It was cut and pasted from working code (which I pasted back to test).

Nope. self._all_states is a set. I am collecting all mentioned states

from the key. Another way to do it is:

self._all_states = set()

for key in probabilities:

self._all_states = set(key)

-- key is a order-tuple of states.
