bilby.core.utils.parallel.initialize_global_variables

bilby.core.utils.parallel.initialize_global_variables(likelihood, priors, search_parameter_keys, use_ratio, parameters)

Store a global copy of the likelihood, priors, and search keys for multiprocessing.

Parameters:

likelihood: bilby.core.likelihood.Likelihood

The likelihood to copy into each process

priors: bilby.core.prior.PriorDict

The Bilby prior dictionary to copy into each process

search_parameter_keys: list[str], None

The names for parameters being sampled over

use_ratio: bool

Whether to evaluate the log_likelihood_ratio

parameters: dict

A set of default parameters to pass through to the new processes, e.g., if there are fixed parameters that the sampler used doesn’t use.
