What is the path to your tessdata folder, which should already have the .traineddata files?

eshvan · 2016-04-25T17:20:03Z

same as commented line.
"/usr/local/Cellar/tesseract/3.04.01_1/share/'

nguyenq · 2016-04-26T00:32:48Z

Can you load any other language, for instance, eng?

eshvan · 2016-04-26T06:53:02Z

Yes any other lang works fine.Seems problem with two chi_tra and chi_sim

nguyenq · 2016-04-26T11:25:47Z

So the problem is with specific .traineddata files. They might have been corrupted during download. I do not have any issue with the copy I currently have.

eshvan · 2016-04-26T12:42:58Z

Re-download traineddata from https://github.com/tesseract-ocr/tessdata didn't help
Checked again it fails with all large traineddata files, more ~20mb
It works from console if i simply run
tesseract imagefile output -l chi_tra
And it works on windows machine
Any suggestions ?

nguyenq · 2016-04-26T23:55:11Z

I just tested using the latest chi_*.traineddata versions with VietOCR and had no problems. The program ran with -Xms128m -Xmx1024m option. Since those data files are large, you may want to give more memory to your program.

4F2E4A2E · 2016-04-27T06:50:08Z

@eshvan is the problem solved now?

eshvan · 2016-04-28T07:27:47Z

nope still no luck.
i tried to assign -Xms128m -Xmx1024m for Java Runtime Environment didn't help. I use intellij idea to run code it has same settings.

nguyenq · 2016-04-29T00:36:45Z

We still can't reproduce your issue. Tess4J unit tests would run on Windows 10 with no problem. We don't have a Mac to try on. Can you try executing the unit tests from the console?

dong77 · 2016-05-02T12:46:44Z

I ran into the very same problem on my mac - cannot load 'chi_sim' at all.

This issue seems just like #26. I came across the same problem under OSX 10.11(tesseract 3.04). All language data larger than about 20-25 MB cannot be loaded. However, it works well under Ubuntu 16.04, tesseract 3.03.

I have tried run tesseract(3.04, OSX 10.11) as a C++ lib directly and it works well.Is it possible that this issue is caused by JNA? I have tried -Xms128m -Xmx1024m but it has no effect.
Has anyone tried an old version of tesseract (<=3.03) under OSX?

tonydeng · 2016-07-27T15:56:05Z

@dracupid
Seemingly completely tess4j problem, the direct implementation of the Tesseract command is no problem

nguyenq · 2016-07-28T22:35:48Z

@dracupid, I suspect something with JNA as well because that, beside Tesseract binary, is the piece that has platform-specific components. Tess4J works fine with any language data on Windows and Linux. We do not have a OS X system to perform testing on, so that would depend on the users to carry out.

I suggest that you download JNA source and step through it for debugging the issue. Hope that would be the source of the problem, or the investigation may even require stepping into native codes of Tesseract.

How about trying out this before looking into JNA? Play with "eng" first. Once you got the program to work, rename the .traineddata file that you have problem with as eng.traineddata and run the program again. Do not try on a PDF -- stay with a simple image.

smartlan · 2016-12-05T09:54:14Z

seems it can not load chi_sim data in OS X system !!!!

dongqiangqiang · 2017-03-08T02:33:07Z

I also have the problem,and I downoad the chi_sim.traineddata, but the problem is also show

vitasoft · 2017-03-16T17:46:53Z

I'm using tess4j 3.3.0 on Mac with Java8

"kor.traineddata" have the same problem!

Failed loading language 'kor'

Eng,Spa and other western language work well.

But in case of east asian language don't work.

"kor", "chi_sim", "chi_tra" don't work

This issue is only Mac user's problem?

Is there anybody find a solution?

for reference, Tesseract command works well in every languages

nuclearg · 2017-07-22T14:08:07Z

Now I meet the same problem... On OSX, there is only a simple message:

Failed loading language 'chi_sim'

and tesseract command works very well.

Any one can help?

Mao-x-w · 2018-01-10T16:28:36Z

I had met the same problem in mac if the problem was solved, please tell me

justinchuntingho · 2018-01-13T20:10:16Z

I have the same problem too.

NoobDoesMC · 2018-01-14T01:29:51Z

I get this error

nguyenq · 2018-01-14T04:23:37Z

It may be related to Tesseract issue #1250.

delonzhou · 2018-06-05T03:36:34Z

i have the same issue too.

nguyenq · 2018-08-05T00:38:37Z

Did anyone try out with changing locale, as suggested in Tesseract issue?

export LC_ALL=C

hyunseo0404 · 2018-08-24T15:35:44Z

Just tried setting LC_CTYPE env variable to C (LC_CTYPE=C) and it worked!
I've tried all of the above mentioned language data (kor, chi_sim, chi_tra) and they now all seem to work fine after changing the locale.

I suggest everyone else having this problem to try this as well.

parmarmanoj007 · 2018-08-29T09:25:58Z

get location of ur tessdata folder by typing in command prompt:
$ brew list tesseract
in may case:

now
tessdata_dir_config = r'--tessdata-dir "/usr/local/Cellar/tesseract/3.05.01/share/tessdata"'

txt= image_to_string(img,lang='eng',config=tessdata_dir_config)

zcaudate · 2019-03-27T13:44:45Z

Can someone explain why export LC_CTYPE=C works? In the issue, someone also mentioned that there may be potentially messy outcomes in java and python. Does anyone know what that might be?

4F2E4A2E · 2019-04-09T19:30:42Z

This is the best explanation I've found so far: https://www.gnu.org/software/libc/manual/html_node/Locale-Categories.html

iseegr8tfuldeadppl · 2019-05-06T00:06:27Z

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

nguyenq · 2019-07-26T02:33:06Z

According to tesseract-ocr/tesseract#1250, the problem has been resolved in Tesseract 4.1.0 for macOS. Can someone verify with Tess4J 4.4.0?

lokesh-stack · 2019-09-09T06:10:03Z

can some one help me with following error:

lokesh@Biu:~$ tesseract /home/lokesh/Desktop/tess_imgs/1.tif ~/Desktop/out -l foo
Failed loading language 'foo'
Tesseract couldn't load any languages!

johnpili · 2019-09-14T14:43:45Z

@lokesh-stack I had similar problem too. I resolved it by downloading the raw tessdata.

https://github.com/tesseract-ocr/tessdata/blob/master/eng.traineddata?raw=true

can some one help me with following error:

lokesh@Biu:~$ tesseract /home/lokesh/Desktop/tess_imgs/1.tif ~/Desktop/out -l foo
Failed loading language 'foo'
Tesseract couldn't load any languages!
Could not initialize tesseract.

EliasPereirah · 2023-12-10T00:15:01Z

This happened to me, in my case I was downloading the data trained with curl, the problem is that I was downloading:
https://github.com/tesseract-ocr/tessdata_best/blob/main/example.traineddata
instead of:
https://github.com/tesseract-ocr/tessdata_best/raw/main/example.traineddata

just change /blob/ to /raw/ in the URL, can be the case for someone else
