   Thanks for reporting this.
   
   This works as designed / intended. Base compute API declares those arguments to be of a type of NodeImage and NodeSize.
   
   If any of the drivers supports string notation, that's because they don't comply with the base compute API.
   
   In the past, we didn't have a good automated way to enforce compliance with the base API so some things like that have slipped through, but going forward, some of that will be easier with the MyPy support.
   
   In short, in scenarios like that, you need to instantiate ``NodeImage`` and ``NodeSize`` classes yourself manually (although some drivers may offer convenience extension methods for that).
