Description
Hi,
I installed opencv-contrib-python 4.7.0.72 using pip for python 3.11.4 on Windows 10 x86-64
But when I run I get this exceptiom DLL load failed while importing cv2: The specified module could not be found.
Expected behaviour
I expect the module to import and not trow an error.
Actual behaviour
This exception gets trown
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python311\Lib\site-packages\cv2\__init__.py", line 181, in <module>
bootstrap()
File "C:\Python311\Lib\site-packages\cv2\__init__.py", line 153, in bootstrap
native_module = importlib.import_module("cv2")
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "C:\Python311\Lib\importlib\__init__.py", line 126, in import_module
return _bootstrap._gcd_import(name[level:], package, level)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Steps to reproduce
- example code
import cv2 - operating system
Windows 10, i7-12700H with Intel Iris Xe Graphics and a NVIDIA RTX A1000 - architecture (e.g. x86)
x86-64 - opencv-python version
opencv-contrib-python-4.7.0.72
Issue submission checklist
- This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
- I have read the README of this repository and understand that this repository provides only an automated build toolchain for OpenCV Python packages (there is no actual OpenCV code here)
- The issue is related to the build scripts in this repository, to the pre-built binaries or is a feature request (such as "please enable this additional dependency")
- I'm using the latest version of
opencv-python

Research direction
Start by reproducing import cv2 with Python 3.11.4, Windows 10 x86-64, and opencv-contrib-python 4.7.0.72. Read the bootstrap path in cv2/__init__.py and investigate the reported DLL-loading failure in that environment. Done means the package imports successfully without the exception.
