How to use a pre-trained model in ray serve?

I am new to ray serve, and I am just getting started with ray serve. I have a project where I have to use a pre trained model with ray serve using python and that pre trained model is Microsoft Florence vision model which will do both text and image-based task. So, I want to know that how can I use ms florence in ray serve, as I tried to use it there were so many errors and if it was running properly then it was not getting deployed on ray serve or not giving any output. I want to know that how to use this ray serve and if there is any youtube channel or any website which provides solution to the problems instantly as ChatGPT is not able to help that much with ray serve. How can I get the main output and how to deploy it. I really want to know ray serve properly.
