I bet the caller is in the superclass _BaseHMM, like in the following made-
up example:

>>> class Base:
...     def __init__(self, x):
...         self._init(x)
...     def _init(self, x): print("do something with", x)
... 
>>> class Derived(Base):
...     def _init(self, x):
...         super()._init(x)
...         print("do something else with", x)
... 
>>> Derived(42)
do something with 42
do something else with 42
