I am trying to install opencv package on Raspberry Pi (Stratodesk OS). the best shot I got so far is through: https://www.piwheels.hostedpi.com/simple

However, after installing 

pip install opencv-contrib-python --extra-index-url https://www.piwheels.hostedpi.com/simple

when importing the cv2 in python I get import error message related to libhdf5_serial.so.100:

root@PNAR55:~# python3
Python 3.5.2 (default, Nov 12 2018, 13:43:14)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.

import cv2
Traceback (most recent call last):
File "", line 1, in
File "/usr/local/lib/python3.5/dist-packages/cv2/init.py", line 3, in
from .cv2 import *
ImportError: libhdf5_serial.so.100: cannot open shared object file: No such file or directory

besides, I tried to install opencv-python but without success

pip install opencv-python --extra-index-url https://www.piwheels.hostedpi.com/simple

when importing cv2, I am getting a different ImportError message related to liblapack.so.3

import cv2
Traceback (most recent call last): File "", line 1, in File "/usr/local/lib/python3.5/dist-packages/cv2/init.py", line 3, in from .cv2 import * ImportError: liblapack.so.3: cannot open shared object file: No such file or directory

for your information, Stratodesk OS is quite different that Raspbian. I do not have git, cmake, apt-get commands.

if there is a way to overcome the error messages I am getting

Im stuck here too. I am trying to remove the new libhdf5_serial.so I think its 103 and install the old one libhdf5_serial.so.100 I think that should fix the issue - MNM

This problem is due to an incompatibility between your board and the OpenCV version. If you installed it via pip try pip uninstall opencv-python or pip3 uninstall opencv-python (depending of the python version you need (pip for python2 and pip for python3). After uninstaling is complete, try to search for an older version of opencv and install via pip3 install opencv-python==3.4.6.27 (this is the version that worked for me. I'm almost sure you'll need another one). Also, check this link, and this one!
