If you want to train using text, then you also need to specify a set of fonts. eg.
~/tesseract/src/training/tesstrain.sh \ --fonts_dir ~/.fonts \ --lang ara \ --linedata_only \ --noextract_font_properties \ --langdata_dir ~/langdata \ --tessdata_dir ~/tessdata \ --fontlist "Amiri" \ "Amiri Bold Italic" \ "Amiri Bold" \ "Amiri Italic" \ --training_text ./ara.training_text \ --workspace_dir ~/tmp/ \ --save_box_tiff \ --output_dir ~/tesstutorial/araeval This will create a set of lstmf files and their list and those can be used for lstmtraining. If you don't want to use existing traineddata, then follow instructions to train from scratch - https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00#training-from-scratch Training from scratch will take a long time - days/weeks.
