Could not build wheels for opencv-python which use PEP 517 and cannot be installed directly

The error message "Could not build wheels for opencv-python which use PEP 517 and cannot be installed directly" usually means that there is a problem with the installation of the opencv-python package. This can happen when you are trying to install the package using pip.

One solution is to try installing the package using conda instead of pip. You can create a new conda environment and install opencv-python in that environment using the following commands:

conda create --name myenv
conda activate myenv
conda install -c conda-forge opencv

This will create a new environment called "myenv" and activate it, and then install opencv-python in that environment.

If you still want to use pip to install opencv-python, you can try upgrading pip to the latest version using the following command:

python -m pip install --upgrade pip

Then, you can try installing opencv-python again using pip:

pip install opencv-python

If this still doesn't work, you can try installing the dependencies for opencv-python manually before installing opencv-python itself. The dependencies are numpy and setuptools. You can install them using the following commands:

pip install numpy
pip install setuptools

Once you have installed these dependencies, you can try installing opencv-python again using pip:

pip install opencv-python
