hi, i have problem to import python inference api in latest versions (R2, R2.01).
Python 3.6.5 |Anaconda, Inc.| (default, Apr 29 2018, 16:14:56)

>>> import openvino

from .ie_api import *
ImportError: /opt/intel/openvino_2019.2.242/python/python3.6/openvino/inference_engine/ie_api.so: undefined symbol: PyFPE_jbuf
i followed all install steps correclty including running demos and configure(<INSTALL_DIR>/bin/setupvars.sh).
it works for older versions bellow R2.01 but i need to use R2.x version to optimize BERT NLP model.

Dear kim, donggyu,
PYTHONPATH is set when you run setupvars.sh. Here is the Windows version (setupvars.bat):
set PYTHONPATH=%INTEL_OPENVINO_DIR%\python\python%Major%.%Minor%;%INTEL_OPENVINO_DIR%\python\python3;%PYTHONPATH%
echo PYTHONPATH=%PYTHONPATH%
However you're right. This error undefined symbol: PyFPE_jbuf which I missed earlier has nothing to do with PYTHONPATH. Googling around though, it has to do with numpy. In fact, this error has nothing to do with OpenVino (or Model Optimizer).
If you google undefined symbol: PyFPE_jbuf you will find several hits.
Here is a
3 year old Stack overflow post
. Three years seems like an eternity in tech but this issue could very well be related to numpy (which OpenVino does depend on, i.e. the Calibration tools and Model Optimizer).
I believe that there is something buggy with your environment. Fix that, and you won't have this issue.
Thanks,
Shubha

Dear kim, donggyu,
Your PYTHONPATH is incorrect. Whenever this fails,
>>> import openvino
>>> from openvino import inference_engine
That is the reason. Make sure PYTHONPATH is set at the
correct directory level
to be able to import openvino stuff.
Hope it helps,
Shubha
Dear, Shubha. thank you for you comment.
can you give me some more detailed instruction?
The official instruction of openVINO python api describes i can set environment as follows :
-------------------------------------------------------------------------------------------------------------------
(https://docs.openvinotoolkit.org/latest/_inference_engine_ie_bridges_python_docs_api_overview.html)
Setting Up the Environment
To configure the environment for the Inference Engine Python* API, run:
On Ubuntu* 16.04 or 18.04, CentOS* 7.4 or macOS* 10.x: source <INSTALL_DIR>/bin/setupvars.sh .
On Windows* 10: call <INSTALL_DIR>\deployment_tools\inference_engine\python_api\setenv.bat
The script automatically detects latest installed Python* version and configures required environment if the version is supported. If you want to use certain version of Python*, set the environment variable PYTHONPATH=<INSTALL_DIR>/deployment_tools/inference_engine/python_api/<desired_python_version> after running the environment configuration script.
-------------------------------------------------------------------------------------------------------------------
But i found out "PYTHONPATH=<INSTALL_DIR>/deployment_tools/inference_engine/python_api/<desired_python_version>" is not available in latest versions (there is no such directory in my installation).
So i set the path to "PYTHONPATH=<INSTALL_DIR>/python/<desired_python_version>/openvino/inference_engine" as instructed in
https://software.intel.com/es-es/node/814765
Is the above process incorrect?
In addition, i currently got import error below :
-------------------------------------------------------------------------------------------------------------------
ImportError: /opt/intel/openvino_2019.2.242/python/python3.6/openvino/inference_engine/ie_api.so: undefined symbol: PyFPE_jbuf
-------------------------------------------------------------------------------------------------------------------
As far as i know, i think this error indicates there is a problem in compiled "ie_api.so", not its path.
Thank for your comment, again.

May be a problem with numpy, but this is my mapping of native openvino to the docker container，So it may not be found, can you help me?

I solved it and the solution is as follows:
1. Copy the openvino installation package to the docker container
2. Run the ./install.sh file in the installation package
3. Select the repair option or press Enter
Hi,
I still facing the same issue it's seem:
Traceback (most recent call last):
File "/opt/intel/openvino/deployment_tools/inference_engine/samples/python_samples/classification_sample_async/classification_sample_async.py", line 25, in <module>
from openvino.inference_engine import IENetwork, IECore
File "/opt/intel/openvino_2019.3.376/python/python3.6/openvino/inference_engine/__init__.py", line 1, in <module>
from .ie_api import *
ImportError: /opt/intel/openvino_2019.3.376/python/python3.6/openvino/inference_engine/ie_api.so: undefined symbol: PyFPE_jbuf
This issue seem related to Cython and numpy. I use virtualenv, conda changed version many time but sitll block.
With Openvino 2018.*, I didn't have this issue.
Thanks for help.
I was getting this error :
from openvino.inference_engine import IENetwork, IEPlugin
File "/opt/intel/openvino_2020.2.120/python/python3.6/openvino/inference_engine/__init__.py", line 1, in <module>

ImportError: /opt/intel/openvino_2020.2.120/python/python3.6/openvino/inference_engine/ie_api.so: undefined symbol: PyFPE_jbuf
while I was trying out the smart video workshop and I tried to execute the tutorial1.py file.
cd $SV/object-detection/Python python3 tutorial1.py -i $SV/object-detection/Cars\ -\ 1900.mp4 -m $SV/object-detection/mobilenet-ssd/FP32/mobilenet-ssd.xml
l solved by simply running the setupvars.sh file using python3.5 version instead of 3.6.
source /opt/intel/openvino/bin/setupvars.sh -pyver 3.5
hi,
i was geting this error with the latest versions (openvino_2020.3.194) :

I try to solved it and the solution is as follows:
1 . updata numpy ( version==1.18.5)
2. updata cython : "python setup.py cython"
but all fail.
