AttributeError: module 'cv2' has no attribute 'VideoCapture'
Question:
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:UsersHoang Cao ChuyenDocumentspymlcv11.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:UsersHoang Cao ChuyenDocumentspymlcv11.py"]
Answers:
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:
- remove OpenCV
- reinstall using command
pip install opencv-contrib-python
OR
try reinstalling ffmpeg as it might be one of the issue
pip install ffmpeg-python
After asking my friend,i had the solution.It is very easy because i saved this file in Documents path in user which my private name Hoang Cao Chuyen without ‘_’.I changed into another path,and it was OK.
Add these two lines:
from cv2 import VideoCapture
from cv2 import waitKey
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
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:UsersuserAppDataLocalProgramsPythonPython39Libcv2
Package directory: C:UsersuserAppDataLocalProgramsPythonPython39Libcv2cv2
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:UsersuserAppDataLocalProgramsPythonPython39Libcv2_
That is the solution that is currently (and hopefully in the future as well) working for me).
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 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
