ModuleNotFoundError: No module named '_dlib_pybind11'

This error message indicates that Python is unable to find the '_dlib_pybind11' module, which is likely required by the program or script you are running.

To resolve this issue, you can try the following steps:

1. Ensure that the module is installed on your system. You can do this by running the command `pip show _dlib_pybind11` in your terminal or command prompt. If the module is not found, you can install it using `pip install _dlib_pybind11`.

2. If the module is still not found, you can try uninstalling and reinstalling it using `pip uninstall _dlib_pybind11` followed by `pip install _dlib_pybind11`.

3. If neither of the above steps works, you may need to check your Python environment to ensure that it is properly configured and that all necessary dependencies are installed. This may involve checking your PATH variables, updating your Python version, or reinstalling Python altogether.
