Segfault in pixa_to_list
Hi, I've encountered a segfault in pixa_to_list and I can reproduce it consistently. I don't have any idea how to fix this though.
This image here will always make tesserocr segfault:
This image on the other hand works fine:
The code I'm using for testing is simple:
import tesserocr
from PIL import Image
import sys
print(tesserocr.tesseract_version())
print(tesserocr.get_languages())
png = Image.open(sys.argv[1]).convert('L')
# print(tesserocr.image_to_text(png))
with tesserocr.PyTessBaseAPI() as api:
api.SetImage(png)
boxes = api.GetComponentImages(tesserocr.RIL.WORD, True)
for _, box, _, _ in boxes:
pad = box['h'] * 0.2
api.SetRectangle(box['x']-pad, box['y']-pad, box['w']+pad, box['h']+pad)
text = api.GetUTF8Text().strip()
confidence=api.MeanTextConf()
print(text, confidence)Here is a crash report from OS X: crashreport.txt
Here is the output from a succesful run (including version numbers and so on): success.txt
I'm using tesseract 3.05.00 which I compiled myself as I had this problem with the 3.04 also and I thought maybe the new version would fix the issue.
Here are the relevant environment variables I used when I executed python setup.py install for tesserocr:
declare -x CFLAGS="-g -fno-omit-frame-pointer -UNDEBUG -O0"
declare -x CPPFLAGS="-I/Users/otimpe/dev/tesseract-3.05.00/dist/include"
declare -x DYLD_LIBRARY_PATH="/Users/otimpe/dev/tesseract-3.05.00/dist/lib"
declare -x LDFLAGS="-L/Users/otimpe/dev/tesseract-3.05.00/dist/lib -g"
declare -x TESSDATA_PREFIX="/usr/local/share"
Is any plan to porting tesseract 4.0 (alpha)
Is any plan to porting tesseract 4.0 alpha, 4.0 add new OCR engine based on LSTM neural networks is more powerful and fast (Hardware acceleration)
How to recognize single character
If i use a image with several characters, it works. How ever it does't work if i want to recognize single character. What should I do?
Thanks!
PDF support?
Could anybody provide an example of how to OCR a PDF?.
Thanks guys!
Crash in WordFontAttributes
WordFontAttributes can return a NULL pointer. This crashes the Python string conversion.
Resolved: Install fails because of TessPdfRenderer type mismatch
Never mind. Issue fixed by switching to tesseract4 branch
'tesserocr.PyPageIterator' object has no attribute 'GetUTF8Text'
Hello,
I'm iterating over RIL.BLOCK and want to get the text of each BLOCK.
In tesserocr.pyx line 390 the following is written:
>>> for e in iterate_level(api.AnalyseLayout(), RIL.WORD):
... word = e.GetUTF8Text()
Unfortunately this does not work. I get the following error:
AttributeError: 'tesserocr.PyPageIterator' object has no attribute 'GetUTF8Text'
build fails on freeBSD
appearently it does not find the leptonica headers which are in /usr/local/include for BSD systems. so i guess this might be a problem on OSX too.
with pip the issue can be worked around with setting CPPFLAGS:

Error while executing Python as a script
Hi guys,
I was just expermimenting around with the API and found something that I think is an issue.
Instead of executing a script, the API brings out a weird cursor(something shaped like a plus symbol) and freezes
Screenshot:
https://s13.postimg.org/ennhe0e1j/IMG_20170213_113348.jpg
Steps to replicate:
This is the script I wrote http://pastebin.com/JbFR7MaG
Instead of doing the normal python script.py to execute the script, I first made the script executable by doing chmod +x script.py .
I then executed the script by doing ./script.py image.png
The script doesn't execute after the import statement and stops with the + shaped cursor.
Is this an issue? Or am I doing something wrong?
Thanks,

