python - Pytesseract: Error opening data file \Program Files (x86)\Tesseract-OCR\en.traineddata

Question

I am trying to use pytesseract on Jupyter Notebook.

• Windows 10 x64
• Running Jupyter Notebook (Anaconda3, Python 3.6.1) with administrative privilege
• The work directory containing TIFF file is in different drive (Z:)

When I run the following code:

try:
    import Image
except ImportError:
    from PIL import Image
import pytesseract

pytesseract.pytesseract.tesseract_cmd = 'C:\Program Files (x86)\Tesseract-OCR\tesseract.exe'

tessdata_dir_config = '--tessdata-dir "C:\Program Files (x86)\Tesseract-OCR\tessdata"'

print(pytesseract.image_to_string(Image.open('Multi_page24bpp.tif'), lang='en', config = tessdata_dir_config))

I get the following error:

TesseractError                            Traceback (most recent call last)
<ipython-input-37-c1dcbc33cde4> in <module>()
     11 # tessdata_dir_config = '--tessdata-dir "C:\Program Files (x86)\Tesseract-OCR\tessdata"'
     12 
---> 13 print(pytesseract.image_to_string(Image.open('Multi_page24bpp.tif'), lang='en'))
     14 # print(pytesseract.image_to_string(Image.open('test-european.jpg'), lang='fra'))

C:UserscpchoAppDataLocalContinuumAnaconda3libsite-packagespytesseractpytesseract.py in image_to_string(image, lang, boxes, config)
    123         if status:
    124             errors = get_errors(error_string)
--> 125             raise TesseractError(status, errors)
    126         f = open(output_file_name, 'rb')
    127         try:

TesseractError: (1, 'Error opening data file \Program Files (x86)\Tesseract-OCR\en.traineddata')

I found these two references helpful but I am missing something: https://github.com/madmaze/pytesseract/issues/50 https://github.com/madmaze/pytesseract/issues/64

Thank you for your time on this!

If you don't want to set environment variable you can pass as an argument as well

For example:

First, do your imports

    import pytessetact
    from PIL import Image

And now configure pytesseract

    pytesseract.pytesseract.tesseract_cmd = "C:/path_to_your_tesseract.exe"
    tessdata_dir_config = '--tessdata-dir "C:/path_to_your_tessdata_folder"'

    pytesseract.image_to_string(image, config=tessdata_dir_config)
