I upgraded from Ubuntu 16 to Ubuntu 18, and now something no longer works :
loading a document - jpg or pdf, works well
selecting an area for ocr also works
ocr in vietnamese or in french work ok
ocr in bambara, a west african language with a few special latin characters, which I setup already 4 years ago and use regularly, ... stopped working:
On screen, it takes time (more than usual) displaying "OCR running" (bottom left)
Then the whole display disappears ans I get this error message in Terminal (see below).
what do I need to do ? re-install ? upgrade my bambara files (how to?) ...
Thanks for help!

Your old traineddata is not compatible with Tesseract 4.0's new LSTM engine. You can either retrain it using the new technique or use the OCR Engine Mode 0 (Legacy engine only).

thanks for help, but setting to Legacy did not work.
seeting to LTSM crashes much faster, that's clear, and the error message is just the same.
Unfortunately, I have no time to retrain just now... Legacy mode was a ray of hope, but alas...
