Other Information

I tried with tesseract v.5.3.1 but same error occurs. It was confirmed that tif, box, and traineddata were created and recognized well by tess4j, but this is an error that occurs when performing lstmtraining. Could it be cpu related?

1. Try to use the latest tesseract version
2. Can you provide minimum data/files for reproducing the problem?
