For a complete example see [gpu_standard_pipeline.py](../examples/gpu_standard_pipeline.py).
#### OCR engines
The current Docling OCR engines rely on third-party libraries, hence GPU support depends on the availability in the respective engines.
The only setup which is known to work at the moment is RapidOCR with the torch backend, which can be enabled via
```py
pipeline_options = PdfPipelineOptions()
pipeline_options.ocr_options = RapidOcrOptions(
backend="torch",
)
```