It worked just fine in Ubuntu. Any idea what's wrong?
I thougt maybe it's a problem of gcc version, so I updated it to 5.4.0 but it didn't help.
Error while performing OCR on image
Hello,
I am using the following code in order to perform OCR on an image (attached):
from tesserocr import PyTessBaseAPI
from PIL import Image
DEFAULT_LANGUAGE = "spa"
filePath = "/home/jorge/Desktop/prueba_tess/c1.png"
if __name__ == '__main__':
img = Image.open(filePath)
tesseract = PyTessBaseAPI(lang=DEFAULT_LANGUAGE)
tesseract.SetImage(img)
tesseract.Recognize()
print tesseract.GetUTF8Text()
tesseract.End()but what I am getting with this particular image in console is the following:
start >= 0 && start + num <= length_:Error:Assert failed:in file ratngs.cpp, line 321
Here is what I am using
tesserocr 2.2.1
tesseract 3.04.01
leptonica-1.71
libjpeg 8d : libpng 1.2.50 : libtiff 4.0.3 : zlib 1.2.8
I think I have all correctly set up because I have extracted text from other images. but with this one throws that "error"...
Any help is appreciated.
Thanks in advance!

The problem seems to be in setup.py line 130 as that compares version which is comparing TESSERACT_VERSION which is 197633 at this point with 4. while it should probably compare with 0x40000.

When I perform the same operation using the PyTessBaseAPI , Iget the following bounding boxes:
The problem is that I need the relative position of the values, so that to extract a key to value inference, whle performing the same action for multiple documents, so i can not (and dont want to) manually interfere. I can not understand why 7 and 9 are not recognized. To add to this, I got a lot fewer results when I set the segmentation mode to AUTO (this result is given using SPARSE_TEXT). Is there a solution to this absurd problem or is it a matter of luck?

AttributeError: 'NoneType' object has no attribute 'Orientation'Segfault when tessdata are missing
If you do not have installed tessdata or TESSDATA_PREFIX is wrong, Python with tesserocr segfaults. I think it should rather fail with some error.
The command line tesseract handles this gracefully with error:
Error opening data file /invalid/tessdata/eng.traineddata
Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory.
Failed loading language 'eng'
Tesseract couldn't load any languages!
Could not initialize tesseract.
To reproduce this, just set environment variable TESSDATA_PREFIX to non existing directory.
Failed to install Tesserocr
Hi, i tried to install the Tesseract 4.0 on ubuntu as described on the website
all worked fine except for the the last command pip install tesserocr although i already have python 2.7 installed,
im attaching a snapshot of the error that i have when i run the above command
Any ideas on how to solve this issue?
Thanks
Python tesserocr image_to_text Runtime Error:failed to read picture
platform:Ubuntu 15.1/Python 2.7 This is a demo which I used,from https://github.com/sirfz/tesserocr
import tesserocr
from PIL import Image
print tesserocr.tesseract_version() # print tesseract-ocr version
print tesserocr.get_languages() # prints tessdata path and list of available languages
image = Image.open('03.jpg') # I verify the file and directory is right
print tesserocr.image_to_text(image) # print ocr text from image
# or
print tesserocr.file_to_text('03.jpg')
And above get these output:

Does it support white list
How could I add white list for the recognition please? For example, if I know my image contains digits only. How could I set to the result limit to [0-9]?
setup.py doesn't recognize tesseract 4 (the result of tesseract -v is printed in stdout)
In my tesseract installation (version 4.00), when i do tesseract -v the result is printed in the stdout, so the version in get_tesseract_version() in setup.py will be always equal to an empty string
A quick fix can be:
p = subprocess.Popen(['tesseract', '-v'], stderr=subprocess.PIPE, stdout=subprocess.PIPE)
stdout_version, version = p.communicate()
if version == '':
version = stdout_version
Segmentation fault on GetUTF8Text()
Hi.
Thanks for your previous messages.
I have just tested with your image file again.
Unfortunately, it says "Segmentation fault(core dumped)" after finding 12 textlines.
Error occured in ocrResult = api.GetUTF8Text() line.
Seems like I have not installed tesserocr properly.
I am eager to hear from you soon.
Thanks.

