warning: requirement 'opencv_contrib_python-3.4.11.45-cp39-cp39-win_amd64.wh' not found in the package index. It means that the required package 'opencv_contrib_python' with version '3.4.11.45' for Python 3.9 is not available for download from the standard package repositories.
To resolve this issue, you can try the following steps:
1. Check the spelling and version number of the required package. Make sure it is correct and matches the version you need.
2. Make sure you have the correct package manager installed. For Python, 'pip' is commonly used. You can verify its installation by running the command 'pip --version' in the command prompt or terminal.
3. Update the package index by running the command 'pip install --upgrade pip' to ensure you have the latest version of pip.
4. Confirm that you have internet connectivity and can access the package repositories.
5. If the required package is not available in the standard repositories, you may need to check alternative package repositories, such as Anaconda, to see if the package is available there.
6. If the package is not available in any repositories, you might need to find alternative solutions or seek help from forums or the developer community for assistance.
Remember to consider compatibility issues between the package versions, Python versions, and your operating system. It's also worth checking if there is any dependency conflict with other installed packages.
