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.
Arabic, Azerbaijani, Catalan, Chinese, Czech, Danish, Dutch, English, Esperanto, Finnish, French, German, Greek, Hebrew, Hindi, Hungarian, Indonesian, Irish, Italian, Japanese, Korean, Persian, Polish, Portuguese, Russian, Slovak, Spanish, Swedish, Turkish, Ukrainian, and more

pip install -e .
import argostranslate.package
import argostranslate.translate
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!'argospm update

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!"
}The GUI code is in a separate repository.
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.
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.
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.
