openvino 2019 R3.1
I am getting the following error even when I source my openvino environment with the right python version (source /opt/intel/openvino/bin/setupvars.sh -pyver 2.7).
Traceback (most recent call last): File "hello_query_device.py", line 3, in <module> from openvino.inference_engine import IECore File "/opt/intel/openvino_2019.3.376/python/python2.7/openvino/inference_engine/__init__.py", line 1, in <module> from .ie_api import * ImportError: /opt/intel/openvino_2019.3.376/deployment_tools/inference_engine/lib/intel64/libinference_engine.so: undefined symbol: _ZN3tbb10interface78internal15task_arena_base24internal_max_concurrencyEPKNS0_10task_arenaE
I have updated my numpy and cython, as suggested by another thread, but nothing works.
The interesting thing is that I was not receiving this error on a freshly installed system. However, after installing ROS, and some other packages I am getting this error now.
I would appreciate any hints.
Probably you had temporarily set your environment variables which is the :
It's better if you permanently set the environment variables as the OpenVINO environment variables are removed when you close the shell
You can do it as follows:
1.Open the .bashrc file in <user_directory>
2.Add this line to the end of the file:
3.Save and close the file: press the Esc key and type :wq.
4.open a new terminal, You will see [setupvars.sh] OpenVINO environment initialized.
you can find these in here : https://docs.openvinotoolkit.org/latest/_docs_install_guides_installing_openvino_linux.html#set-the-...
Do let me know if this helps 🙂
Thank you so much for your quick response.
I am already setting my openvino environment in the bashrc. The problem is for sure not the proper sourcing of openvino, cause it would be a different error (the following) if the the source is not set.
ImportError: No module named openvino.inference_engine
I am not getting this error. I am getting the error in my original post, related to ie_api.
I still cannot solve the issue unfortunately.
Any thoughts on the potential reason behind the issue?
1) What do you see if you set your environment variables with default Python version (without -pyver 2.7)?
2) Please have a chance to try latest available OpenVINO toolkit 2020.3 release instead of 2019 R3.1.
