I am on KNIME 2.9.1 on a Mac and trying to just try the example workflow provided from the Tesseract Community Webpage, however the workflow fails on the Tess4J node with the error below, and suggestions;
ERROR Tess4J Execute failed: Unable to load library 'tesseract': Native library (darwin/libtesseract.dylib) not found in resource path (/Applications/knime/Knime.app/Contents/MacOS//../../../plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar)
ERROR Tess4J Execute failed: Could not initialize class net.sourceforge.tess4j.TessAPI
Can you tell us more details about your configuration and error message? This thread was already resolved some years or months ago, so your error must be new.
we think this has something to do with the general problems we currently have on MAC. We will investigate the problem and come back to you as soon as possible.
I am on KNIME 3.3.1 on Windows and trying to run the example workflow knime://LOCAL/Example%20Workflows/99_Community/03_Tess4J/01_Tess4J, however the workflow fails on the Tess4J node with the error below,
WARN MISSING Tess4J 0:4 Node can't be executed - Node "Tess4J" not available from extension "KNIME Image Processing - Tess4J Integration" (provided by "University of Konstanz"; plugin "org.knime.knip.tess4j.base" is not installed)

I have installed 'Knime Community Contributions - Image Processing and Analysis' before run the example .
You additionally have to install KNIME Image Processing - Tess4J from the Stable Community contributions (see https://tech.knime.org/book/knime-image-processing-tesseract-ocr-extension). Please find more information here https://tech.knime.org/wiki/install-knime-image-processing (Step 2.2).