Hi, I am trying to install tesserocr on my Unbuntu x64 14.04.
Unfortunately, I failed to install tesserocr.
Here is the output:
ubuntu@ubuntu-MS:~/tmp/tesserocr$ sudo python setup.py build_ext -I/usr/local/include
running build_ext
Traceback (most recent call last):

raise Exception(error)
Exception: Package tesseract was not found in the pkg-config search path.
Perhaps you should add the directory containing `tesseract.pc'
to the PKG_CONFIG_PATH environment variable
No package 'tesseract' found
Any idea?
Restricting character set
Is it possible to restrict the character set which is recognized?
The tesseract project already has configuraton files for such things (see e.g. how-to-recognize-only-digits), but I wasn't able to figure out how to do this with this project.
Add support for PSM mode 0
I found some code on the forum and a blog that may help:
OSResults *orientationStruct = new OSResults();
bool gotOrientation = myTess->DetectOS(orientationStruct);
int bestOrientation = -1;
float bestOrientationScore = 0;
if ((gotOrientation) && (orientationStruct->orientations != NULL)) {
for (int i=0; i<4; i++) {
if (orientationStruct->orientations[i] > bestOrientationScore) {
bestOrientation = i;
bestOrientationScore = orientationStruct->orientations[i];
}
}
}
// This is the result we were asked for
results.textOrientation = bestOrientation; #include <tesseract/baseapi.h>
#include <tesseract/osdetect.h>
#include <leptonica/allheaders.h>
int main(int argc, char **argv) {
OSResults os_results;
tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
if (api->Init(NULL, "eng")) {
fprintf(stderr, "Could not initialize tesseract.\n");
exit(1);
}
Pix *image = pixRead(filename);
api->SetImage(image);
// To detect correct OS and flip images
api->DetectOS(&os_results);
OrientationDetector os_detector = OrientationDetector(&os_results);
int correct_orientation = os_detector.get_orientation();
// Had to add this condition because get_orientation result and
// pixRotateOrth were not in sync.
if (correct_orientation == 1) {
image = pixRotate90(image, -1);
}
else if (correct_orientation == 3) {
image = pixRotate90(image, 1);
}
else if (correct_orientation == 2) {
pixRotate180(image, image);
}
api->SetImage(image);
char* ocrResult = api->GetUTF8Text();
fprintf(stdout, "Recognized Text: %s\n", ocrResult);
api->End();
pixDestroy(&image);
delete [] ocrResult;
return 0;
}Cant install tesseocr with pip -r
Hi, I want to install tess with pip insatll -r requirements.txt (in running tests with tox actually), but this scenario doesnt work. See:
$ virtualenv test
$ cd test/
$ source bin/activate
(test) $ echo Cython >> requirements.txt
(test) $ echo tesserocr >> requirements.txt
(test) $ pip install -r requirements.txt
I got error:
Collecting Cython (from -r requirements.txt (line 1))
Using cached Cython-0.25.2-cp35-cp35m-manylinux1_x86_64.whl
Collecting tesserocr (from -r requirements.txt (line 2))

Complete output from command python setup.py egg_info:

ImportError: No module named 'Cython'
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-ag5vqu0y/tesserocr/
I'm Python newbie, but I think this issue maybe due to lack of setup_requires or install_requires in https://github.com/sirfz/tesserocr/blob/master/setup.py?
Cannot get text with French language
Hi !
I'm trying to use tesserocr with french language but I keep getting errors on Unicode decoder
api = PyTessBaseAPI(lang='fra')
api.SetImage(Image.open("20170509_182040.jpg"))
api.SetSourceResolution(300)
api.GetUTF8Text()
Returns:
Traceback (most recent call last):
File "", line 1, in
File "tesserocr.pyx", line 2033, in tesserocr.PyTessBaseAPI.GetUTF8Text (tesserocr.cpp:18137)

