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

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:\Users\cpcho\AppData\Local\Continuum\Anaconda3\lib\site-packages\pytesseract\pytesseract.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!

I faced the same problem. I tried all solutions on Google, without success. Finally, I solved the problem by replacing.

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

with 

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

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)

Day 1 -all works; Day 2 -this error; on second computer all works... 5 hours later: ===i find ANSWER in my mind===

From "C:\Program Files\Tesseract-OCR\tessdata" copy 'eng.traineddata' to "C:\Program Files\Tesseract-OCR"

its work =\
