Run CmdStan's generate_quantities method which runs the generated
quantities block of a model given an existing sample.
This function takes a CmdStanMCMC object and the dataset used to
generate that sample and calls to the CmdStan ``generate_quantities``
method to generate additional quantities of interest.
The ``CmdStanGQ`` object records the command, the return code,
and the paths to the generate method output csv and console files.
The output files are written either to a specified output directory
or to a temporary directory which is deleted upon session exit.
Output filenames are composed of the model name, a timestamp
in the form YYYYMMDDhhmm and the chain id, plus the corresponding
filetype suffix, either '.csv' for the CmdStan output or '.txt' for
the console messages, e.g. `bernoulli_ppc-201912081451-1.csv`. Output
files written to the temporary directory contain an additional
8-character random string, e.g.
`bernoulli_ppc-201912081451-1-5nm6as7u.csv`.
:param data: Values for all data variables in the model, specified
either as a dictionary with entries matching the data variables,
or as the path of a data file in JSON or Rdump format.
:param mcmc_sample: Can be either a CmdStanMCMC object returned by
CmdStanPy's `sample` method or a list of stan-csv files generated
by fitting the model to the data using any Stan interface.
:param seed: The seed for random number generator. Must be an integer
between ``0`` and ``2^32 - 1``. If unspecified,
``numpy.random.RandomState()``
is used to generate a seed which will be used for all chains.
*NOTE: Specifying the seed will guarantee the same result for
multiple invocations of this method with the same inputs. However
this will not reproduce results from the sample method given
the same inputs because the RNG will be in a different state.*

"""
Run or more chains of the NUTS sampler to produce a set of draws
from the posterior distribution of a model conditioned on some data.
This function validates the specified configuration, composes a call to
the CmdStan ``sample`` method and spawns one subprocess per chain to run
the sampler and waits for all chains to run to completion.
Unspecified arguments are not included in the call to CmdStan, i.e.,
those arguments will have CmdStan default values.
For each chain, the ``CmdStanMCMC`` object records the command,
the return code, the sampler output file paths, and the corresponding
console outputs, if any. The output files are written either to a
specified output directory or to a temporary directory which is deleted
upon session exit.
The output filenames are composed of the model name, a timestamp
in the form YYYYMMDDhhmm and the chain id, plus the corresponding
filetype suffix, either '.csv' for the CmdStan output or '.txt' for
the console messages, e.g. `bernoulli-201912081451-1.csv`. Output files
written to the temporary directory contain an additional 8-character
random string, e.g. `bernoulli-201912081451-1-5nm6as7u.csv`.
:param data: Values for all data variables in the model, specified
either as a dictionary with entries matching the data variables,
or as the path of a data file in JSON or Rdump format.
:param chains: Number of sampler chains, should be > 1.
:param cores: Number of processes to run in parallel. Must be an
integer between 1 and the number of CPUs in the system.
If none then set automatically to `chains` but no more
than `total_cpu_count - 2`
:param seed: The seed for random number generator. Must be an integer
between ``0`` and ``2^32 - 1``. If unspecified,
``numpy.random.RandomState()``
is used to generate a seed which will be used for all chains.
When the same seed is used across all chains,
the chain-id is used to advance the RNG to avoid dependent samples.
:param chain_ids: The offset for the random number generator, either
an integer or a list of unique per-chain offsets. If unspecified,
chain ids are numbered sequentially starting from 1.
:param inits: Specifies how the sampler initializes parameter values.
Initialization is either uniform random on a range centered on 0,
exactly 0, or a dictionary or file of initial values for some or all
parameters in the model. The default initialization behavior will
initialize all parameter values on range [-2, 2] on the
_unconstrained_ support. If the expected parameter values are
too far from this range, this option may improve adaptation.
The following value types are allowed:
* Single number ``n > 0`` - initialization range is [-n, n].
* ``0`` - all parameters are initialized to 0.
* dictionary - pairs parameter name : initial value.
* string - pathname to a JSON or Rdump data file.
* list of strings - per-chain pathname to data file.
:param warmup_iters: Number of warmup iterations for each chain.
:param sampling_iters: Number of draws from the posterior for each
chain.
:param save_warmup: When True, sampler saves warmup draws as part of
the Stan csv output file.
:param thin: Period between saved samples.
:param max_treedepth: Maximum depth of trees evaluated by NUTS sampler
per iteration.
:param metric: Specification of the mass matrix, either as a
vector consisting of the diagonal elements of the covariance
matrix (``diag`` or ``diag_e``) or the full covariance matrix
(``dense`` or ``dense_e``).
If the value of the metric argument is a string other than
``diag``, ``diag_e``, ``dense``, or ``dense_e``, it must be
a valid filepath to a JSON or Rdump file which contains an entry
``inv_metric`` whose value is either the diagonal vector or
the full covariance matrix.
If the value of the metric argument is a list of paths, its
length must match the number of chains and all paths must be
unique.
:param step_size: Initial stepsize for HMC sampler. The value is either
a single number or a list of numbers which will be used as the
global or per-chain initial step_size, respectively.
The length of the list of step sizes must match the number of
chains.
:param adapt_engaged: When True, adapt stepsize and metric.
*Note: If True, ``warmup_iters`` must be > 0.*
:param adapt_delta: Adaptation target Metropolis acceptance rate.
The default value is 0.8. Increasing this value, which must be
strictly less than 1, causes adaptation to use smaller step sizes.
It improves the effective sample size, but may increase the time
per iteration.
:param fixed_param: When True, call CmdStan with argument
"algorithm=fixed_param" which runs the sampler without
updating the Markov Chain, thus the values of all parameters and
transformed parameters are constant across all draws and
only those values in the generated quantities block that are
produced by RNG functions may change. This provides
a way to use Stan programs to generate simulated data via the
generated quantities block. This option must be used when the
parameters block is empty. Default value is False.
:param output_dir: Name of the directory to with the CmdStan output
files are written. If unspecified, output files will be written
to a temporary directory which is deleted upon session exit.
:param save_diagnostics: Whether or not to save diagnostics. If True,
csv output files are written to
``<basename>-diagnostic-<chain_id>.csv.``, where ``<basename>``
is set with ``csv_basename``.
:param show_progress: Use tqdm progress bar to show sampling progress.
If show_progress=='notebook' use tqdm_notebook
(needs nodejs for jupyter).
