I am unable to use pip install directly with the Python 3.12.8 interpreter that comes with GIMP 3.0.0 RC2. As a workaround, I use my system Python 3.12.8 to install the required packages (e.g., numpy) using pip. After installation, I manually copy the entire site-packages directory from my system Python environment to the corresponding site-packages directory in GIMP’s Python environment.

However, I am not sure if there are any files or dependencies that I might be missing when copying over the site-packages folder manually. If there’s a better or more reliable way to do this, I’d love to know.
