There's probably a more elegant solution appending paths programmatically but I couldn't get that to work so ended up having to change most 'from src.x.y.z' to 'from .src.x.y.z' to get this to load in ComfyUI. The files that were nested within src then needed to have their 'from src.x.y.z' to be relative to their location with '.z' or '..z'
