# Argos Translate
[Demo](https://libretranslate.com) | [Website](https://www.argosopentech.com) | [Docs](https://argos-translate.readthedocs.io) | [Forum](https://community.libretranslate.com/c/argos-translate/5) | [GitHub](https://github.com/argosopentech/argos-translate) | [PyPI](https://pypi.org/project/argostranslate/)
**Open-source offline translation library written in Python**
Argos Translate uses [OpenNMT](https://opennmt.net/) 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](https://libretranslate.com) 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.
### Supported languages
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 argostranslate
```
Install [GUI](https://github.com/argosopentech/argos-translate-gui):
```
pip install argostranslategui
```
### Installation for macOS
1. Download the latest [macOS release.](https://github.com/argosopentech/argos-translate/releases/)
2. Extract the archive.
3. Copy the `.app` file to the Applications directory.
### Python source installation into virtualenv
Download a copy of this repo and install with pip.
```
git clone https://github.com/argosopentech/argos-translate.git
cd argos-translate
virtualenv env
source env/bin/activate
pip install -e .
```
## Examples
### [Python](https://argos-translate.readthedocs.io/en/latest/py-modindex.html)
```python
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!'
```
### Command Line Interface
```
argospm update
argospm install translate-en_de
argos-translate --from en --to de "Hello World!"
# Hallo Welt!
```
Install all translation packages:
```
argospm install translate
```
### [LibreTranslate](https://github.com/LibreTranslate/LibreTranslate) Web App ([Demo](https://libretranslate.com/))
### [LibreTranslate](https://github.com/uav4geo/LibreTranslate) API
```javascript
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](https://github.com/argosopentech/argos-translate-gui).
## [Packages](https://www.argosopentech.com/argospm/index/)
- [Browse](https://www.argosopentech.com/argospm/index/)
- [P2P download (IPFS and BitTorrent)](/p2p/README.md)
- [Training scripts](https://github.com/argosopentech/argos-train)
- [Google Drive download](https://drive.google.com/drive/folders/11wxM3Ze7NCgOk_tdtRjwet10DmtvFu3i)
### 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](https://github.com/OpenNMT/CTranslate2).
### HTML Translation
The [translate-html](https://github.com/argosopentech/translate-html) library is built on top of Argos Translate and [Beautiful Soup](https://beautiful-soup-4.readthedocs.io/en/latest/) and parses and translates HTML. The LibreTranslate API also has support for translating HTML.
### Files Translation
The [argos-translate-files](https://github.com/LibreTranslate/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
``` shell
pip uninstall argostranslate
```
You may choose to also delete temporary and cached files:
``` shell
rm -r ~/.local/cache/argos-translate
rm -r ~/.local/share/argos-translate
```
