columnflow.production

columnflow.production#

Tools for producing new array columns (e.g. high-level variables).

Classes:

TaskArrayFunctionWithProducerRequirements(...)

Producer(*args, **kwargs)

Base class for all producers.

Functions:

producer([func, bases, mc_only, data_only, ...])

Decorator for creating a new Producer subclass with additional, optional bases and attaching the decorated function to it as call_func().
class TaskArrayFunctionWithProducerRequirements(*args, **kwargs)[source]#

Bases: TaskArrayFunction

Attributes:

require_producers

cache_instances

Methods:

requires_func(task, reqs, **kwargs)

Default requires function.

setup_func(task, reqs, inputs, ...)

Default setup function.
require_producers: Sequence[str] | set[str] | None = None#
requires_func(task, reqs, **kwargs)[source]#

Default requires function.

Return type:

None

setup_func(task, reqs, inputs, reader_targets, **kwargs)[source]#

Default setup function.

Return type:

None

cache_instances = True#
class Producer(*args, **kwargs)[source]#

Bases: TaskArrayFunctionWithProducerRequirements

Base class for all producers.

Attributes:

exposed

mc_only

data_only

cache_instances

Methods:

producer([func, bases, mc_only, data_only, ...])

Decorator for creating a new Producer subclass with additional, optional bases and attaching the decorated function to it as call_func().
exposed = True#
mc_only: bool = False#
data_only: bool = False#
classmethod producer(func=None, bases=(), mc_only=<object object>, data_only=<object object>, require_producers=<object object>, **kwargs)[source]#

Decorator for creating a new Producer subclass with additional, optional bases and attaching the decorated function to it as call_func().

When mc_only (data_only) is True, the producer is skipped and not considered by other calibrators, selectors and producers in case they are evaluated on a order.Dataset (using the dataset_inst attribute) whose is_mc (is_data) attribute is False.

All additional kwargs are added as class members of the new subclasses.

Parameters:

  • func (Callable | None, default: None) – Function to be wrapped and integrated into new Producer class.

  • bases (tuple, default: ()) – Additional bases for the new Producer.

  • mc_only (bool | UNSET_TYPE, default: <object object at 0x7d22b4d86760>) – Boolean flag indicating that this Producer should only run on Monte Carlo simulation and skipped for real data.

  • data_only (bool | UNSET_TYPE, default: <object object at 0x7d22b4d86760>) – Boolean flag indicating that this Producer should only run on real data and skipped for Monte Carlo simulation.

  • require_producers (Sequence[str] | set[str] | None | UNSET_TYPE, default: <object object at 0x7d22b4d86760>) – Sequence of names of other producers to add to the requirements.

Return type:

DerivableMeta | Callable

Returns:

New Producer subclass.
