Poutine (Effect handlers)

Beneath the built-in inference algorithms, Pyro has a library of composable effect handlers for creating new inference algorithms and working with probabilistic programs. Pyro's inference algorithms are all built by applying these handlers to stochastic functions.

Handlers

.. automodule:: pyro.poutine.handlers


.. autofunction:: pyro.poutine.block


.. autofunction:: pyro.poutine.broadcast


.. autofunction:: pyro.poutine.condition


.. autofunction:: pyro.poutine.do


.. autofunction:: pyro.poutine.enum


.. autofunction:: pyro.poutine.escape


.. autofunction:: pyro.poutine.infer_config


.. autofunction:: pyro.poutine.lift


.. autofunction:: pyro.poutine.markov


.. autofunction:: pyro.poutine.mask


.. autofunction:: pyro.poutine.queue


.. autofunction:: pyro.poutine.replay


.. autofunction:: pyro.poutine.scale


.. autofunction:: pyro.poutine.trace


.. autofunction:: pyro.infer.enum.config_enumerate

Messengers

Messenger objects contain the implementations of the effects exposed by handlers. Advanced users may modify the implementations of messengers behind existing handlers or write new messengers that implement new effects and compose correctly with the rest of the library.
