Description

One of the biggest pain of PyMC GP is that it holds reference to live variables from the graph in the class instance (self.sigma or whatever), so we can't operate on the PyMC model as a graph directly (say pm.observe, pm.do, pm.marginalize ...).

Does this sort of problem persist in this design?

Research direction

The issue names no file or test. Start by tracing the GP class and how it handles live PyMC or PyTensor variables, then check behavior with pm.observe, pm.do, and pm.marginalize. Done means documenting whether the design preserves graph operations and defining a reproducible case and agreed change if it does not.
