pytesseract Failed loading language \'eng\'

问题

I've seen a lot of other people getting this error, and I've tried a lot of different things to fix it. Nothing so far has worked. I have:

• Added the path to my Tesseract-OCR folder AND the tesseract.exe file to PATH
• Added an environment variable called TESSDATA_PREFIX which leads to the Tesseract-OCR folder
• Replaced the eng.traneddata file a couple times
• Added pytesseract.pytesseract.tesseract_cmd = r"C:\Program Files (x86)\Tesseract-OCR\tesseract.exe" to the program
• Tried running JUST the quickstart file instead of the program I'm running it in

and nothing has changed the error. At this point, I'm just looking for anything. The full error is as follows.

  File "pytesseract should work please.py", line 12, in <module>
    print(pytesseract.image_to_string(Image.open('text.png')))
  File "C:\Users\matth\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pytesseract\pytesseract.py", line 309, in image_to_string

回答1:

I fixed this issue by fully uninstalling pytesseract and installing an older version (3.2? I think..). So far I haven't noticed any functionality loss. I'm personally just happy that it works.
