Hi Shree, Thanks for your reply. I replaced fontlist argument 'Impact Condensed' with 'DejaVu Sans' to create evalplusminus folder.
Then i ran the lstmeval command and i got this as output At iteration 0, stage 0, Eval Char error rate=0.024610566, Word error rate=0.086171938 Do i need to create new traineddata file? I have traineddata files in '/local/share/tessdata' for old data and 'tesstutorial/trainplusminus/eng' which is created for new data. Do i need to give TESSDATA_PREFIX='tesstutorial/trainplusminus/eng' instead of '/local/share/tessdata' Please guide me Thanks in advance, Harathi On Thursday, June 21, 2018 at 8:50:14 PM UTC-7, Harathi Surya wrote: > > Hi, > > I am trying to create .lstm files to finetune tesseract4.0.0 for new > characters.
