It was working file but suddenly, i started receiving the error. I think, after 
installing Google App Engine . or depolying the App caused the error

What steps will reproduce the problem?
1. Install Linux Mint 15 
2. Install the SimpleCV superpack
3. Try to install the python-tesseract package

What is the expected output? What do you see instead?
When trying to install it say that the Dependency is not satisfiable: 
libopencv-core2.3

What version of the product are you using? On what operating system?
Trying to install the latest python-tesseract 0.8-1.5 for the i386 plataform, 
im using Linux Mint 15


The problem seems to be that the lastest libopencv-core2.4 is installed but the 
python-tesseract package don't accept.

I am also trying to install on ubuntu 10.10 amd64 which has python2.6 by 
default. 

I try both install python2.7 from source and apt-get install python2.7

But get the following error. 


dpkg: dependency problems prevent configuration of python-tesseract:
 python-tesseract depends on python (>= 2.7); however:
  Version of python on system is 2.6.6-2ubuntu2.
dpkg: error processing python-tesseract (--install):

Errors were encountered while processing:

What steps will reproduce the problem?

1. Installing python-tesseract-0.8-1.7_20130612_.macosx-10.8-x86_64 using the 
instructions from the wiki on an Mac OS X system that has opencv and tesseract 
(+ other dependencies) installed.

What is the expected output? What do you see instead?

Upon running a test file:

import cv2.cv as cv
import tesseract

api = tesseract.TessBaseAPI()
api.Init(".","eng",tesseract.OEM_DEFAULT)
api.SetPageSegMode(tesseract.PSM_AUTO)

image=cv.LoadImage("eurotext.jpg", cv.CV_LOAD_IMAGE_GRAYSCALE)
tesseract.SetCvImage(image)
text=api.GetUTF8Text()
conf=api.MeanTextConf()

The compiler produces an error indicating a missing method:
AttributeError: 'module' object has no attribute 'SetCvImage'

Therefore there's something wrong with the installation?

What version of the product are you using? On what operating system?

python-tesseract-0.8-1.7_20130612_.macosx-10.8-x86_64 on OS X 10.6.8 and Python 
2.7.5 with supposedly the correct dependencies installed.

$ tesseract --version
tesseract 3.02

  libgif 4.1.6 : libjpeg 8b : libpng 1.5.10 : libtiff 4.0.1 : zlib 1.2.7

Linux distro - 3.3.4-2-ARCH

Thanks for any suggestion.

What steps will reproduce the problem?
1. Perform OCR on the attached image with command line tesseract (tesseract 
3.png 3 && more 3.txt)
2. Perform OCR on the attached image with python-tesseract
3. Notice the errors thrown from python-tesseract 

What is the expected output? What do you see instead?
On certain images the results I'm seeing from python-tesseract are not exactly 
same as the results from command line tesseract on the same image. 
Additionally, some images (like the one installed) throw errors when 
python-tesseract performs OCR on them. Even though the result is same for this 
image from command line tesseract and python-tesseract. 

In my script this option returns False "print 
"HAVE_LIBLEPT=",tesseract.isLibLept()" I am assuming maybe this is why the 
results are different? 

What version of the product are you using? On what operating system?
$ tesseract --version
tesseract 3.02.02
 leptonica-1.69
  libjpeg 8d : libpng 1.5.14 : libtiff 4.0.3 : zlib 1.2.5

Please provide any additional information below.

I have searched google for this but have not found anything. My question is 
simply that should tesseract.isLibLept() be returning True for python-tesseract 
to return exactly the same results as the command line?

My script is like this:

api = tesseract.TessBaseAPI()
api.SetOutputName("outputName");
print "HAVE_LIBLEPT=",tesseract.isLibLept()
api.Init(".","eng",tesseract.OEM_DEFAULT)
api.SetPageSegMode(tesseract.PSM_AUTO)

hi,

I was wondering if you could provide me with some sort of documentation for 
this library.

Thanks.

What steps will reproduce the problem?
1. install the py-tesseract lib
2. copy the sample
3. run

What is the expected output? What do you see instead?
it works sometimes. but it crashed most times.
"A problem caused the program to stop working correctly. Please close the 
program."

What version of the product are you using? On what operating system?
python-tesseract-0.7.6.win32-py2.7.exe
my os is win vista.

Please provide any additional information below.

it seems an issue which related to memory leak.
did we make a clean up in the back ground?

code:

import tesseract

api = tesseract.TessBaseAPI()
api.Init(".", "eng", tesseract.OEM_DEFAULT)
api.SetVariable("tessedit_char_whitelist", "0123456789")
api.SetPageSegMode(tesseract.PSM_AUTO)
print tesseract.ProcessPagesWrapper('rand.png',api)

What steps will reproduce the problem?
1. Clone python-tesseract repository
2. python config.py
3. python setup.py build

I expect that C++ sources will be build, but instead what I see is:

include path=/usr/include
Current Version : 0.7

I am using Ubuntu 11.10, Python 2.7 and the last sources from the repository

As I found out it was because leptonica and tesseract headers were in 
/usr/local/include instead of /usr/include.
To fix this problem I made few changes to setup.py script and made a patch that 
fixed the problem.
I've attached patch to this issue.

On a clean Ubuntu install, follow the steps here doesn't work:
http://code.google.com/p/python-tesseract/wiki/HowToInstallPythonTesseractDeb

the error is:
 tesseract-ocr depends on leptonica; however:
  Package leptonica is not installed.


One option to fix is using the nutznboltz ppa that provides leptonica, but not 
for 11.10 oneiric and also the leptonica in oneiric itself is 1.68 already.

Workaround:
sudo apt-get install libleptonica
sudo dpkg -i --ignore-depends=leptonica /tmp/tesseract*.deb 
/tmp/python-tesseract_0.7-1.1_amd64.deb

This works just fine. Please change the dependency on leptonica to libleptonica.

I am running on a redhat system where I do no have admin priviledges or 
priviledges to write to /usr/local.  Instead, I have recreated the /usr 
directory structure under /foo/bar/usr where /foo/bar is a directory i have 
full rwx priviledges.  I had to build and install from source python 2.7.3 and 
swig 2.0.8 to the /foo/bar/usr.  Then I repeated these steps for tesseract and 
its dependencies.  Then after getting python-tesseract to build and install, I 
can't successfully import the tesseract module.  The output I get is:

The output I get is as follows:

>>> import tesseract
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "tesseract.py", line 26, in <module>

  File "tesseract.py", line 18, in swig_import_helper
    import _tesseract
ImportError: libtesseract.so.3: cannot open shared object file: No such file or 
directory

Here are the steps I followed:
1. mkdir /foo/bar/usr/local
2. set environment variables with
export CFLAGS=-I/foo/bar/usr/local/include; export 
LDFLAGS=-L/foo/bar/usr/local/lib; export 
LIBLEPT_HEADERSDIR=/foo/bar/usr/local/include
3. Compile and install jpeg-8d, giflib-4.1.6, libpng-1.5.13, tiff-4.0.0, 
zlib-1.2.7, and leptonica-1.69 using this command for each library:
./configure --prefix=/foo/bar/usr/local; make; make install;
4. install python 2.7.3 from source to /foo/bar/usr/local:
./configure --prefix=/foo/bar/usr/local; make; make install;
5. grab tesseract-ocr-read-only from svn compile and install:
./configure --prefix=/foo/bar/usr/local; make; make install;
6. copy tesseract-ocr-read-only/ccutil/tprintf.h to /foo/bar/usr/local/include
7. svn checkout http://python-tesseract.googlecode.com/svn/trunk 
python-tesseract
8. cd python-tesseract
9. modify lines 99 & 100:
incls = ['/usr/include', '/usr/local/include', '/foo/bar/usr/local/include']
libs=['/usr/lib', '/usr/local/lib', '/foo/bar/user-supported/usr/local/lib']
10. build and install python-tesseract running:
python config.py;
python setup.py clean;
python setup.py build;
python setup.py install --prefix=/foo/bar/usr/local

11. Enter python prompt and import tesseract.

The output I get is as follows:

main_dummy.cpp:45: error: 'class tesseract::TessBaseAPI' has no member named 
'ProcessPages'

What did I do wrong?


What version of the product are you using? On what operating system?

tesseract 3.0, svn checkout python-tesseract 24.6.2011

Is there a Mailinglist that I missed? Any connections to pytesser?

Hi,

I generated docstrings from latest tesseract "baseapi.h" in tesseract.py

I attached "baseapi.xml" file regexed from "baseapi.h" and "tesseract.py" with 
docstrings.

Line endings are '\r\n' if anyone is concerned.


Cheers

[deleted issue]

Steps to reproduce:
1. Install Python 2.7.3 on Windows 7 x64
2. Install python-tesseract-0.7.4.win32-py2.7.exe (as administrator)
3. Start python shell and `import tesseract`

The command line returns:
>>> import tesseract
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python27\lib\site-packages\tesseract.py", line 26, in <module>
    _tesseract = swig_import_helper()
  File "C:\Python27\lib\site-packages\tesseract.py", line 22, in swig_import_hel
per
    _mod = imp.load_module('_tesseract', fp, pathname, description)
ImportError: DLL load failed: The specified module could not be found.

I thought that the windows package is supposed to include a build of tesseract. 
 I haven't been able to find a tesseract.dll on my PC after installation, but 
may be looking for the wrong thing.

What steps will reproduce the problem?
1.Install winpython, tesseract, opencv, and pyhon-tesseract
2.Launch Spyder
3.Execute examples 1,2, or 3. 

What is the expected output? What do you see instead?

crashes at "result = tesseract.ProcessPagesBuffer(mBuffer,len(mBuffer),api)"
or
"tesseract.SetCvImage(image,api)"


What version of the product are you using? On what operating system?
Windows 7 64bit
python-tesseract_0.8-1.7.win32-py2.7.exe
tesseract-ocr-3.02.02

Spyder 2.2.0 internal shell on Python 2.7.5 32bits [Windows]
in both interpreters 
Python 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit (Intel)] on 
win32 
and
IPython 0.13.2

Please provide any additional information below.
I have tried as many combinations of settings as I could think of to avoid the 
suggested crash without setting "compatible to windows 7" and unbuffered "-u" 
flag.

I have set for python.exe and pythonw.exe in 
"C:\WinPython-32bit-2.7.5.0\python-2.7.5" compatible to windows 7 and XP 
Service Pack 3, also for Spyder.exe

I have edited to python.bat include "-u". I have tried the same for spyder.bat 
but spyder will hang on start.

I have added an environmental variable PYTHONUNBUFFERED

I have tried unbuffered calls suggested at 
http://stackoverflow.com/questions/881696/unbuffered-stdout-in-python-as-in-pyth
on-u-from-within-the-program

In terms of developing an app, I desperately need a solution that I can use 
from the interpreter. Has anyone got this running?

What steps will reproduce the problem?
1. install tesseract and python-tesseract from source (static build)
2. start python interpeter
3. import tesseract

What is the expected output? What do you see instead?
expected: the import of (python-)tesseract

What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?
Ubuntu 11.10 64bit, Tesseract 3.0.1, python-tesseract 6.1

Please provide any additional information below.

I build tesseract-ocr from google (http://code.google.com/p/tesseract-ocr). 
tesseract is working (I followed their installation instruction though from 
http://code.google.com/p/tesseract-ocr/wiki/ReadMe). When I try to build 
python-tesseract:

python setup.py build

I got: 
g++ -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions -Wl,-Bsymbolic-functions 
build/temp.linux-x86_64-2.7/tesseract_wrap.o 
build/temp.linux-x86_64-2.7/main_dummy.o -ltesseract_api -o 
build/lib.linux-x86_64-2.7/_tesseract.so
/usr/bin/ld: cannot find -ltesseract_api
collect2: ld returned 1 exit status
error: command 'g++' failed with exit status 1

Command "ls -al /usr/lib | greb tesseract_api" though can find it:
lrwxrwxrwx   1 root root           25 2011-09-12 05:47 libtesseract_api.so -> 
libtesseract_api.so.3.0.1

However, command "ldd /usr/lib/libtesseract_api.so" shows
ldd: /usr/lib/libtesseract_api.so: No such file or directory


I also tried to used deb package for 11.04 build I got:
dpkg: dependency problems prevent configuration of python-tesseract:
 python-tesseract depends on leptonica; however:
  Package leptonica is not installed.

Even though I have installed libleptonica (version 1.68-4 - does the lib prefix 
makes a difference?), libleptonica-dev and leptonica-progs

Same as the summary

What steps will reproduce the problem?
1. Fresh install of python 2.7
2. install using win32 installer
3. install numpy using win32 installer
4. attempt to run sample code
5. failure to open ./tessdata/eng.traineddata
6. Attempt to locate tessdata folder
7. unable to find tessdata folder

What is the expected output? What do you see instead?
Leaving aside that the installer does not list any dependencies on numpy, it is 
incomplete as it does not include enough components to run "out of the box". 

This may just be a documentation issue.

What version of the product are you using? On what operating system?
Python 2.7.1 win32
python tesseract 0.7.5

Please provide any additional information below.
I eventually found tessdata inside the tess-slim download. It's apparently 
something the tesseract-ocr looks for, which should be stated in the 
documentation.

Hi,

I impoved your scripts to be more flexible (search in /usr and usr/local for 
tesseract and leptonica, search for python 2.6, 2.7, 3.0, 3.1, 3.2).

patch was created with "svn diff".

I install leptonica from source.

http://www.leptonica.org/download.html

When I try : python setup.py build

I got the following error. 

/usr/bin/ld: cannot find -ltesseract_api

How do I export ?

Please help me.

The issue claims it is fixed in 3.01

Is there an indication when 3.01 will be available in the repository at  
ppa:nutznboltz/tesseract ?

Regards,
Gert-Jan Braas

Control characters are inserted into the document, and XML parsers cannot 
handle it without first trying to strip them out. This problem was reportedly 
fixed in the main tesseract SVN a few days ago, and I think producing an update 
linked with SVN will fix it.

Using Python 2.7.3 under Windows 7 X64.

P.S. Are there any instructions for building from SVN with VS 2008? I see the 
binary under downloads but there's no information as for how it was generated. 
Just libtesseract et al wrapped with swig?

Installed both tesseract deb packages then python wrapper (all 32bit) on Ubuntu 
11.04:

>>> import tesseract
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/pymodules/python2.7/tesseract.py", line 25, in <module>

    _mod = imp.load_module('_tesseract', fp, pathname, description)
ImportError: /usr/lib/pymodules/python2.7/_tesseract.so: undefined symbol: 
kPolyBlockNames

What steps will reproduce the problem?
1. Process a bunch of images.
2. Suddenly:
> Empty Page!!
> Segmentation Fault (core dumped)

Happens pretty randomly, I would guess 1/200 probability. Images get processed 
just fine on retry.


What is the expected output? What do you see instead?
It would be great if I just got a Python exception and could retry processing. 
Instead the whole program crashes and I have to start from beginning.

What version of the product are you using? On what operating system?
I'm using: python-tesseract_0.8-1.6_amd64.deb

What steps will reproduce the problem?
1. installed python-tesseract 0.7.6 win32 bundled with tesseract (Aug 14 
release) on Win XP with Python 2.7.  
2. Initially had DLL load problems but fixed them by moving the files mentioned 
here: http://code.google.com/p/python-tesseract/issues/detail?id=31
3. run either example script and python crashes with no error message.  (first 
example crashes on tesseract.ProcessPageBuffer and second example crashes on 
GetUTF8Text).

What is the expected output? What do you see instead?
Expect some kind of OCR output or even an error message.  Instead python 
crashes.  

Please provide any additional information below.
Stepping through in the debugger seems to put the source of the fatal error in 
_tesseract.pyd

Could you be so kind to write couple of lines how to compile this thing?

Making only 64bit debs is silly

==========
swig -python -c++ -I/usr/include/tesseract/ -I/usr/include 
-I/usr/include/leptonica -o tesseract_wrap.cpp tesseract.i
----------

You could check "/usr/local/include/" also

I'm using trunk. I wish to iterate through the document by paragraph, and the 
Tesseract GetIteration function expects a single argument: the document "level" 
(word, paragraph, block, etc..) However, python-tesseract does not expect/allow 
any parameters for api.GetIterator, and there are no examples of iteration that 
might explain how to accomplish this.

Additionally, I have searched the sourcecode for "PageIteratorLevel" (the enum 
type for the document levels), "RIL_PARA" (the specific level that I'm 
interested in), as well as "GetIterator" itself, but nothing that I found 
seemed useful.

For our project we need to combine OpenCV library and tesseract python 
bindings. So it seems more effective to set OpenCV image directly to tesseract 
instead of storing it into a file and let tesseract re-read it. 

Would it be possible to integrate following changes (included in the enclosed 
patch, the diff is made towards revision 95) into the python-tesseract project? 
I tested the patched changes under Ubuntu 11.04.

