class neurolang.utils.server.engines.NeurolangEngineConfiguration¶

Bases: object

A NeurolangEngineConfiguration is a combination of an id key and a method which returns a Neurolang instance.

Attributes:

atlas
key

Methods

abstract property atlas¶

abstract create() → NeurolangDL | NeurolangPDL¶

abstract property key¶

class neurolang.utils.server.engines.NeurolangEngineSet(engine: NeurolangDL | NeurolangPDL)¶

Bases: object

Utility class to hold a set of Neurolang engines (either NeurolangDL or NeurolangPDL). It keeps track of the total number of engines added to the set, as well as a semaphore to manage acquiring and releasing the engines in a safe concurrent manner.

Methods

`add_engine`(engine)	Add an engine to the set and increase the total number of engines in the set.
`engine`([timeout])	ContextManager to safely acquire an engine from the set.

add_engine(engine: NeurolangDL | NeurolangPDL) → None¶

Add an engine to the set and increase the total number of engines in the set.

Parameters:

engineUnion[NeurolangDL, NeurolangPDL]: the engine to add.

engine(timeout: int = None)¶

ContextManager to safely acquire an engine from the set. This method will block on the semaphore until an engine can be safely used from this set, and then yield it. At the end, the engine is put back in the set and the semaphore value is released.

Parameters:

timoutint: When invoked with a timeout other than None, it will block for at most timeout seconds.

Yields:

Union[NeurolangDL, NeurolangPDL]: an engine.

class neurolang.utils.server.engines.NeurosynthEngineConf(data_dir: Path, resolution=None)¶

Bases: NeurolangEngineConfiguration

Attributes:

atlas
brain_mask
key

Methods

create

property atlas¶

property brain_mask¶

create() → NeurolangPDL¶

property key¶

neurolang.utils.server.engines.add_ploting_functions(nl: NeurolangDL | NeurolangPDL)¶

neurolang.utils.server.engines.init_frontend(mni_mask)¶

Create a Neurolang Probabilistic engine and add some aggregation methods.

Returns:

NeurolangPDL: the Neurolang engine