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc3 in position 341: invalid continuation byte
Although the english version is working:
api = PyTessBaseAPI()
api.SetImage(Image.open("20170509_182040.jpg"))
api.SetSourceResolution(300)
api.GetUTF8Text()
Returns :
'The text that I want'
This is my installation :
tesserocr.version
'2.1.3'
tesserocr.tesseract_version()
'tesseract 3.05.00\n leptonica-1.74.1\n libjpeg 8d : libpng 1.6.29 : libtiff 4.0.7 : zlib 1.2.8\n'
MacOS Sierra
Is it a known issue or do I need to change something to get it to work ?
Thanks for your help !
(Fixed): Segmentation Fault on import tesserocr
I successfully installed tesserocr using the tesseract4 branch.
This is the output of tesseract -v on my system (Ubuntu 14.04)
tesseract 4.00.00alpha
leptonica-1.74.1
libgif 4.1.6(?) : libjpeg 8d (libjpeg-turbo 1.3.0) : libpng 1.2.50 : libtiff 4.0.3 : zlib 1.2.8 : libwebp 0.4.0
Found AVX
Found SSE
tesserocr, tesseract and leptonica have been built from source.
I get a segmentation fault when I import tesserocr in python. Here is the entire core dump I obtained using gdb if it helps. Please let me know the steps I should take to fix this.

installation problem in python3
Hi, I'm trying to install tesserocr in a Docker container that's set up as follows:
FROM ubuntu:14.04
RUN apt-get -y update && apt-get install -y tesseract-ocr python3-imaging python3-pip python3-skimage libtesseract-dev libleptonica-dev
RUN pip3 install pytesseract ipython Cython
Then inside the container I manually run the command:
pip3 install tesserocr
It fails with the following. Any tips for how to get past this? Thanks.

Publish Wheels
Ideally with static libraries included so that all that is required for installation in pip.
Building on Windows
I have been working on making some bots for programs that only run in windows and I was wondering if you had any pointers on compiling on windows.
I was actually able to build tesserocr.lib but I cannot get past that step.
I used https://github.com/peirick/VS2015_Tesseract to build libtesseract and used that to satisfy all of the imports.
Thank you.
Python versions supported
It seems that only Python 2.7 is supported
https://pypi.python.org/pypi/tesserocr/2.0.0
Any plan to support Python 3.x in the near future?
I suggest you to add a paragraph to the README that declares which Python versions are supported.
Is this expected? PIL+image_to_text and file_to_text give different results
I ran the sample code thats in the readme text with one of my images and interestingly, it gives two different results when using PIL and then image_to_text rather than going directly with file_to_text. The PIL version seems to perform better, and the images are just regular JPEGs.
Sample code being referenced and output is below
CODE
import tesserocr
from PIL import Image
print tesserocr.tesseract_version() # print tesseract-ocr version
print tesserocr.get_languages() # prints tessdata path and list of available languages
image = Image.open(l.blobname)
print tesserocr.image_to_text(image) # print ocr text from image
print "==================================================================="
# or
print tesserocr.file_to_text(l.blobname)

SetCvImage
Is there a way to set OpenCV images directly like the one in Python Tesseract? Opencv always comes in handy for preprocessing and it would be a waste of resources to save it to a file and read it again
incorrectly detects orientation
I've noticed the orientation example doesn't distinguish between upside down/rightside up and clockwise/counter clockwise orientations.
reubano@tokpro [~]⚡ tesseract -psm 0 up.jpg -
Orientation: 0
Orientation in degrees: 0
Orientation confidence: 0.23

Script confidence: 0.98
reubano@tokpro [~]⚡ tesseract -psm 0 down.jpg -
Orientation: 2
Orientation in degrees: 180
Orientation confidence: 0.21
Script: 1
Script confidence: 0.61with PyTessBaseAPI(psm=PSM.AUTO_OSD) as api:
for path in ['up.jpg', 'down.jpg']:
image = Image.open(path)
api.SetImage(image)
api.Recognize()
it = api.AnalyseLayout()
print it.Orientation()
(0, 0, 2, 0.0)
(0, 0, 2, 0.0)getUtf8text can not recognize number and Upper letter
when i pass a image with letters and numbers to tesserocr,the result show that number and upper letter can not be recognize.
how can i fix this problem?
