I do not include 'chi_tra' in my tessdata folder . What is it ? I have seen language-specific.sh

[이경준]

Hi i'm sorry to question oftenly. and lots of questions.

But, I must use tesseract 4.0 for my business .

plz understand my situations. I have lots of family to raise.


ealier you gave me a bash sciprt . In there tesstrain.sh (course) . it give me an error like


Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory.
Failed loading language 'chi_tra'
Error opening data file /usr/share/tesseract-ocr/4.00/tessdata/chi_tra.traineddata


Before, you gave me a conference . it froms the lang directory / kor.config.

in there #Fixes https://github.com/tesseract-ocr/tesseract/issues/1009
preserve_interword_spaces 1

tessedit_load_sublangs chi_tra
# New Segmentation search params


So I guess "tessedit_load_sublangs chi_tra" cause to error for executing "tesstrain.sh"

So I conclude(for solution) 1) Delete that sentence -> Is it right ? or what is the side-effect
                           

   I want to have 1 traineddata which is fine tuned and for 2 langugages (korean & English)

  so is it possible to add the sentece like  1-1)"tessedit_load_sublangs eng"-> Is it right? or possible???


In conclusion
1)
I do not want to see like error " Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory.
Failed loading language 'chi_tra'
Error opening data file /usr/share/tesseract-ocr/4.00/tessdata/chi_tra.traineddata "

2) If I want to use tessereract(4.0) for 2 languages(e.g. Korean, English) by 1(one) traineddata(which is fine tuned)

Is it possible and How to make 1 finedtuned traineddata for 2 languages(e.g Korean, English)

3) tesseract is possible to use like

$ tesseract (picture.png) -l kor+eng

is it possible ?????

4) What is kor.vert traineddata ? (tessdata-best)

What is different from kor.traineddata ???

5) Is it possible to fine tune by existing images??? How is it possible to use script you gave me

I hope someone who knows Korean can answer your questions.

2), 3):

I'm wondering about using tesseract 4.0 for multiple language, too.

After searching & testing a while, I found that it seems not working the old method for tesseract 3. (e.g. running with '-l lang1+lang2' option)

Is there any other method that I have to try?

Or I have to train tesseract with two languages at the same time?

Lang1+lang2 should work. If it does not, please open an issue with an example image.

If lang2 is English, you may want to try the script level traineddata, which includes English with the other languages . 

Please take a look at the readme file in tessdata_fast which explains about script level files in more details.
