AttributeError: partially initialized module 'cv2' has no attribute 'gapi_wip_gst_GStreamerPipeline' (most likely due to a circular import)

Question

This happened out of the blue, I was able to import cv2 but now I get 'AttributeError: partially initialized module 'cv2' has no attribute 'gapi_wip_gst_GStreamerPipeline' (most likely due to a circular import)' error when I import it. The things I tried:

1-uninstalling and installing opencv. 2-In cmd, I typed "pip list" and opencv-python package is listed. I ran "python" command and tried importing cv2 but I get the same error. Please help.

Does this answer your question? AttributeError: partially initialized module 'cv2' has no attribute 'CascadeClassifier' (most likely due to a circular import) – Clupeoid

I've already tried that solution does not work. – Relentless

and how's this? #72546279 – Clupeoid

@ÖmerFarukAydın Create a new virtual environment, install OpenCV and try – Epanorthosis

I changed my anaconda environment but it caused some other bugs. I just uninstall anaconda and installed it. It works now – Relentless

Answer 1

I also had the same problem with opencv-python-4.6.0.66

I solved this error by just downgrading opencv. you can follow this command.

pip install opencv-python==4.5.5.64

Hope this will help you.

for me (in a container) pip install opencv-python-headless==4.5.5.64 worked. The newest version, albeit also headless, did not work, it showed a different error. – Lifework

If your issue is indeed that the currently installed package is out of date, pip install opencv-python --upgrade will get you the latest one. – Oratorical

it worked for me and the git-sym package! thank you – Caret

what if i need opencv-python>=4.6? – Desiraedesire

Answer 2

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

and then

pip3 install opencv-contrib-python==4.5.5.62

thanks sir! this helped me out today with a scary issue – Forme

Answer 3

Same problem here when I had:

> pip list
opencv-contrib-python 4.6.0.66
opencv-python         4.5.4.58

Upgraded opencv-python to 4.6.0.66 (> pip install opencv-python==4.6.0.66) and that fixed it.

Thanks. Just in case, to get the list pip list | grep opencv – Kaufman

Answer 4

Updating the package https://pypi.org/project/opencv-python/ to version 4.6.0.66 worked for me

Answer 5

I also had the same problem. I tried some of the solutions. Also, I had "ImportError: cannot import name '_registerMatType' from 'cv2.cv2' (C:\Users\user_name\anaconda3\envs\tf_od\lib\site-packages\cv2\cv2.cp39-win_amd64.pyd)" this error.

And I resolve the issue by checking OpenCV libraries installed on my Anaconda Environment by

pip list

opencv-contrib-python         4.6.0.66
opencv-python                 4.6.0.66
opencv-python-headless        4.5.2.52

I think everyone may have a different combination of these versions and others. So you should check and uninstall all OpenCV libs. And then install opencv-python.

In my case:

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

pip install opencv-python

Answer 6

Upgrading opencv solved the issue for me: !pip install opencv-python==4.6.0.66

Answer 7

As of February 2023, had the same error with opencv-python version 3.4.4.19. Upgrading to version 3.4.5.20 solved the problem.

Answer 9

It might to be the version of "opencv-contrib-python" and "opencv-python" should be consistent.
