Re: [tesseract-ocr] How to install tesseract 5.2.0 in docker container

[Alejandro Nadal]

Hi

You should set up the TESSDATA_PREFIX variable aiming to the folder where tesseract is being installed.

Check this: https://github.com/AlejandroFNadal/ia_ds_newspaper_analysis/blob/main/lambda/newspaper-to-img-title/build_tesseract.sh

and this: https://github.com/AlejandroFNadal/ia_ds_newspaper_analysis/blob/main/lambda/newspaper-to-img-title/Dockerfile

There I have successfully build a docker that runs tesseract

Good luck

Alejandro

Hi All,

Locally I tried 'brew install tesseract' and it installed 5.2.0.

Following 2 commands installed version 5.1.0

RUN add-apt-repository ppa:alex-p/tesseract-ocr5

RUN apt install -y tesseract-ocr

Then I downloaded source code tesseract-5.2.0.tar.gz and followed steps in install file:

RUN apt-get install -y libleptonica-dev
RUN ./autogen.sh &&\
./configure  &&\
make &&\
make install

This installs 5.2.0 but gives error:

 pytesseract.pytesseract.TesseractError: (1, 'Error opening data file /usr/local/share/tessdata/eng.traineddata Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory. Failed loading language \'eng\' Tesseract couldn\'t load any languages! Could not initialize tesseract.')

Any help would be really appreciated.

Thanks
