pdf processing with OCR is stuck

[pradyrk]

Question

I am processing single pdf of 4 MB with the below OCR options ,

pipeline_options = PdfPipelineOptions()
pipeline_options.do_ocr = True
pipeline_options.do_table_structure = True
pipeline_options.table_structure_options.do_cell_matching = True
ocr_options = TesseractCliOcrOptions(force_full_page_ocr=True)
pipeline_options.ocr_options = ocr_options

Process is running indefinitely for hours , I am not sure whether its something to do with files , its pptx file converted to pdf , use-case is to extract the complex tables

I tried using accelarator options, tried both CPU and GPU , it doesnt help too.

accelerator_options = AcceleratorOptions(
num_threads=8, device=AcceleratorDevice.CPU
)

How do I address this issue ? Is there a way to process pages within PDF in-parallel ?
