Your screenshot shows you doing a pip install from the python terminal which is wrong   Do that outside the python terminal   Also the package I believe you want is    pip install opencv-python   Since you re running on Windows  I might look at the official install manual  https   breakthrough github io Installing-OpenCV  opencv2 is ONLY compatible with Python3 if you do so by compiling the source code   See the section under opencv supported python versions  https   pypi org project opencv-python

well  there was 2 issues  1 instead of pip  pip3 should be used  2 its better to use virtual env  because i have had multiple python version installed
