See [1]. Your posts indicate that you moved tesseract to other place (e.g. you broke your installation). Now you blame tesseract ;-) You get error "Error openning data file" it means that it can not find requested data file because of: 1. TESSDATA_PREFIX point to "wrong" place - you can check it in command line (after you received this error) with command: echo %TESSDATA_PREFIX% 2. TESSDATA_PREFIX points to correct place, but the file did not exists. You can check it by command: dir "%TESSDATA_PREFIX%tessdata" There is report that if you change/remove TESSDATA_PREFIX (via regedit or via My Computer -> Properties ->...) there is need to restart computer. If you need to change it just for opened command line session, you can do it with command: set TESSDATA_PREFIX="your desired path\" [1] http://code.google.com/p/tesseract-ocr/source/browse/trunk/vs2008/tesseract.nsi#210 -- Zdenko > > > On Apr 12, 6:59 pm, caudex <[email protected]> wrote: > > After installing tesseract-ocr 3.0 successfully and running it > > against 3 or 4 pdfs, I now get the following error > > > > C:\tesseract\Tesseract-OCR>tesseract ocr_107.tif beglat > > Error openning data file C:\Program Files\Tesseract-OCR\tessdata/ > > eng.traineddata > > > > A dir on ...\tessdata shows: > > > > 10/03/2010 08:01a 1,926,792 eng.traineddata > > > > Notice the misspelling of openning and the / instead of \ in the > > qualified path to eng.traineddata. > > > > Does any of you have a clue what could be going wrong here after it > > worked correctly a few times? > > I see that tesseract is looking for the tessdata subdirectory in the > > wrong place (Program Files) instead of the current directory (where > > the .tif's were created) but how did it work the first three times? > > Under program files there is no tesseract-ocr subdirectory. > > > > Thanks, > > > > Ed > > -- > You received this message because you are subscribed to the Google Groups > "tesseract-ocr" group. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]. > For more options, visit this group at > http://groups.google.com/group/tesseract-ocr?hl=en. > > -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
