Hello
I am using the Tess4J node to interpret some images to convert them to text. On my computer it runs fine, but when I try to run it on another pc I get the following error.
The extension is installed and I don’t know if it has some dependency that I can’t remember anymore. Could you help me to solve it, please?
Thanks
Hi @lsandinop ,
Which version of the KNIME Analytics Platform are you on currently and which version does it not work?
Also, could you please share a sample data, if possible, so that we can try to reproduce it on our end?
Thanks,
Sanket
Hi @sanket_2012
My current KNIME version is 5.2.2, and it is been working on my computer since 4.6. The KNIME version where it is not working, is 4.7.8.
I have to mention that I had a similar problem on that PC with a java snippet that had a library loaded in the node (commons-compress.jar). Even with the library loaded correctly, there was a piece of code that didn’t work because it didn’t find a component of the library. I’m telling you this in case this can help you to solve the problem.
Additionally, I attach the image of the error again, what I get from the failure in the Catch node, and the table that enters the node in question.

Hello @lsandinop ,
Apologies for the delayed reply, but I have asked about this internally. We will get back to you soon.
Thanks,

Hi @sanket_2012 ,
I have an issue too with the Tess4J node on KNIME Analytics Platform 5.2.3. Actually I can’t tell, if this happened in the prior versions, because I’ve just started using it. Mine is related to “Execute failed: Invalid memory access”. These actions I tried to solve the problem checking former conversations:
Download language package portuguese from tessdoc | Tesseract documentation and save in …knime_5.2.3\plugins\org.knime.knip.tess4j.base_1.3.3.v202307241154\tessdata
As this didn’t work, I saved the file in an external folder and tried again, indicating to this folder.
Then I tried to include the …\tessdata folder in the PATH of my environment.
And increased the memory register Xmx in the knime.ini.
All actions didn’t work out.
Afterwards I’ve downloaded a few example Tess4J workflows. Not even these I could run, showing the same issue.
Can you help me out with that? Do you have any other idea that I can try?
