: undefined symbol: _ZN3tbb8internal13numa_topology4fillEPi
Thanks in advance!

Please verify that you have Set the Environment Variables before running OpenVINO applications.
If the issue persists, try uninstalling previous versions of OpenVINO, if any.
Thank you for your answer!
The Environment Variables had been set. ([setupvars.sh] OpenVINO environment initialized).
I reinstalled OpenVINO and went back to 2020.1.
Now I got this:
undefined symbol: _ZN3tbb8internal13numa_topology11nodes_countEv
just like in this thread:
I had to reinstall anaconda like others others suggested, and now it is finally working.
There is a simpler solution.
This error indicates that OpenVINO cannot locate TBB. Just add the full path to TBB lib directory to LD_LIBRARY_PATH and that error would be gone, even without reinstalling.
