Do you have clue what are you doing? Why are you trying to train legacy engine (tesseract <=3.x) with tesseract 5? What are you expecting to get?

[amitdo]

The training tools for the legacy OCR engine were broken since version 5.0. They were fixed recently.

Try the latest code in the main branch of this repo, or wait for v5.3.0, which will be released soon.
