## Example Usage

```python
from transformers import pipeline

# Load the model
model_checkpoint = "ParitKansal/marian-finetuned-kde4-en-to-fr"
translator = pipeline("translation", model=model_checkpoint)

# Translate text
translation = translator("Default to expanded threads")
print(translation)
```
