Tesseract OCR Python错误

Question

I am trying to install tesseract but if i follow all the steps I still get an error.

Traceback (most recent call last):
  File "C:\Users\julian\Documents\Schikka\tesseract.py", line 3, in <module>
    print(pytesseract.image_to_string(Image.open('images/test.jpg')))

    startupinfo)
FileNotFoundError: [WinError 2]  the system cannot find the file specified. 

I have tried to install it on linux as well and I still get an error code.

I currently have python 3.6

this is the code I tried:

from PIL import Image
import pytesseract
print(pytesseract.image_to_string(Image.open('images/test.jpg')))

please help me.

Seems you haven't installed tesseract and/or configured the paths incorrectly. You may try below steps.

1. Download and install tesseract 4.0 alpha for 64-bit windows from here .
2. Add C:\\Program Files\\Tesseract 4.0.0 to Windows environment variable PATH .
3. Set Windows environment variable TESSDATA_PREFIX to C:\\Program Files\\Tesseract 4.0.0\\tessdata .
4. Type tesseract -v in command prompt to verify if it works properly. Suppose the tesseract version information will return.

Take note that the paths above is an example. You need to set it as to your actual program installation path.

Then you may modify your pytesseract command as below to try again.

ocr = pytesseract.image_to_string(image, lang='eng', boxes=False, \
        config='--psm 10 --oem 3 -c tessedit_char_whitelist=0123456789')

Hope this help.
