tessdata folder not found at

Asked by elifcan çakmak

Hello,

I have the same question as many others. When I tried to extract a text it gives me the following error:

[error] TextRecognizer: init: tessdata folder not found at
[error] Region.text: text recognition is now switched off

Even after I tried every possible solution I still get the error. For example I tried to use

Settings.OcrDataPath = "your tessdata folder path"

tessdata folder exists in my path but it still says it doesn't.

Here is my code:

Settings.OcrDataPath = '/home/elifcan/downloads/libs'
Settings.OcrTextRead = True
Settings.OcrTextSearch = True
r=(Region(533,488,74,19))
id = r.text()
print id

here is the error: TextRecognizer: init: tessdata folder not found at /home/elifcan/downloads/libs/

Hey,

I don't know which solutions you have tried so far, but it is a known issue that in SikuliX 1.0.1, if you enable the OCR functionality, you need to rebuild the libs folder, so my recommendation if you haven't already done so, is to delete the contents of the libs folder, then launch the IDE again, and it will rebuild the libraries with the correct tessdata and you should be all set.

I figured that would be the case.
I assume you also have linked everything correctly so that the environment variables all work?
ex:
"
echo export LD_LIBRARY_PATH=/usr/local/lib >> /etc/profile
echo export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig >> /etc/profile
echo export TESSDATA_PREFIX=/home/<username>/Downloads/tesseract-ocr >> /etc/profile

# To set for current session
export LD_LIBRARY_PATH=/usr/local/lib
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
export TESSDATA_PREFIX=/home/<username>/Downloads/tesseract-ocr

ldconfig -v
"
