Hey guys,
It is not generating the ocr within the Alfresco platform.

Thanks a lot!

You can  tested the command directly in the shell using an exmaple file  and see what happens

/opt/alfresco/scripts/ocrmypdf.sh --verbose 1 --force-ocr -l por+eng /***/***src.pdf  /***/***target.pdf

Hi kaynezhang,
Running through the linux shell, it worked perfectly.

It just doesn't generate through the Alfresco platform.

Can you help?
Thank you.

[kaynezhang]

How did you install alfresco ? did you install it manually or install using docker?

[jbrasil]

Hi kaynezhang,
I installed using the loftuxab script.
alfinstall.sh

https://github.com/loftuxab/alfresco-ubuntu-install

I have always installed this script.
I never had a problem. First time this type of error occurs.
Anything else that needs to be investigated?
Thanks a lot.

[kaynezhang]

Your  installation is ok ,the error seems python script can't load tesseract lib correctly. But you can run the command successfully directly int shell,very strange.

[jbrasil]

Hi kaynezhang,
Very strange. We have other servers with Alfrescom running the same version.
See the script:

/ opt / alfresco / scripts

cat ocrmypdf.sh
#! / usr / bin / env bash
# set -o xtrace # Uncomment for debugging / troubleshooting
sudo ocrmypdf "$ @"

Theoretically, it is right.
I do not know what happened...
Thanks.
