ERROR: [tesseract] read_params_file: Can't open txt

[dev-code-davis]

Hi, when OCRying a PDF I always get the following error for nearly every page:

ERROR - 56: [tesseract] read_params_file: Can't open txt

I tried to google it, but nothing comes up (txt part especially). Maybe someone has faced with something similar. What does txt stand for? Some text format?

Command called:

nice -19 env LANG=lv_LV.utf8 ocrmypdf -l lav+rus --rotate-pages --force-ocr --pdf-renderer tesseract --output-type pdf --sidecar - /tmp/input.pdf /tmp/output556.pdf

Thanks.

I suspect you have an old/unsupported version of Tesseract. What is tesseract --version?

Your installation could also be missing the file $tessroot/share/tessdata/configs/txt where $tessroot varies from platform to platfom.

I am running on CentOS 8.

Version is tesseract 5.0.0-beta-20210815.
Earlier it was tesseract 4.1.1

In both the versions this issue is coming.

What to do ?

[jbarlow83]

Does tessdata/configs/txt exist as mentioned above?

[pankajkumar2433]

No it doesn't exist.
From where to get it ?

I have installed tesseract from the source (tar.gz).

[jbarlow83]

I recommend using a version of tesseract provided by your Linux distribution or some third party packager that has solved these issues, rather than installing one from source. A source build is a special case.

[pankajkumar2433]

I installed as below->

dnf config-manager --add-repo https://download.opensuse.org/repositories/home:/Alexander_Pozdnyakov/CentOS_8/
rpm --import https://build.opensuse.org/projects/home:Alexander_Pozdnyakov/public_key
sudo dnf install tesseract

tessdata/configs/txt is present in "/usr/share/tesseract/4/tessdata/configs"

Issue is still coming.

[jbarlow83]

You may need to set the environment variable TESSDATA_PREFIX=/usr/share/tesseract/4 and ensure that your PATH env var gives priority to the new tesseract.

Awesome!!
It's working.

Hello,

I have the similar response

I am using best float tessdata files from: https://github.com/tesseract-ocr/tessdata_best/blob/main/eng.traineddata

also tried some of possibilities in #209

I am looking for the source of the issue ---> could someone help if understood the source. so I can work further.
