See how each library processes a document in Python:
from google.cloud import documentai_v1 as documentai
client = documentai.DocumentProcessorServiceClient()
name = client.processor_path('project_id', 'us', 'processor_id')
with open('invoice.pdf', 'rb') as f:
raw_document = documentai.RawDocument(content=f.read(), mime_type='application/pdf')
request = documentai.ProcessRequest(name=name, raw_document=raw_document)
result = client.process_document(request=request)
print(result.document.text)import olmocr
from olmocr.pipeline import process_page
# Process complex ArXiv paper with LaTeX math
result = process_page("complex_paper.pdf", page_num=1, model="allenai/olmOCR-7B-0225-preview")
