[Bug]: crashes with tesseract 5.4.0 about ocrmypdf

[jbarlow83]

This is a tesseract issue - we will need to wait for them resolve it
tesseract-ocr/tesseract#4257

Since the issue is with Tesseract itself, downgrading is the only option at the moment

The bug is in the the legacy engine.

It's not the only option, unless ypu want Tesseract to use the legacy engine.

You can bypass this bug by using a model from the tessdata_fast repo or by using oem 1.

@amitdo ocrmypdf uses orientation and script detection (osd.traineddata) which currently only has the legacy option even in tessdata_fast. Your workaround will help people looking to get tesseract 5.4.0 working on OCR (without using any feature that requires page orientation detection) but it's not a full solution.

For maintainers looking for a full solution that passes the test suite, unfortunately ocrmypdf with tesseract 5.4.0 is not workable and will have to wait for 5.4.1.

Yeah, I forgot about OSD.

I just updated tesseract to version 5.4.1-1 on Arch Linux and the problem is gone.

For's for me aswell... ArchLinux w/ ocrmypdf 16.3.1-1 + tesseract 5.4.1-1

[jbarlow83]

In 16.4.0 we refuse to use tesseract 5.4.0. 5.4.1 with any version works.
