Hi, I am trying to use Python 3.6+ with OpenVINO on Ubuntu 16.04 (which comes with Python3.5 in default). I installed OpenVINO 2019R1.1 using install_gui.sh. I noticed that in the folder /opt/intel/openvino_2019.1.144/python/python3.7, there is no cv2-cpython-xxx.so file. The only available binding so file is in python3.5 folder. Is there a way to create a binding with python and OpenCV optimized by OpenVINO?
Thanks!

You should build OpenCV yourself with Python 3.7. However, you can try to copy cv2*.so from python3.5 to python3.7 directory and rename it correspondingly.

I am facing this error when i try to import opencv after copying the /home/pi/openvino/inference_engine_vpu_arm/python/python3.5/cv2.cpython-35m-arm-linux-gnueabihf.so file to my python3.7/site-packages. The file exists and the name used to import is correct.
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: libinference_engine.so: cannot open shared object file: No such file or directory

Solution:- Have to add the path for the file libinference_engine.so as /home/pi/openvino/inference_engine_vpu_arm/inference_engine/lib/armv7l/
in the file /etc/ld.so.conf.d/arm-linux-gnueabihf.conf of Raspbian Buster OS and run the command sudo ldconfig , now the cv2.cpython-35m-arm-linux-gnueabihf.so file can be imported as OpenCV to python site-packages.

In my installation the path to libinference_engine.so was slightly different, so I added this line:
~/openvino/inference_engine_vpu_arm/inference_engine/lib/raspbian_9/armv7l
to my ld.so.conf.d/arm-linux-gnueabihf.conf file. This solved the libinference_engine.so import error, but now raises a different import error:
libopencv_ml.so.4.0: cannot open shared object file
So, in the same spirit, I tried adding another line to the .conf file:
~/openvino/inference_engine_vpu_arm/opencv/lib
and ran sudo ldconfig once more. Now I'm back to having the original libinference_engine.so error as before :( Any ideas as to what I'm missing?
For context, I'm running raspbian buster on a RPi 4B 4GB, and I installed python 3.5.2 from a tar.gz download. My cv2.so is a symbolic link in the venv/lib/python3.5/site-packages pointing to ~/openvino/inference_engine_vpu_arm/inference_engine/python/python3.5/cv2.cpython-35m-arm-linux-gnueabihf.so
