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
<__main__.Derived object at 0x7f8e6b3e9b70>
