CONFUSING! About Optional: OCRMyPDF

[ckgithub2019]

1. What's the relation between OCRMyPDF and marker-pdf?
2. If I install OCRMyPD and related packages, what could it do?
3. If I only install OCRMyPD, do I need to install marker-pdf?
4. Why does it need to run apt-get install ocrmypdf and run pip install ocrmypdf?

marker doesn't do the OCR itself, it depends on Surya by default or OCRMyPDF as another option.

If you use Surya, you dont need to install ocrmypdf.

Thanks. When or in what scenarios is OCR installation necessary?

It's not necessary - it's an option if you want to use tesseract for some reason (I wouldn't recommend it)
