Open-source offline translation library written in Python

Argos Translate uses OpenNMT for translations and can be used as either a Python library, command-line, or GUI application. Argos Translate supports installing language model packages which are zip archives with a ".

argosmodel" extension containing the data needed for translation. LibreTranslate is an API and web-app built on top of Argos Translate.

Argos Translate also manages automatically pivoting through intermediate languages to translate between languages that don't have a direct translation between them installed.

For example, if you have a es → en and en → fr translation installed you are able to translate from es → fr as if you had that translation installed.

This allows for translating between a wide variety of languages at the cost of some loss of translation quality.

The argospm-index repo contains metadata and download links to access pre-trained Argos Translate models.

from_code = "en" to_code = "es"

Download and install Argos Translate package

argostranslate . package . update_package_index () available_packages = argostranslate . package . get_available_packages () package_to_install = next ( filter ( lambda x : x . from_code == from_code and x .

to_code == to_code , available_packages ) ) argostranslate . package . install_from_path ( package_to_install . download ())

Translate

translatedText = argostranslate . translate . translate ( "Hello World" , from_code , to_code ) print ( translatedText )

'¡Hola Mundo!'

Command Line Interface

LibreTranslate Web App ( Demo )

LibreTranslate API

const res = await fetch ( "https://translate.argosopentech.com/translate" , { method : "POST" , body : JSON . stringify ( { q : "Hello!" , source : "en" , target : "es" } ) , headers : { "Content-Type" : "application/json" } } ) ;

console . log ( await res . json ( ) ) ;

{ "translatedText" : "¡Hola!" }

Graphical user interface

The GUI code is in a separate repository .

GPU Acceleration

To enable GPU support, you need to set the ARGOS_DEVICE_TYPE env variable to cuda or auto .

ARGOS_DEVICE_TYPE=cuda argos-translate --from-lang en --to-lang es "Hello World"

Hola Mundo

The above env variable passes the device type to CTranslate2 .

HTML Translation

The translate-html library is built on top of Argos Translate and Beautiful Soup and parses and translates HTML. The LibreTranslate API also has support for translating HTML.

Files Translation

The argos-translate-files library is built on top of Argos Translate and parses and translates files. The LibreTranslate API also has support for translating files.

Uninstall

pip uninstall argostranslate
