I'm trying to use ocrMyPdf library and here is my code:
ocrmypdf.ocr("input/mypdf.pdf",
"input/mypdf_ocr.pdf",
skip_text=False,
force_ocr=True,
deskew=True,
rotate_pages=True,
remove_background=False,
rotate_pages_threshold=3,
pages="1,72",
max_image_mpixels=1_000_000_000,
keep_temporary_files=False,
pdf_renderer="sandwich",
unpaper_args="",
clean=True,
progress_bar=False,)
Above call is throwing PermissionError: [Errno 13] Permission denied: 'unpaper'. Not sure where to debug the cause of the error.
I'm using WSL2 (Ubuntu 20.4) on Windows 11.
Here is the full trace from jupyter notebook:
