This time I ran the following command to try and prepare 1 font for training
src/training/tesstrain.sh --fonts_dir /usr/share/fonts --lang eng
--linedata_only --noextract_font_properties --langdata_dir
~/tesstutorial/langdata \
--tessdata_dir ~/tesstutorial/tesseract/tessdata --output_dir
~/tesstutorial/engtrain --fontlist "Courier New" --overwrite
This gets much further than the command in post titled "Unclear error
message when running tesstrain.sh".
It now ran for hours and resulted in this:
Page 3302

ERROR: Program tesseract failed. Abort.
Frankly this failure to get TessTutorial to work after 2 weeks of attempts
is rather unsatisfying. So are the uninformative messages.
What are the minimum system requirements for this to work? I am using
Ubuntu 16.04 in VirtualBox with 8Gb RAM and 4 cores.
