I am trying to record video in a python program. I can see the video on my screen but when I check the video attribute “video.isOpened()” I get an error that says videoCapture has no attribute ‘isOpened’. I am using opencv-python (Version 4.5.5.62) and am using opencv-contrib-python-4.5.5.64. Can anyone point me in the right direction toward solving this problem? I have tried Google but to no avail. Thanks. ---

please show exact code snippet (it’s probably something silly) also: > [@johnWorker](#): > > I am using opencv-python (Version 4.5.5.62) and am using opencv-contrib-python-4.5.5.64. please do NOT install _both_, only the latter ! ---

I removed opencv-python and that seems to have fixed the issue. Would it be too difficult to explain why only one of those modules should be installed? I am quite happy to look at documentation and have done so but I did not see any mention of having one or the other installed. The whole pip install opencv-python and importing the module as cv2 is confusing. Is there any source that can give clarity to this? Thanks. ---

> [@johnWorker](#): > > Would it be too difficult to explain why only one of those modules should be installed? both are called cv2, and python can only load one of them at a time. (opencv-contrib-python is a “superset” of opencv-python) ---

Wow, how unfortunate. Thanks for the help. ---

As berak wrote You cannot install both : [### Installation and Usage 1. If you have previous/other manually installed (= not installed via `pip` ) version of OpenCV installed (e.g. cv2 module in the root of Python’s site-packages), remove it before installation to avoid conflicts.]([opencv-contrib-python · PyPI](https://pypi.org/project/opencv-contrib-python/))
