In case when proposal_distribution is 'Prior', proposal_sd was never
set, that would result in the following error:
Warning, unable to save state.
Error message:
Traceback (most recent call last):
File "/usr/local/lib/python2.7/dist-packages/pymc/Model.py", line 599, in save_state
self.db.savestate(self.get_state())
File "/usr/local/lib/python2.7/dist-packages/pymc/MCMC.py", line 344, in get_state
state['step_methods'][sm._id] = sm.current_state().copy()
File "/usr/local/lib/python2.7/dist-packages/pymc/StepMethods.py", line 293, in current_state
state[s] = getattr(self, s)
AttributeError: 'Metropolis' object has no attribute 'proposal_sd'
Now set proposal_sd = None by default.
