Lstm training is not like legacy training. Please read the wiki pages regarding 4.0 training. I have given all sample commands there. There are 3 different ways of training.
Read the bash scripts regarding training to know more. tesstrain.sh with --linedata-only creates the box tiff pairs but only the lstmf file is saved in output dir. Without --linedata-only you will get 3.0 traineddata. There are multiple steps to be done using the lstmf files to create the final 4.0 traineddata. Since you want to write a tutorial, please do your own reading and trials first - excuse the brevity, sent from mobile On 12-Apr-2017 4:08 PM, <srns...@gmail.com> wrote: > Sorry, I have given wrong commands for arabic.
