Import cv2 doesn't work for Python 3 after successfully installing OpenCV 4.6.0 and Ubuntu 22.04.1

Python

I am using Ubuntu 22.04 and anacondna3. The python version in virtual environment is 3.10. Both Cmake, make -j6 and make install did not throw any errors. I am getting no module “cv2” error. Please help

My CMake command is below.
CMakeCache.txt,
CMakeVars.txt

cmake \
-D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D WITH_QT=OFF \
-D WITH_CUDA=ON \
-D WITH_CUDNN=ON \

-D OPENCV_EXTRA_MODULES_PATH=/home/suresh/Downloads/opencv_contrib-4.6.0/modules \

-D INSTALL_PYTHON_EXAMPLES=ON \ 
-D OPENCV_GENERATE_PKGCONFIG=ON \
..

The pkg-config shows opencv4 version correctly

(cv46) ➜  build pkg-config --modversion opencv4
4.6.0

When I try the below python command, I am getting No module named “cv2” error.

(cv46) ➜  build python3 -c "import cv2; print(cv2.__version__)"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'cv2'

Do check cv2 folder is available in /usr/local/lib/python3.10/dist-packages/cv2.

If the cv2 folder is not available then it displays so.

Also, check after the CMake command you get this:

Python 3:
