AttributeError: module 'cv2' has no attribute 'VideoCapture'

I had some problems with Opencv in Python.

This attribute problem also happens with imread

I tried to uninstall and reinstall with contrib-Opencv,but it did not work.

About 2 months ago, my opencv file still worked well, but I don't know why it doesn't work now.

In the next reinstallations,this command always sastifies but no good results

import cv2
cap = cv2.VideoCapture(0)
...
cap.release()

My error command:

Traceback (most recent call last):
  File "C:\Users\Hoang Cao Chuyen\Documents\pyml\cv11.py", line 4, in <module>
    cap = cv2.VideoCapture(0)
AttributeError: module 'cv2' has no attribute 'VideoCapture'
[Finished in 0.2s with exit code 1]
[shell_cmd: python -u "C:\Users\Hoang Cao Chuyen\Documents\pyml\cv11.py"]

Same problem occurs with me. And I fix it completely, by reading this resource: https://pypi.org/project/opencv-python/#installation-and-usage,

In FAQ section it is mentioned, that if you are on Windows 10 ProN, then install Windows Media Pack Features and Visual C++ redistributable 2015 is must.

I have faced issue in Python 3.9.2 with opencv-python-4.7.0.72.

Remove all opencv related libraries then installed it again. If need remove virtual environment then create virtual environment and install opencv.

pip uninstall opencv-python
pip uninstall opencv-python-headless
pip uninstall opencv-contrib-python

install

pip install opencv-python

The best way to solve all the problems of OPENCV-PYTHON is by uninstalling it and reinstalling it.

Even I faced the same problem.

I fixed it by:

python -m pip uninstall Opencv-python

Then I reinstalled it by using a lower version. But unfortunately, I did not know the versions of opencv; So by using a small trick you can get it by running:

python -m pip install opencv-python==

and you will get an error similar to this:

.45, 3.4.13.47, 3.4.15.55, 3.4.16.57, 3.4.16.59, 3.4.17.61, 3.4.17.63, 4.3.0.38, 4.4.0.40, 4.4.0.42, 4.4.0.44, 4.4.0.46, 4.5.1.48, 4.5.3.56, 4.5.4.58, 4.5.
4.60, 4.5.5.62, 4.5.5.64)
ERROR: No matching distribution found for opencv-python==

Here you can see all the versions of opencv-python; choose any one (but not the latest as the error occurs due the latest version of opencv-python. install it by using:

pip install opencv-python==3.4.17.61 (You can choose your version, but this version solved the issue for me)

then enjoy your coding....

Even AUTO-COMPLETE error in opencv-python gets solved.

I had the same problem and was searching for ages. Finally I found a way that is (at least currently) working for me.

When installing opencv there will be a folder 'cv2' which again includes the package 'cv2'.

Installation directory: C:\Users\user\AppData\Local\Programs\Python\Python39\Lib\cv2 Package directory: C:\Users\user\AppData\Local\Programs\Python\Python39\Lib\cv2\cv2

Directory after installation


Probably this leads to confusing for python (maybe some circular import or so). Therefore I just renamed the installation directory to something else, e.g. C:\Users\user\AppData\Local\Programs\Python\Python39\Lib\cv2_

Directory after renaming

That is the solution that is currently (and hopefully in the future as well) working for me).

The problem is that your file is called cv2.py so it imports itself and an error occurs, this can be understood from this line.

Most likely due to a circular import

Which translates as:

Most likely due to circular import

To fix the problem, rename your file

Add these two lines:

from cv2 import VideoCapture
from cv2 import waitKey

One of the issue I noticed is that you used cv11 as the main.py name.

It is very easy for PyCharm to get confused if you have a file saved as cv2.py. Please check if you have any other similar files with the name cv2.

Else, try to do this:

  1. remove OpenCV
  2. reinstall using command pip install opencv-contrib-python

OR

try reinstalling ffmpeg as it might be one of the issue

pip install ffmpeg-python
