lib.theory.base.BasePTModel

class lib.theory.base.BasePTModel(pklin, klin=None, FoG='gaussian')

Bases: lib.theory.base.BaseModel

Base class to represent perturbation theory model.

Initialize BasePTModel.

Parameters

• pklin (array, callable, PowerSpectrumInterpolator1D) – Linear power spectrum. If array, klin must be provided.

• klin (array, default=None) – Wavenumbers. Must be provided if pklin is an array.

• FoG (callable, string, default='gaussian') – Type of Finger-of-God effect.

Methods

copy	Return shallow copy of self.
deepcopy
from_state	Instantiate and initalize class with state dictionary.
is_mpi_broadcast
is_mpi_gathered
is_mpi_root
is_mpi_scattered
load	Load class in numpy binary format from disk.
load_auto	If different formats are possible, this method should between them based on file name extension.
log_critical
log_debug
log_error
log_info
log_warning
save	Save class to disk.
save_auto	If different formats are possible, this method should between them based on file name extension.

__call__(*args, **kwargs)

Evaluate model.

copy()

Return shallow copy of self.

classmethod from_state(state, mpiroot=0, mpicomm=None)

Instantiate and initalize class with state dictionary.

classmethod load(filename, mpiroot=0, mpicomm=None)

Load class in numpy binary format from disk. If the loaded state contains __class__ and that exists in cls._registry, return instance of cls._registry[__class__] (instead of cls).

load_auto(*args, **kwargs)

If different formats are possible, this method should between them based on file name extension.

property mpiattrs

MPI attributes

save(filename)

Save class to disk.

save_auto(*args, **kwargs)

If different formats are possible, this method should between them based on file name extension.
