[tesseract-ocr] Re: Tesseract couldn't load any languages!
It is possible that you have not downloaded eng.traineddata or it is in a
different location.
Try running tesseract on command line, check --list-langs.

*[SOLVED] changed the language from 'hin+eng' to 'hin'In this case
selection of language also matters -* I was processing image with

As English text was less in the image so I changed lang=hin and I got the

You'll need to setDatapath to your tessdata directory so Tesseract can find the *.traineddata files On Friday, May 4, 2018 at 1:38:16 PM UTC-5, Dattatraya Tembare wrote: > > Exception in thread "main" java.lang.Error: Invalid memory access > at com.sun.jna.Native.invokePointer(Native Method) > at com.sun.jna.Function.invokePointer(Function.java:490) > at com.sun.jna.Function.invoke(Function.java:434) > at com.sun.jna.Function.invoke(Function.java:354) > at com.sun.jna.Library$Handler.invoke(Library.java:244) > at com.sun.proxy.$Proxy0.TessBaseAPIGetUTF8Text(Unknown Source) > at net.sourceforge.tess4j.Tesseract.getOCRText(Tesseract.java:433) > at net.sourceforge.tess4j.Tesseract.doOCR(Tesseract.java:288) > at net.sourceforge.tess4j.Tesseract.doOCR(Tesseract.java:209) > at net.sourceforge.tess4j.Tesseract.doOCR(Tesseract.java:193) > at com.ea.ocr.tesseract.ReadImageText.readText(ReadImageText.java:59) > at com.ea.ocr.tesseract.ReadImageText.main(ReadImageText.java:32) > Error opening data file ./eng.traineddata > Please make sure the TESSDATA_PREFIX environment variable is set to your > "tessdata" directory. > Failed loading language 'eng' > Tesseract couldn't load any languages! > -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
