Nested Submodels

Questions
1

Does PyMC have anything like Turing.jl’s @submodel macro? I want to compose several Python models together, so that I can keep different parts of my model separate while I work on them and make my code more readable. Thanks!

You can create submodels inside models:

with pm.Model() as m:
  with pm.Model() as sub_m1:
    ...
  with pm.Model() as sub_m2:
    ...

All the variables in sub_m* will be added to m. Does that achieve what you wanted?

Partly, but is there a way to define the submodels separately, then call them from inside the main model? (Like functions?)

You could implement an extend_model function, which would update the parent model attributes with the new variables.

These are the things you need to populate:

You can add new items to treedicts (just a subclass of dict) and append new values to treelists (just a subclass of lists)
