### Steps to reproduce

```python
ocr_options = TesseractOcrOptions()
device = AcceleratorDevice.AUTO

accelerator_options = AcceleratorOptions(
num_threads=2,
device=device,
)

pipeline_options = PdfPipelineOptions(
do_ocr=False,
ocr_options=ocr_options,
table_structure_options=TableStructureOptions(
mode=TableFormerMode.FAST, do_cell_matching=True
),
do_table_structure=True,
accelerator_options=accelerator_options,
artifacts_path=self.docling_artifacts_path or None,
)

converter = CustomDocumentConverter(
allowed_formats=DOCLING_ALLOWED_FORMATS,
format_options={
InputFormat.PDF: PdfFormatOption(
backend=PyPdfiumDocumentBackend,
pipeline_options=pipeline_options,
),
},
)

# Then invoked like this:
md_text = converter.convert()
```
