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.

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:
