Tesseract running error

Question

I have a problem with running tesseract-ocr engine on linux. I\'ve downloaded RUS language data and put it to tessdata directory (/usr/local/share/tessdata). When I\'m tryin

Answer 1

No previous solution worked for me.

I've installed both by apt-get and manually downloading the tessdata, moved around /usr and so on and no one worked even if i exported the variable thousand times.

Finally, on a last try before start to cry i've tried to pass the path directly to the instance of Tesseract().

In Python: tr = Tesseract("/usr/local/share/tesseract-ocr/") and now it works. To clarify, im using tesserwrap module.

Answer 2

I had this error too on the Windows machine.

My solution.

1) Download your language files from https://github.com/tesseract-ocr/tessdata/tree/3.04.00

For example, for eng, I downloaded all files with eng prefix.

2) Put them into tessdata directory inside of some folder. Add this folder into System Path variables as TESSDATA_PREFIX.

Result will be System env var: TESSDATA_PREFIX=D:/Java/OCR And OCR folder has tessdata with languages files.

This is a screenshot of the directory:

Answer 3

tessdata_dir_config = r'--tessdata-dir "/usr/local/Cellar/tesseract/4.1.1/share/tessdata"'
pytesseract.image_to_string(imgCrop,lang='eng',config=tessdata_dir_config)

Answer 4

You can grab eng.traineddata Github:

wget https://github.com/tesseract-ocr/tessdata/raw/master/eng.traineddata

Check https://github.com/tesseract-ocr/tessdata for a full list of trained language data.

When you grab the file(s), move them to the /usr/local/share/tessdata folder. Warning: some Linux distributions (such as openSUSE and Ubuntu) may be expecting it in /usr/share/tessdata instead.

# If you got the data from Google, unzip it first!
gunzip eng.traineddata.gz 
# Move the data
sudo mv -v eng.traineddata /usr/local/share/tessdata/

Answer 5

For Windows Users:

In Environment Variables, add a new variable in system variable with name "TESSDATA_PREFIX" and value is "C:\Program Files (x86)\Tesseract-OCR\tessdata"
