安装 mediapipe 库后 cv2 不工作

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

C:\Users\windows>pip list

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

Reference: https://github.com/Rudrabha/Wav2Lip/issues/387

Answer 2

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

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!
