Aging a person. Is there a ready-made library (neural network) for working with photos?

Question

Neural networks

The task is this, you need to write a neural network, train it so that it can find differences in two photos and apply changes to the 3rd photo. For example, for training, there are two photographs of a young and an old person. The neural network should age the person in the 3rd photo.
Are there any ready-made libraries for writing such a neural network under node.js or another PL? In which direction to dig?
