Re: [tesseract-ocr] Re: Tesstrain.sh fails when provided > 7 tif/box pairs

Change the loop inside phase_I_generate_image() of tesseract_utils.sh to

local counter=0
for font in "${FONTS[@]}"; do
sleep 1
generate_font_image "${font}" &
let counter=counter+1
if [[ "${counter}" -ge par_factor ]]; then
  wait -n
fi
done
Current version has bash error, moreover you waste time with wait instead 
of wait -n

Re: [tesseract-ocr] What do iteration numbers mean in the train logging?

[bohdan . moskalevskyi]

Ok, it says it’s learning iteration, training iteration and sample 
iteration respectively. But what do those terms mean? How can one deduce an 
epoch?

Same here. I’m surprised this issue isn’t more common. Any solutions?
