httpstan.services_stub

Call and process output of stan::services functions.

Functions here perform the menial task of calling (from Python) a named C++ function in stan::services given a specific Stan model. The output of the stan::services function is routed from stan::callbacks writers into Python via a Unix domain socket.

Call stan::services function.

Yields (asynchronously) messages from the stan::callbacks writers which are written to by the stan::services function.

This is a coroutine function.

Parameters

  • function_name – full name of function in stan::services

  • services_module (module) – model-specific services extension module

  • fit_name – Name of fit, used for saving length-prefixed messages

  • logger_callback – Callback function for logger messages, including sampling progress messages

  • kwargs – named stan::services function arguments, see CmdStan documentation.
