Question

Answer 1

Under Windows 10 OS environment, the following method works for me:

1. https://github.com/tesseract-ocr/tesseract/wiki Download tesseract and install it. Windows version is available here: https://github.com/UB-Mannheim/tesseract/wiki

2. Find script file pytesseract.py from C:\Users\User\Anaconda3\Lib\site-packages\pytesseract and open it. Change the following code from tesseract_cmd = 'tesseract' to: tesseract_cmd = 'D:/Program Files (x86)/Tesseract-OCR/tesseract.exe'

3. You may also need add environment variable D:/Program Files (x86)/Tesseract-OCR/

Hope it works for you!

Answer 2

The following three commands will do the needful :

sudo apt update
# This will update your packages
sudo apt install tesseract-ocr
# This will install OCR
sudo apt install libtesseract-dev
# This will add it as development dependency

Answer 3

I tried adding to the path variable like others have mentioned, but still received the same error. what worked was adding this to my script:

pytesseract.pytesseract.tesseract_cmd = r"C:\Program Files (x86)\Tesseract-OCR\tesseract.exe"

Answer 4

You are probably missing tesseract-ocr from your machine. Check the installation instructions here: https://github.com/tesseract-ocr/tesseract/wiki

On a Mac, you can just install using homebrew:

brew install tesseract

It should run fine after that

Answer 5

I face this same issue. I just use this command that will help me.

sudo apt install tesseract-ocr

Note that this will only work on Ubuntu.
sudo is a Unix exclusive command (Linux, Mac, Rasbian, etc.) while apt is Ubuntu specific.

Answer 6

One simple thing that actually worked for me in Jupyter Notebook, was using double backslash instead of a single backslash in the pytesseract.pytesseract.tesseract_cmd path:

pytesseract.pytesseract.tesseract_cmd = 'C:\\Program Files (x86)\\Tesseract-OCR\\tesseract.exe'
