Pytesseract : "TesseractNotFound Error: tesseract is not installed or it's not in your path", how do I fix this?

I see steps are scattered in different answers. Based on my recent experience with this pytesseract error on Windows, writing different steps in sequence to make it easier to resolve the error:

1. Install tesseract using windows installer available at: https://github.com/UB-Mannheim/tesseract/wiki

2. Note the tesseract path from the installation. Default installation path at the time of this edit was: C:\Users\USER\AppData\Local\Tesseract-OCR. It may change so please check the installation path.

3. pip install pytesseract

4. Set the tesseract path in the script before calling image_to_string:

pytesseract.pytesseract.tesseract_cmd = r'C:\Users\USER\AppData\Local\Tesseract-OCR\tesseract.exe'

First you should install binary:

On Linux

sudo apt-get updatesudo apt-get install libleptonica-dev sudo apt-get install tesseract-ocr tesseract-ocr-devsudo apt-get 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.

Then you should install python package using pip:

pip install tesseractpip install tesseract-ocr
