DLL load failed while importing cv2

[Mm_M]

I have installed python 3.11.5 on my windows machine and I have downloaded opencv using the command: pip3 install opencv-python

I have followed this tutorial to copy the python 3.10 cv2 file of OpenCV (as there is no 3.11 python file) and opencv_world480.dll file in python 3.11.5 site-packages.

But when I try to import cv2 in python idle, it appears the following error: Traceback (most recent call last): File "<pyshell#1>", line 1, in <module> import cv2 ImportError: DLL load failed while importing cv2: %1 no es una aplicación Win32 válida.

I have read this post and I have tried using the “unofficial site” (pip install opencv_python-3.2.0‑cp36‑cp36m‑win_amd64.whl) but it still does not work.

I have also tried with: pip install opencv-contrib-python

But still having the same result.

I’m not sure if I am adding cv2 to python site-packages as it should be as I have in the end:

I may be wrong but it seems like you are mixing up two different installation methods.

• If you pip install you shouldn’t need to copy any dll’s accross.

• If you are building from scratch then don’t pip install (pip uninstall any existing OpenCV installation first ) and read
  ImportError: DLL load failed while importing cv2: The specified module could not be found to see if it helps.
