@tonydeng
you can download chi_sim or other languages from https://github.com/tesseract-ocr/tessdata
to your /usr/local/Cellar/tesseract/3.04.01_2/share/tessdata

from tess4j.

Hey there!

3.04 is currently not supported, please use one of the latest release, more info at the release page.

To get it running under Linux it's very easy, although I have a Mac, I'd never have tried tess4j on a macosx.

I will give it a try and get back to you.
Please post the information if you find out more.

Best regards,
OJ

eng is ok.

also, i clone the tess4j project from github. and update junit test to set language chi_sim, put chi_sim.traineddata to src/main/resources, It appeared the same problem.

@4F2E4A2E OK, Thank you，I will try it use tesseract 3.03.00 on Ubuntu.

from tess4j.

No need to use Ubuntu, because Tess4J works under OS X as well (at least under 10.10 - Yosemite). You do need to use the current release together with Tesseract 3.03 though.

from tess4j.

Good to know! :)
Did you install tesseract via brew?

from tess4j.

No, I built it from source because (at the time?) version 3.03 was not available in the Homebrew repo.

from tess4j.

Nice thanks.

from tess4j.

@4F2E4A2E hello,i have the same error.Did you solve this error?

from tess4j.

There was no error, only the datapath beeing not loaded correctly. Tell me more and i may be able to help you :)

Tess4j 1.5? Really? Why don't you use the latest version?

@4F2E4A2E I found the information in the sourceforege (http://tess4j.sourceforge.net/changelog.html) i think about Tess4j 1.5 is supported for Tesseract 3.02. i try the latest version ,thank you!

from tess4j.

@4F2E4A2E i got the same issue under Mac OS
tesseract, tesseract-eng and tesseract-chi-sim are all installed by port, the version of tesseract is 3.04.00_3

the error messages are:

Failed loading language 'chi_sim'
Tesseract couldn't load any languages!

but if i switch the language back to "eng", it worked fine ...

the libraries i used are:

<dependency>
<groupId>net.sourceforge.tess4j</groupId>
    <artifactId>tess4j</artifactId>
        <version>3.2.1</version>
</dependency>

    <groupId>net.java.dev.jna</groupId>
    <artifactId>jna</artifactId>
    <version>4.1.0</version>
</dependency>

could u pls help to have a look ?

from tess4j.

@fivesmallq @DavyLin have u solved that issue?

from tess4j.

@aceyin use tesseract 3.04.01dev with tess4j-3.2.0 maybe solve this issue.

➜ ~ tesseract -v
tesseract 3.04.01dev
leptonica-1.72
libjpeg 8d : libpng 1.6.20 : libtiff 4.0.6 : zlib 1.2.5

from tess4j.

@fivesmallq i'am using tesseract 3.04, and this issue occurred in 3.04 also ...
trying run the demo on ubuntu .

from tess4j.

@aceyin

maven:

        <dependency>
            <groupId>net.sourceforge.tess4j</groupId>
            <artifactId>tess4j</artifactId>
            <version>2.0.1</version>
        </dependency>

➜ ~ tesseract -v
tesseract 3.04.01dev
leptonica-1.72
libjpeg 8d : libpng 1.6.20 : libtiff 4.0.6 : zlib 1.2.5

test again. tess4j 3.2.1 is also works well.

from tess4j.

Hi guys! Did you for sure add and double checked that the lang-pack is in the correct by you define datafolder?

from tess4j.

@fivesmallq @4F2E4A2E
thanks guys, but it didnot work under my Mac...
here are the tesseract version and lang package

from tess4j.

Maybe you are using the wrong language pack files? https://github.com/tesseract-ocr/langdata/tree/master/chi_sim
If it is working with the english language pack, then it should work with the rest

from tess4j.

@4F2E4A2E @fivesmallq
i tried run tesseract from command line, and it worked.

so i think the problem should be something like path or classpath etc.

from tess4j.

Can you confirm if english langpack is working?

from tess4j.

@aceyin ?

from tess4j.

@aceyin
I was the same question, would you like to ask you now to solve it?

from tess4j.

It also not work for me on macOS 10.12.3

Tess4j latest version.

<dependency>
    <groupId>net.sourceforge.tess4j</groupId>
    <artifactId>tess4j</artifactId>
    <version>3.2.1</version>
</dependency>

I did install tesseract-ocr frow brew. Latest version: 3.04.01_2

brew install tesseract --all-languages

Tesseract instance = new Tesseract();
instance.setDatapath("/usr/local/Cellar/tesseract/3.04.01_2/share/tessdata");
instance.setLanguage("jpn");

Error:

Failed loading language 'jpn'
Tesseract couldn't load any languages!

from tess4j.

Try with JNA 4.3.0 to see if it makes any difference.

And the path should be set the parent directory of tessdata directory:

instance.setDatapath("/usr/local/Cellar/tesseract/3.04.01_2/share/");

from tess4j.

Thanks Quan Nguyen for your response.
You mean I just need add this repository into Maven?

<dependency>
    <groupId>net.java.dev.jna</groupId>
    <artifactId>jna</artifactId>
    <version>4.3.0</version>
</dependency>

<dependency>
    <groupId>net.sourceforge.tess4j</groupId>
    <artifactId>tess4j</artifactId>
    <version>3.2.1</version>
</dependency>

And I also change path into

ITesseract instance = new Tesseract(); // JNA Interface Mapping
instance.setDatapath("/usr/local/Cellar/tesseract/3.04.01_2/share");
instance.setLanguage("jpn");

It also throws that error message.

hs_err_pid59284.log.zip

PS: instance.setLanguage("eng"); works fine for me

from tess4j.

Yes. Can you try temporarily removing eng.traineddata file and renaming jpn.traineddata to that and see if that would work?

It is really a shot in the dark since we do not have Mac to investigate the issue. The library has been tested on Windows and Linux. JNA is the only piece that is different between the platforms since it has native components specific to an OS, so we think tracing through JNA code in debugging could help.

from tess4j.

Thanks for your reply.
But, It still throws that error message, though I rename jpn package to eng.
I think problem derived from jpn package.
It's a pity if you can't check on macOS environment.
I suggest you use Hackintosh in your PC.
hs_err_pid86067.log.zip

from tess4j.

Someone commented in #34 that "All language data larger than about 20-25 MB cannot be loaded."

from tess4j.

Could you fix it in next version :D

from tess4j.

Make sure the environment variable TESSDATA_PREFIX is set to your tessdata directory!
(for ex. C:\msys64\mingw32\share\tessdata).
