LibreTranslate

transpolibre uses a LibreTranslate server for translations.

Local Server

You can run your own LibreTranslate server.

Server Installation

To install your own server, you can do it thusly on Debian:

sudo apt install python3-venv python-is-python3
mkdir libretranslate
cd libretranslate/
python -m venv venv
source venv/bin/activate
pip install -U setuptools pip wheel
pip install libretranslate

Note, the first time it is run, it will download the translation models. The web URL won’t be available until this is complete. It will download (currently) approximately 9 gigs of data.

Translation model files download to here:

~/.local/share/argos-translate/packages

systemd

You can set up the server to start on boot with systemd. It will need a startup script and a systemd file.

Edit the systemd service file:

${EDITOR} /etc/systemd/system/libretranslate.service

Add contents such as this, adjusting path and user to where you put the startup script:

[Unit]
Description=LibreTranslate
After=network-online.target
Wants=network-online.target

[Service]
ExecStart=/usr/local/bin/libretranslate-start
WorkingDirectory=/tmp
User=debian
Group=debian
Restart=no
ExecReload=/bin/kill -HUP $MAINPID

[Install]
WantedBy=multi-user.target

Create the startup script:

${EDITOR} /usr/local/bin/libretranslate-start

Add contents such as this, adjusting to the correct path:

#!/bin/bash

cd /home/debian/libretranslate

source venv/bin/activate

libretranslate \
  --host 0.0.0.0 \
  --port 8000 \
  --frontend-language-source en \
  --frontend-language-target es \
  --update-models

Web Access
