languages not loaded

[Evgeni Dimitrov]

Hello,
At
https://github.com/tesseract-ocr/tesseract/wiki

I saw there is a windows installer for Tesseract 3.05-dev from Tesseract at UB Mannheim at
https://github.com/UB-Mannheim/tesseract/wiki

I installed it. It works with English. On the last page there is a link to "download the appropriate training data" for another language at
https://github.com/tesseract-ocr/tessdata

On this page it says "These language data files only work with Tesseract 4. Get language data files for Tesseract 3.04 or 3.05 from the 3.04 tree.". The new link is:
https://github.com/tesseract-ocr/tessdata/tree/3.04.00

I downloaded from there bul.traineddata and deu.traineddata and copied to
. . . \Tesseract-OCR\tessdata
. Now tesseract --list-langs shows
bul
deu
eng
osd

But it works really with English. For Bulgarian and for German the message is:
Failed loading language 'deu'
Tesseract couldn't load any languages!
Could not initialize tesseract.

Any advice - what could be wrong?

check the value of TESSDATA-PREFIX environment variable and what traineddata files are in that location.

Thank you ShreeDevi,

I tried first time with TESSDATA-PREFIX pointing to
xxx\Tesseract-OCR

I tried second time with TESSDATA-PREFIX pointing to
xxx\Tesseract-OCR\tessdata

I have in xxx\Tesseract-OCR\tessdata:
configs, tessconfigs, bul.traineddata, deu.traineddata, eng.cube.bigrams, eng.cube.fold, eng.cube.lm, eng.cube.nn, eng.cube.params, eng.cube.size, eng.cube.word-freq, eng.tesseract_cube.nn, eng.traineddata, eng.user-patterns, eng.user-words, osd.traineddata, pdf.ttf

In both cases the result is as described above.

Best regards
Evgeni

check the size of the traineddata files and match against the repo to confirm that they were downloaded correctly.
