Fix TesseractError eng.traineddata Please make sure the TESSDATA_PREFIX environment variable - Python Tutorial

The simplest way is to set tessdata_dir_config.

For example:

from  PIL import  Image
import pytesseract
tessdata_dir_config = '--tessdata-dir "C:\\Program Files (x86)\\Tesseract-OCR\\tessdata"'
img_path='screenshot.png'
text=pytesseract.image_to_string(Image.open(img_path), config=tessdata_dir_config)
 
print(text)

C:\\Program Files (x86)\\Tesseract-OCR\\tessdata is the directory of Tesseract-OCR tessdata.

Run this code, you will find this error is fixed.
