How do I resolve a TesseractNotFoundError?

Question

I am trying to use pytesseract in Python but I always end up with the following error:

    raise TesseractNotFoundError()
pytesseract.pytesseract.TesseractNo         


        

Answer 1

I got this error because I installed pytesseract with pip but forget to install the binary.

On Linux

sudo apt update
sudo apt install tesseract-ocr
sudo apt install libtesseract-dev

On Mac

brew install tesseract

On Windows

download binary from https://github.com/UB-Mannheim/tesseract/wiki. then add pytesseract.pytesseract.tesseract_cmd = 'C:\\Program Files (x86)\\Tesseract-OCR\\tesseract.exe' to your script. (replace path of tesseract binary if necessary)
