If you want to make changes to the code, you can build from source, and run the API.
|
||
|
||
## Build Dependencies
|
||
|
||
* cmake
|
||
|
||
### Debian / Ubuntu
|
||
|
||
```sh
|
||
sudo apt-get install cmake
|
||
```
|
||
|
||
### Fedora / RHEL
|
||
|
||
```sh
|
||
sudo dnf install cmake
|
||
```
|
||
|
||
## Getting Started
|
||
|
||
Install [`hatch`](https://hatch.pypa.io) to manage the projects dependencies and run dev scripts:
|
||
|
||
```bash
|
||
pipx install hatch
|
||
```
|
||
|
||
Clone the repository:
|
||
|
||
```bash
|
||
git clone https://github.com/LibreTranslate/LibreTranslate.git
|
||
cd LibreTranslate
|
||
```
|
||
|
||
Hatch will automatically install the required dependencies in a virtual environment, and enable [`pre-commit`](https://pre-commit.com/), which will run before each commit to run formatting. You can ignore `pre-commit` checks when committing if necessary: `git commit --no-verify -m "Fix"`
|
||
|
||
Run in development:
|
||
|
||
```bash
|
||
hatch run dev --debug
|
||
```
|
||
|
||
Then open a web browser to <http://localhost:5000>
|
||
|
||
You can also start a new shell in a virtual environment with libretranslate installed:
|
||
|
||
```bash
|
||
hatch shell
|
||
libretranslate [args]
|
||
# Or
|
||
python main.py [args]
|
||
```
|
||
|
||
> You can still use `pip install -e ".[test]"` directly if you don't want to use hatch.
|
||
|
||
## Run the tests
|
||
|
||
Run the test suite and linting checks:
|
||
|
||
```bash
|
||
hatch run test
|
||
```
|
||
|
||
To display all `print()` when debugging:
|
||
|
||
```bash
|
||
hatch run test -s
|
||
```
|
||
|
||
You can also run the tests on multiple python versions:
|
||
|
||
```bash
|
||
hatch run all:test
|
||
```
|
||
|
||
You can clean the virtual environment with:
|
||
|
||
```bash
|
||
hatch env prune
|
||
```
|
||
|
||
## Run with Docker
|
||
|
||
Linux/macOS: `./run.sh [args]`
|
||
Windows: `run.bat [args]`
|
||
|
||
Then open a web browser to <http://localhost:5000>
|
||
|
||
## Build with Docker
|
||
|
||
```bash
|
||
docker build -f docker/Dockerfile [--build-arg with_models=true] -t libretranslate .
|
||
```
|
||
|
||
If you want to run the Docker image in a complete offline environment, you need to add the `--build-arg with_models=true` parameter. Then the language models are downloaded during the build process of the image. Otherwise, these models get downloaded on the first run of the image/container.
|
||
|
||
Run the built image:
|
||
|
||
```bash
|
||
docker run -it -p 5000:5000 libretranslate [args]
|
||
```
|
||
|
||
Or build and run using Docker Compose:
|
||
|
||
```bash
|
||
docker compose up -d --build
|
||
```
|
||
|
||
> Feel free to change the [`docker-compose.yml`](https://github.com/LibreTranslate/LibreTranslate/blob/main/docker-compose.yml) file to adapt it to your deployment needs, or use an extra `docker-compose.prod.yml` file for your deployment configuration.
|
||
>
|
||
> The models are stored inside the container under `/home/libretranslate/.local/share` and `/home/libretranslate/.local/cache`. Feel free to use volumes if you do not want to redownload the models when the container is destroyed. To update the models, use the `--update-models` argument.

## FAQ
|
||
|
||
### Externally Managed Environment
|
||
|
||
Some users may encounter the following error while installing packages:
|
||
|
||
```
|
||
error: externally-managed-environment
|
||
|
||
× This environment is externally managed
|
||
╰─> To install Python packages system-wide, try apt install
|
||
python3-xyz, where xyz is the package you are trying to
|
||
install.
|
||
|
||
…
|
||
```
|
||
|
||
This occurs when your operating system depends on and manages Python for core functionality. In this case, you should install and setup venv (virtual environments) to manage project dependencies.
|
||
|
||
This prevents pip packages from being installed system-wide. This way, there are no risks of pip packages conflicting between multiple projects or the operating system.
