Answer 1

I got openCV installed smoothly in my mac by:

$ brew install opencv
$ brew link --overwrite --dry-run opencv // to force linking
$ pip3 install opencv-contrib-python

I got it at windows 10 using:

c:\> pip3 install opencv-python
c:\> pip3 install opencv-contrib-python

Then I got it tested by

$ python3
Python 3.7.3 (default, Mar 27 2019, 09:23:15) 
[Clang 10.0.1 (clang-1001.0.46.3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> cv2.__version__
'4.1.0'
>>> exit()

Answer 2

I had a similar problem:

module cv2 has no attribute "cv2.TrackerCSRT_create"

My Python version is 3.8.0 under Windows 10. The problem was the opencv version installation.

So I fixed this way (cmd prompt with administrator privileges):

1. Uninstalled opencv-python: pip uninstall opencv-python
2. Installed only opencv-contrib-python: pip install opencv-contrib-python

Anyway you can read the following guide:

Answer 3

RESTART YOUR IDE

I tried all of the different things but nothing seems to be working then I just restarted my IDE and it worked like charm.

Still, if it does not work then try restarting your system.

FYI, I am working on the following versions

opencv-contrib-python==4.4.0.46
opencv-python==4.1.2.30

Answer 4

Check your OpenCV version

import cv2
cv2.__version__

If your are running Python v3.x and OpenCV v4 and above:

pip install opencv-contrib-python

Try running your program again. This should now work.

Answer 5

You might be running Python3 and therefore you are supposed to use pip3 to install the opencv-contrib package :

pip3 install opencv-contrib-python

This worked for me.

Answer 6

For me changing createLBPHFaceRecognizer() to

recognizer = cv2.face.LBPHFaceRecognizer_create()

fixed the problem
