How to install ocrmypdf?

[VooDisss]

Im running Windows 10. Currently given directions not elaborative enough. Please try to install ocrmypdf and use it with marker without getting errors. Where the hell do I find the root folder of marker if I installed it using command given below and not using some kind of visual studio environment (#316)?

1. Installed marker: pip install marker-pdf https://github.com/VikParuchuri/marker/blob/master/docs/install_ocrmypdf.md
2. Installed ocrmypdf: winget install -e --id Python.Python.3.11 winget install -e --id UB-Mannheim.TesseractOCR installed ghostscript python3 -m pip install ocrmypdf
3. set two variables for ocrmypdf to be used: set OCR_ALL_PAGES=true set OCR_ENGINE=ocrmypdf
4. trying to launch marker_single: marker_single input.pdf C:/output/folder --langs Greek,Lithuanian
5. Getting errors. 5.1 Trying to resolve: Introduced a new variable: set TESSDATA_PREFIX="C:\Program Files\Tesseract-OCR\tessdata"
6. Errors again, frustration starts and hopefully ends here (with your help).

In CMD I wrote (found it in #162): pip show marker-pdf Got this (bold is what I needed):

Name: marker-pdf Version: 0.3.10 Summary: Convert PDF to markdown with high speed and accuracy. Home-page: https://github.com/VikParuchuri/marker Author: Vik Paruchuri Author-email: github@vikas.sh License: GPL-3.0-or-later Location: C:\Users\Wasup\miniconda3\Lib\site-packages Requires: filetype, ftfy, pdftext, Pillow, pydantic, pydantic-settings, python-dotenv, rapidfuzz, regex, surya-ocr, tabled-pdf, tabulate, texify, torch, tqdm, transformers

Went to C:\Users\Wasup\miniconda3\Lib\site-packages and found undocumented settings.py file. Opened with notepad++ and found the needed lines and filled in the TESSDATA_PREFIX value:

OCR_PARALLEL_WORKERS: int = 2 # How many CPU workers to use for OCR TESSERACT_TIMEOUT: int = 20 # When to give up on OCR TESSDATA_PREFIX: str = "C:\Program Files\Tesseract-OCR\tessdata"

Now atleast marker recognizes that there is some kind of TESSDATA_PREFIX:
