OCRmyPDF in Databricks

kro
Visitor

Hello,

Do any of you have experience with using OCRmyPDF in Databricks? I have tried to install it in various was with different versions, but my notebook keep crashing with the error:

The Python process exited with exit code 139 (SIGSEGV: Segmentation fault).

I have made a minimal code example to test it:

import ocrmypdf
import io

with open('noocr.pdf', 'rb') as f:
    pdf = f.read()

pdf_bytes = io.BytesIO(pdf)
out_bytes = io.BytesIO()

ocrmypdf.ocr(
    pdf_bytes,
    out_bytes,
    language='dan',
    output_type="pdf",
    optimize=0,
    fast_web_view=9999999,
    force_ocr=True
    )

I have tried to narrow down the issue and it seems to vary when it crashes. Often, it happens when Tesseract is called as a subprocess, but also when it attempts to save the PDF to a temporary folder.

While debugging, it seems to work without errors when executing the code through the debugger.

Any suggestions would be greatly appreciated!
