Performance optimization of python machine learning

Hi freelancers!

I have a python image enhance project where the model takes too long to enhance the image. I need a specialist in the field to make the model run fast. Right now it takes around 15 seconds pr. image to enhance. I will need the best possible speed optimization.

Python model is using 4 models.
1. scale face detectors
2. facial points recognition
3. face enhancement model
4. super resolution model

The two heavy models are face and super resolution.

I need an expert.
