Tony607/Keras_age_gender — reverse-engineered prompt

Build me a simple Python app that uses my webcam to detect faces in real time and show an estimated age and gender on the video feed. I want it to feel like a quick demo I can just run locally, with a script that opens the camera, draws boxes around faces, and overlays the predictions clearly on screen.

Please use the existing pretrained model setup so the weights download automatically the first time and get saved in a local pretrained_models folder. Keep it easy to start with a requirements file and one main run command. If there are any small compatibility issues with newer environments, fix them so it actually works without a lot of manual tinkering.

I do not need a big product or web app, just a clean real time desktop demo from the webcam. If anything is unclear, look up the current docs online and make the smallest practical updates needed while keeping the original idea intact.
