Creation of encoded unicharset failed While constructing LSTM training data.

[roberty...@gmail.com]

Hello,

I'm trying to finetune the end.traineddata model as the steps in the link: https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00#fine-tuning-for-%C2%B1-a-few-characters

As the tutorail shows, I fine tuning for ± a few characters following the steps.

But when I execute the first command, to generate new training and eval data:

training/tesstrain.sh --fonts_dir /usr/share/fonts --lang eng --linedata_only \
  --noextract_font_properties --langdata_dir ../langdata \
  --tessdata_dir ./tessdata --output_dir ~/tesstutorial/trainplusminus

An error is prompted: Creation of encoded unicharset failed! While constructing LSTM training data.

More details refer to the image.

Can you help me? Thanks.

​Seems to work fine for me.

Are you sure that you have relevant files in the  directories listed in that command?

check tessdata, langdata location.

Use tessdata/best/*.traineddata as the existing models.​
