ImportError: OpenCV loader: missing configuration file

[arielkantorovich]

Environment

WSL2 - Ubuntu 22.04
miniconda env with python 3.10 version
Opencv version 4.10

Steps to reproduce

I try to compile Opencv with CUDA on my wsl2 machine. here is my Cmake file list:
cmake
-D CMAKE_BUILD_TYPE=RELEASE
-D CMAKE_INSTALL_PREFIX=/usr/local
-D WITH_CUDA=ON
-D WITH_CUDNN=ON
-D WITH_CUBLAS=ON
-D WITH_TBB=ON
-D OPENCV_DNN_CUDA=ON
-D OPENCV_ENABLE_NONFREE=ON
-D WITH_GSTREAMER=ON
-D WITH_V4L=ON
-D WITH_LIBV4L=ON
-D CUDA_ARCH_BIN=8.6
-D OPENCV_EXTRA_MODULES_PATH=$HOME/opencv_contrib/modules
-D BUILD_EXAMPLES=OFF
-D HAVE_opencv_python3=ON
..

Succeed to compile and finish.
Succeed to install on conda env using pip3 install opencv/build/python_loader

Issue

Try import cv2 from python and get the following error:

import cv2 Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/arielka/opencv/build/python_loader/cv2/__init__.py", line 181, in <module> bootstrap() File "/home/arielka/opencv/build/python_loader/cv2/__init__.py", line 112, in bootstrap load_first_config([ File "/home/arielka/opencv/build/python_loader/cv2/__init__.py", line 109, in load_first_config raise ImportError('OpenCV loader: missing configuration file: {}. Check OpenCV installation.'.format(fnames)) ImportError: OpenCV loader: missing configuration file: ['config-3.10.py', 'config-3.py']. Check OpenCV installation.

Should be fixed in #1000

Thank you I am not really understand I need change setup.py file in python loader or uninstall and recompile everything once again?
Here is my setup.py
`import os
import setuptools

SCRIPT_DIR = os.path.dirname(os.path.abspath(file))

stub_files.extend(
map(lambda p: os.path.join(module_path, p),
filter(lambda f: f.endswith(".pyi"), files))
)
return stub_files

def main():
os.chdir(SCRIPT_DIR)

package_name = 'opencv'
package_version = os.environ.get('OPENCV_VERSION', '4.10.0')  # TODO

long_description = 'Open Source Computer Vision Library Python bindings'  # TODO

py_typed_path = os.path.join(root_module_path, "py.typed")
typing_stub_files = []

    typing_stub_files = collect_module_typing_stub_files(root_module_path)
    if len(typing_stub_files) > 0:
        typing_stub_files.append(py_typed_path)