I also find out that shared tesseract library no longer names tesseract_api, so 
I also edited setup.py.

What steps will reproduce the problem?
1. Each of the 3 examples listed in Project Home result in IDLE crashing and 
requiring a shell restart
2. The error can be attributed to calls of the form tesseract.XXXX(*args,api) 
where api = tesseract.TessBaseAPI()

What is the expected output? What do you see instead?
Following the examples, I should see either the text output of the image 
supplied or the confidence values from the OCR algorithms.  Instead, I see the 
crash popup pictured in the attachment.

What version of the product are you using? On what operating system?
Using Python 2.7 on Windows XP (SP3).  This issue has occurred with both 
version 0.7.5 and 0.8-1.6

Please provide any additional information below.
When I remove the aforementioned calls, the test programs run (without expected 
output of course).

What steps will reproduce the problem?
1. Successfully Installed tesseract, python-tessearact, numpy, opencv
2. I am trying to run the code in Example2

What is the expected output? What do you see instead?
I ran the example for the attached sample file. The code is running smoothly 
but throwing appcrash error after exiting from the interpreter or after the 
execution of the python from the command line.

I digged a lil bit and found api.End() will actually produce the app crash.

What version of the product are you using? On what operating system?
Windows Server 2008
tesseract-ocr-setup-3.02.02.exe

Please provide any additional information below.

Can you please help me out with this issue

Hi All,

        I am an open source software developer from Sri Lanka...
Now a days i am developing a Free and Open source Check Scanner Software for 
Ubuntu...
For that i need to configure Python-Tesseract on Ubuntu 11.10...
I tried so meny time to do it , But it giving an error like "leptonic 
dependancy is not satisfied" ...
But i alredy installed leptonica 1.67 ... but still giving the same error...

i think the problem in the debian package...

So please help me guys regarding this...


Operating system: Ubuntu 11.10

Hi,

I installed python-tesseract on my CentOS 5.4 server following the wiki:
http://code.google.com/p/python-tesseract/wiki/HowToCompilePythonTesseractForCen
tos

When I tried to run 'test.py', the first two tests successed. However, the 
third test, 'ProcessPagesRaw', failed printing this message:

Test ProcessPagesRaw
Error in findFileFormatStream: truncated file
Error in pixReadStream: Unknown format: no pix returned
Error in pixGetDimensions: pix not defined
Error in pixGetColormap: pix not defined
Error in pixClone: pixs not defined
Error in pixGetDepth: pix not defined
Error in pixGetWpl: pix not defined
Error in pixGetYRes: pix not defined
Please call SetImage before attempting recognition.

When I tried to call 'ProcessPagesBuffer' in my python project, it gives the 
same error too. I think it's related to leptonica but I can't find the solution 
after almost one day straight down googling.

Now I am totally stuck. Please, any help would be greatly appreciated. Or are 
there ways to get around using 'ProcessPagesWraper' or 
'ProcessPagesFileStream', the first two functions called by 'test.py' which 
succeeded? Basically I need to parse an image from URL without saving it to the 
local drive, and the image format varies.

My setup:
CentOS 5.4, Python 2.6, leptonica 1.69, OpenCV 2.4.2.

Package liblept3 is not installed

The problem:

Please call SetImage before attempting recognition.Segmentation fault

From your example, 
api.SetOutputName("outputName");

What is the purpose of this SetOutputName?

What steps will reproduce the problem?
1. Install python-tesseract using the Homebrws instructions
2. Run example 2 in the homepage


What is the expected output? What do you see instead?

Python crashes. This is the full report 
https://gist.github.com/giacecco/6371150 .


What version of the product are you using? On what operating system?

Everything latest at the moment of writing, clean install of Homebrew and 
python-tesseract.


Please provide any additional information below.

Hi there,

Here's a small patch that I think could be a nice addition.
It exposes tesseract's iterators to python, allowing to finer use of the result 
data.

To apply:
patch -p1 < tesseract.patch

Let me know if you have any issues :)


PS: please move to github ??? :)

What steps will reproduce the problem?
1. Attempt to build python-tesseract from trunk using instructions in wiki on 
Ubuntu 11.10 AMD64

What is the expected output? What do you see instead?

I hope you can help, i didn't want to send a ticket cause I am guessing it's a 
pretty specific problem but i am going crazy with this setup right now so i 
need some help -and no, changing OS is not an option sadly)
