How to test model that has a sub model in it?

So I have this repo,

link

GitHub - eugenelet/Meta-rPPG: Implementation of "Meta-rPPG: Remote Heart Rate Estimation Using a Transductive Meta-Learner"

that only gives me a sample of their dataset as pth but not a pre-trained model… I already analyzed what the input shape is and was able to recreate it with another dataset, but now I’m kinda stuck on how to test this model… any idea how to do it? any suggestions are welcomed!
