Function: createMarianTranslator()

createMarianTranslator(config, runtime?): Promise<MarianTranslator>

Defined in: extensions/nlp/tasks/marianTranslation.ts:87

The source sentence is encoded once into per-layer cross-attention keys and values, then decoded greedily one token at a time, starting from the pad token, until the end-of-sentence token. Sentences longer than the model's maximum source length are truncated.

Parameters

config

MarianTranslatorModel

Model and tokenizer paths. See MarianTranslatorModel.

runtime?

any

Optional worklet runtime thread on which to run the model execution.

Returns

Promise<MarianTranslator>

A promise resolving to the instantiated MarianTranslator.

Throws

With code LOAD_FAILED if the model or tokenizer fails to load, or SCHEMA_MISMATCH if the model schema does not match the Marian specification.
