arviz.CmdStanPySamplingWrapper

class arviz.CmdStanPySamplingWrapper(data_file, **kwargs)

CmdStanPy sampling wrapper base class.

See the documentation on SamplingWrapper for a more detailed description. An example of CmdStanPySamplingWrapper usage can be found in the Refitting CmdStanPy models with ArviZ notebook.

Warning

Sampling wrappers are an experimental feature in a very early stage. Please use them with caution.
