Best Practices for Priors and Flattened 3D Matrices

It shouldn’t make a difference for the sampler. Generally this form is easier to work with, it involves less manually relabeling things whenever you want to make a change to the model:

@mmn

with pm.Model() as model:
    # Priors for unknown model parameters
    k = pm.Uniform("k", 1000, 50000, shape=(10,))
    k_vals = pm.Deterministic("k_vals", k)
