Error while creating training data for Japanese

[atuyosi....@gmail.com]

Hi, 

I'm trying to creating training data for Japanese (jpn.traineddata).

I run 'tesstrain.sh' with '--linedataonly' option, and the script has finished ( return code 0 ) .

But log file has contained some error messages ( repeated 22 times ).

```

$ ../tesseract-ocr/training/tesstrain.sh --fonts_dir /usr/share/fonts --lang jpn --linedata_only   --noextract_font_properties --langdata_dir ../langdata   --tessdata_dir /usr/local/share --output_dir ~/work/jpntrain

```

Error opening data file /usr/local/share/tessdata/jpn_vert.traineddata

Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory.

Failed loading language 'jpn_vert'

It seems that 'tesstrain.sh' requires 'jpn_vert.traineddata`, but this file not provide on tessdata repository.

How I get this file? Or, Can I substitute  'jpn.traineddata' for  'jpn_vert.traineddata' ?

I've found that there is `jpn_vert' directory on langdata repository, but only some config files.

Thanks.

jpn.config in langdata/jpn is loading jpn_vert as a sublanguage

tessedit_load_sublangs jpn_vert

You can try without that

Also look at the settings for jpn in training/language_specific.sh

You may need to change the following also ..

# The following fonts will be rendered vertically in phase I.

VERTICAL_FONTS=( \

    "TakaoExGothic" \ # for jpn

    "TakaoExMincho" \ # for jpn

    "AR PL UKai Patched" \ # for chi_tra

    "AR PL UMing Patched Light" \ # for chi_tra

    "Baekmuk Batang Patched" \ # for kor

    )

Hi ShreeDev,

Thank you for the quick response. 

I modified langdata/jpn/jpn.config and training/language_specific.sh as you suggested. 

Things went well. No error has occurred. 

Thanks.
