It is OpenCV you can install it by pip install opencv
but I recommend installing it from source, as the python binary may not have video processing module in it. http://opencv.org/
after run suod apt-get install python-opencv it passed, but new trouble come:
envy@ub1404:~/os_pri/github/video_to_sequence$ python download_videos.py
Traceback (most recent call last):

would you like show me the result of 'pip list'?
failed on window
C:>pip install opencv-python Collecting opencv Could not find a version that satisfies the ) No matching distribution found for opencv
check the the version of your python, if you are using python 3 sometimes you have to call pip3
pip3 install opencv-python
make sure you are using python3 and not python 2 in run
"pip3.6 install opencv" gives back error message:
No matching distribution found for opencv
@prabinzz you have to give pip a version, like this: pip install opencv-python=={version}
for python3.5, You can do by using this command => sudo pip3 install opencv-python
ensure you have installed numpy and scipy then "pip install opencv-python" or"pip install opencv-python==version" for u can use source of ustc "pip install opencv-python -i http://pypi.mirrors.ustc.edu.cn/simple"
In web2py ,opencv version is 2.But in my local machine opencv version 3.2.ORB_create() is supported in my local machine.But in web2py ORB_create() is not supported . Can you give me any solution?Thanks in advance.
I have window10 and Python3.6. I did pip install panda pip install opencv-python
worked!
for ubuntu 16.04 pip3 install opencv-python //does not work pip install opencv-python //works for me
if you use ananconda , you can install opencv by conda: conda install opencv
If you have multiple versions of python on linux :
python2 -m pip install opencv-python # python2.x python3.5 -m pip install opencv-python #python3.5 python3.6 -m pip install opencv-python #python3.6
add --user in the end if you have permission issues.
you might also install pip install opencv_contrib-python as some module are missing in opencv
If you've been like me starting to install everything after June 27th 2018, make sure you are not using Python 3.7. Otherwise you'll get the error since this version is not supported yet by OpenCV
Collecting opencv-python
Could not find a version that satisfies the requirement opencv-python (from versions: )
No matching distribution found for opencv-python
@adriendomoison thanks a lot for this information! I was able to make opencv-python work with python2.7 - just sticking with that for now.
BTW is there a Python3 version you know which supports opencv-python?
