cv2 not work after install mediapipe library

Question

I want to make handtracker program using python but the tutorial tell me to install mediapipe library, then I installed it. Before that it's okay using cv2 to stream my camera, but after installing mediapipe, the cv2 doesn't work here the message :

>>>import cv2
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import cv2
  File "C:\Users\windows\AppData\Local\Programs\Python\Python39\lib\site-packages\cv2\__init__.py", line 181, in <module>
    bootstrap()

    cv.gapi.wip.GStreamerPipeline = cv.gapi_wip_gst_GStreamerPipeline
AttributeError: partially initialized module 'cv2' has no attribute 'gapi_wip_gst_GStreamerPipeline' (most likely due to a circular import) ```

I tried to install opencv again but always get this message :

Requirement already satisfied: numpy>=1.19.3 in c:\users\windows\appdata\local\programs\python\python39\lib\site-packages (from opencv-python) (1.21.1)

but the problem still there. How do I fix it?

Edited : this is my pip list

Ensure you have only one version of OpenCV installed in your system/environment – Amphibology

perhaps mediapipe installed a conflicting package of OpenCV and now you've got multiple? probably. please list all the installed packages using pip. use pip list and find everything relating to opencv in that list. edit your question and add the information. if you see multiple opencv packages, uninstall all of them (using pip), then try reinstalling mediapipe. – Wedding

@ChristophRackwitz There is opencv-contrib-python and opencv-python in there, I'll try it – Vitreous

I found the problem, when I installed mediapipe there is opencv-contrib-python, make the opencv-python twice – Vitreous

Answer 1

I have the same situation like above you can try it:

pip install "opencv-python-headless<4.3"

This command has successfully resolved this situation

Answer 2

In any version(ex: 4.6.0.66), when you install any 2 of 3 packages: opencv-contrib-python, opencv-python-headless, opencv-python, make sure they have the same version. I also got the same error, I found out their versions are different. Then a synchronous update solved the problem.

installing those concurrently is a bad idea. only install one of them. they all contain the base modules (minus highgui, if headless). – Wedding

yeah, you do not understand what I mean. I mean with one or two of those libraries (you can install according to your needs). But make sure they are the same version. As question problem above, he/she didn't install opencv-contrib-python, opencv-python same version so gave error, don't know if there is another error but I also had this problem and solved it's like that. – Warbler

I do understand and am puzzled why you mistake that. it's still a bad idea to install those concurrently. that frequently leads to issues. – Wedding

Answer 3

I have similar problem, and I only have opencv-python installed. The problem is solved by installing opencv-python-headless.

---

My problem is more complicate than that. Actually the opencv-python is already installed in "root", but when I login as another user (dev), I get the problem as OP. I can install opencv-python-headless or opencv-contrib-python manually, then the system will work. But if I install them in "root", I sill have the same problem.

So the final solution I use is to reinstall opencv-python in my user environment (dev):

pip3 install --upgrade --force-reinstall opencv-python

Answer 4

I fix such a problem using the following commands.

pip uninstall opencv-contrib-python

pip install opencv-contrib-python

Answer 5

the following solution

pip install "opencv-python-headless<4.3"

fixed the error below when building OpenCV from source!

import cv2 Traceback (most recent call last): File "", line 1, in File "C:\ProgramData\Anaconda3\lib\site-packages\cv2_init_.py", line 181, in bootstrap() File "C:\ProgramData\Anaconda3\lib\site-packages\cv2_init_.py", line 153, in bootstrap native_module = importlib.import_module("cv2") File "C:\ProgramData\Anaconda3\lib\importlib_init_.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) ImportError: DLL load failed while importing cv2: The specified module could not be found.
