I had the same issue and found this post usefull, specially the comment by merv.
Basically, there seems to be some incompatibilities between the configuration needed for the default packages of anaconda and the one for the opencv package.
In order to solve the problem you need to created a new enviroment for conda. This enviroment will contain the opencv package with the proper configuration without afecting other packages.
conda create --name env_opencv -c conda-forge opencv
This will create the "env" and install opencv in it with the configuration required by the package.
Then activate the enviroment.
conda activate env_opencv
More info about the enviroments on conda can be found here

I'd like to utilize my Movidius Neural Compute Stick 1 (NCS1) to learn deep learning.
However, when I run a sample code, the following import error occurs:
python3 emotion.py -i sample.jpg -o result.jpg
Traceback (most recent call last):
File "emotion.py", line 1, in <module>
import cv2
File "/opt/intel/openvino/python/python3/cv2/__init__.py", line 129, in <module>

ImportError: /opt/intel/openvino/opencv/lib/libopencv_dnn.so.4.5:
undefined symbol: _ZN15InferenceEngine5TBlobIhSt9enable_ifILb1EvEED1Ev
I'm using a Raspberry Pi 3B.
The OS is Raspberry Pi OS 32-bit (Legacy) Buster because Bullseye doesn't support NCS1.
OpenVINO Version is l_openvino_toolkit_runtime_raspbian_p_2020.3.194.tgz,
which is the last version that supports NCS1.
Here's how to reproduce.
I installed Raspberry Pi OS 32-bit (Legacy) Buster onto the microSD.
After some simple initial settings, I typed these commands to install the OpenVINO toolkit:
sudo mkdir -p /opt/intel/openvino
mkdir ~/download
cd ~/download
wget https://storage.openvinotoolkit.org/repositories/openvino/packages/2020.3/l_openvino_toolkit_runtime_raspbian_p_2020.3.194.tgz
sudo tar -xf l_openvino_toolkit_runtime_raspbian_p_2020.3.194.tgz --strip 1 -C /opt/intel/openvino
echo "source /opt/intel/openvino/bin/setupvars.sh" >> ~/.bashrc
source /opt/intel/openvino/bin/setupvars.sh
sudo usermod -a -G users "$(whoami)"
sh /opt/intel/openvino/install_dependencies/install_NCS_udev_rules.sh
In order to set up the OpenCV environment, I typed:
sudo apt update
sudo apt install -y python3-pip
sudo apt install -y libopencv-dev
sudo apt install -y python3-numpy
pip3 install pillow
That's it.
Then, I downloaded necessary images and codes, and ran emotion.py.
The whole contents of emotion.py doesn't matter here because only the first line gives me the error.

Also, I tried to use berry-conda to do a similar thing with this answer.
But, it failed because the package libprotobuf is missing:
(After berry-conda installation)
pi#raspberrypi:/tmp $ which python
/home/pi/berryconda3/bin/python
pi#raspberrypi:/tmp $ which conda
/home/pi/berryconda3/bin/conda
pi#raspberrypi:/tmp $ python --version
Python 3.6.1
pi#raspberrypi:/tmp $ conda install -c defaults libprotobuf protobuf
Fetching package metadata .....
PackageNotFoundError: Package missing in current linux-armv7l channels:
- libprotobuf
This berry-conda installation completely changed my previous environment above.
I don't know if I should keep using berry-conda
or re-install Raspberry Pi OS 32-bit (Legacy) Buster again to do it from scratch.
Any suggestions would be greatly appreciated.
The error message is indicating that there is an issue with an undefined symbol in the libopencv_dnn.so.4.5 library, which suggests that there may be a compatibility issue between OpenVINO and the version of OpenCV installed on your system.
You could try reinstalling OpenVINO and making sure that it is properly configured with your system's version of OpenCV. You could also try updating or reinstalling OpenCV.

I am facing problem while getting opencv to work with python 3.7 in Conda on Ubuntu 20.04.
I get the following error when I try to import cv2 in python:
$ python

my Conda configuration looks something like this:

I installed opencv from the conda-forge channel using the following command:
$ conda install -c conda-forge opencv
I can see that opencv is installed on my system:
$ conda list opencv
# packages in environment at /home/swagat/anaconda3/envs/tf2py37:
#

libopencv 4.5.0 py37_2 conda-forge
opencv 4.5.0 py37_2 conda-forge

I also checked if gnutls is installed:
$ conda list gnutls
# packages in environment at /home/swagat/anaconda3/envs/tf2py37:
#
# Name Version Build Channel
gnutls 3.6.13 h79a8f9a_0 conda-forge
What else I can try to solve this problem? I am kind of stuck here. Any help will be appreciated. Thanks.
It seems that conda version of the opencv is broken.
My solution is:
remove your conda opencv and install the native one:
conda remove opencv
python -m pip install opencv-python # Execute this with your conda env activated
I am trying to install 32-bit packages on official alpine docker images but whenever I do apk add libcurl for example it install 64-bit version of libcurl whereas I want to install 32-bit package.
Any thoughts how to do the same on Alpine Linux 3.7?
Actually, only one file defines which packages take from alpine repos. It is /etc/apk/arch:
# cat /etc/apk/arch
x86_64
Its value shows which packages we should take from our alpine repos:
# cat /etc/apk/repositories
http://dl-cdn.alpinelinux.org/alpine/v3.7/main
http://dl-cdn.alpinelinux.org/alpine/v3.7/community
So, we can make a trick here. We can "switch" alpine to get x86 packages from the repos:
/ # echo "x86" > /etc/apk/arch
/ # apk add --no-cache libcurl
fetch http://dl-cdn.alpinelinux.org/alpine/v3.7/main/x86/APKINDEX.tar.gz

Since you're using Docker, why not use the 32-bit alpine image?
$ docker run --rm -it i386/alpine

Has anyone tried to install opencv for python3?. As stated here http://opencv.willowgarage.com/wiki/InstallGuide its support status is unknown. So I want to try it:
I have downloaded the sources for OpenCV-2.3.1. But cmake reports.
-- Python interpreter: /Library/Frameworks/Python.framework/Versions/3.2/bin/python3 -B (ver
3.2)
-- Python numpy: NO (Python wrappers will not be generated)
I do have numpy (version 1.6.0) installed in python3 but cmake does not find it. I am using Mac OSX 10.6 Any ideas?
Update
I just saw one more thing of the cmake output that might be helpful
-- Found PythonInterp: /Library/Frameworks/Python.framework/Versions/3.2/bin/python3 (found
version "3.2")
-- Found PythonLibs: /usr/lib/libpython2.6.dylib File "", line 1
from distutils.sysconfig import *; print get_python_lib()
^
SyntaxError: invalid syntax File "", line 1
import os; os.environ['DISTUTILS_USE_SDK']='1'; import numpy.distutils; print
numpy.distutils.misc_util.get_numpy_include_dirs()[0]
^
SyntaxError: invalid syntax File "", line 1
import sphinx; print sphinx.__version__
^ SyntaxError: invalid syntax
Notice that it found 3.2 but then libpython2.6 ??
Any ideas?
At the moment OpenCV supports Python 2.x only. OpenCV (including OpenCV 2.4) does not compiles with Python 3.x.
Python3 support is already in wishlist for future versions of OpenCV. But currently there are no activities in this direction and you are welcome to create and contribute a patch resolving the compatibility issues.
Use the pip application.
On ubuntu:
sudo apt install python3-pip
and so, on command line:
pip3 install --upgrade pip
pip3 install opencv-python
I got the thing to at least build and install. It can load the cv2 module just fine. Haven't tested too much though.
