How to save and load trace

You do need to reinitialized the model, meaning that you should run the same model code, excluding the pm.sample(...) line.

For what it is worth, I have found this to be a good pattern in pymc3 - to separate the modelling step from the sampling step. I even will often define a model in a function, and do things like

def my_model():
    with pm.Model() as model:
        x = pm.Normal('x')
        ...
    return model

with my_model():
    other stuff
