qibocal.auto package#

Autocalibration runner.

Submodules#

qibocal.auto.execute module#

Tasks execution.

qibocal.auto.execute.PLATFORM_DIR = 'platform'#: Folder where platform will be dumped.

qibocal.auto.execute._register(name: str, obj)[source]#

With a small abuse of the Python module system, the object is registered as a module, with the given name. name may contain dots, cf. Executor.name for clarifications about their meaning.

Note

This is mainly used to register executors, such that the protocols can be bound to it through the import keyword, in order to construct an intuitive syntax, apparently purely functional, maintaining the context in a single Executor “global” object.

class qibocal.auto.execute.Executor(history: History, targets: Union[list[Union[str, int]], list[Tuple[Union[str, int], Union[str, int]]], list[tuple[Union[str, int], ...]]], platform: Platform, update: bool = True, name: Optional[str] = None, path: Optional[Path] = None, meta: Optional[Metadata] = None)[source]#

Bases: object

Execute a tasks’ graph and tracks its history.

history: History#: The execution history, with results and exit states.

targets: Union[list[Union[str, int]], list[Tuple[Union[str, int], Union[str, int]]], list[tuple[Union[str, int], ...]]]#: Qubits/Qubit Pairs to be calibrated.

platform: Platform#: Qubits’ platform.

update: bool = True#: Runcard update mechanism.

name: Optional[str] = None#

Symbol for the executor.

This can be used generically to distinguish the executor, but its specific use is to register a module with this name in sys.modules. They can contain dots, ., that are interpreted as usual by the Python module system.

Note

As a special case, mainly used for internal purposes, names starting with . are also allowed, and they are interpreted relative to this package (in the top scope).

path: Optional[Path] = None#

meta: Optional[Metadata] = None#

classmethod create(name: str, platform: Optional[Union[Platform, str]] = None)[source]#: Load list of protocols.

run_protocol(protocol: ~qibocal.auto.operation.Routine, parameters: ~qibocal.auto.task.Action, mode: ~qibocal.auto.mode.ExecutionMode = ExecutionMode.None) → Completed[source]#: Run single protocol in ExecutionMode mode.

_wrapped_protocol(protocol: Routine, operation: str)[source]#

Create a bound protocol.

Returns a closure, already wrapping the current Executor instance, but specific to the protocol chosen. The parameters of this wrapper function maps to protocol’s ones, in particular:

the keyword argument mode is used as the execution mode (defaults to AUTOCALIBRATION)

the keyword argument id is used as the id for the given operation (defaults to protocol identifier, the same used to import and invoke it)

then the protocol specific are resolved, with the following priority:

explicit keyword arguments have the highest priorities

items in the dictionary passed with the keyword parameters

positional arguments, which are associated to protocols parameters in the same order in which they are defined (and documented) in their respective parameters classes

Attention

Despite the priority being clear, it is advised to use only one of the former schemes to pass parameters, to avoid confusion due to unexpected overwritten arguments.

E.g. for:

resonator_spectroscopy(1e7, 1e5, freq_width=1e8)

the freq_width will be 1e8, and 1e7 will be silently overwritten and ignored (as opposed to a regular Python function, where a TypeError would be raised).

The priority defined above is strictly and silently respected, so just pay attention during invocations.

unload()[source]#: Unlist the executor from available modules.

init(path: PathLike, force: bool = False, platform: Optional[Union[Platform, str]] = None, update: Optional[bool] = None, targets: Optional[Union[list[Union[str, int]], list[Tuple[Union[str, int], Union[str, int]]], list[tuple[Union[str, int], ...]]]] = None)[source]#: Initialize execution.

close(path: Optional[PathLike] = None)[source]#: Close execution.

classmethod open(name: str, path: PathLike, force: bool = False, platform: Optional[Union[Platform, str]] = None, update: Optional[bool] = None, targets: Optional[Union[list[Union[str, int]], list[Tuple[Union[str, int], Union[str, int]]], list[tuple[Union[str, int], ...]]]] = None)[source]#: Enter the execution context.

qibocal.auto.history module#

Track execution history.

class qibocal.auto.history.History(_tasks: dict[qibocal.auto.task.Id, list[qibocal.auto.task.Completed]] = <factory>, _order: list[qibocal.auto.task.TaskId] = <factory>)[source]#

Bases: object

Execution history.

This is not only used for logging and debugging, but it is an actual part of the execution itself, since later routines can retrieve the output of former ones from here.

_tasks: dict[qibocal.auto.task.Id, list[qibocal.auto.task.Completed]]#: List of completed tasks.

Note

Representing the object as a map of sequences makes it smoother to identify the iterations of a given task, since they are already grouped together.

_order: list[qibocal.auto.task.TaskId]#: Record of the execution order.

_(key: TaskId) → Completed[source]#

values() → Iterator[Completed][source]#: Iterate individual tasks according to the execution order.

items() → Iterator[tuple[qibocal.auto.task.TaskId, qibocal.auto.task.Completed]][source]#: Consistent iteration over individual tasks and their ids.

push(completed: Completed) → TaskId[source]#: Adding completed task to history.

static route(task_id: TaskId, folder: Path) → Path[source]#

folder should be usually the general output folder, used by Qibocal to store all the execution results. Cf. :cls:`qibocal.auto.output.Output`.

Simple and general statuses are defined here, but more of them can be defined by individual calibrations routines, and user code as well:

class PinkFirst(Status):
    '''Follow the pink arrow as the next one.'''

@dataclass
class ParametrizedException(Status):
    '''Trigger exceptional workflow, passing down a further parameter.

    Useful if the handler function is using some kind of threshold, or can
    make somehow use of the parameter to decide, but in a way that is not
    completely established, so it should not be hardcoded in the status
    type.

    '''
    myvalue: int

@dataclass
class ExceptionWithInput(Status):
    '''Pass to next routine as input.'''
    routine_x_input: float

In general, statuses can encode a predetermined decision about what to do next, so the decision has been handled by the fitting function, or an open decision, that is left up to the handler function.
