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

Install tesseract from https://github.com/UB-Mannheim/tesseract/wiki and add the path of tesseract.exe to the Path environment variable.

Answer 2

Are you importing

from tesseract import image_to_string

Don't import from pytesseract

Answer 3

I was also facing the same issue, just add C:\Program Files (x86)\Tesseract-OCR to your path variable. If it still does not work, add C:\Program Files (x86)\Tesseract-OCR\tessdata to your path variable in a new line. And do not forget to restart your computer after adding the path variable.

Answer 4

I was also facing the same error when I was trying to make a text-extractor using pytesseract, but the solution was there in installation instructions for pytesseract in pypi site: pytesseract There are many alternatives to avoid the error, But, adding one more parameter in the method pytesseract.image_to_string solved it for me, like

tessdata_dir_config = "/usr/share/tesseract-ocr/4.00/tessdata"
output = pytesseract.image_to_string(image, lang='eng', config=tessdata_dir_config)

I came across this problem today and all the answers mentioned here helped me, but I personally had to dig a lot to solve it. So let me help all others by putting out the solution to it in a very simple form:

1. Download the executable 64 bit (32-bit if your computer is of 32 bit) exe from here.

   (Name of the file would be tesseract-ocr-w64-setup-v5.0.0.20190526 (alpha))

2. Install it. Let it install itself in the default C directory.

3. Now go to your Environment variable (Reach there by just searching it in the start menu or Go to Control Panel > System > Advanced System Settings > Environment Variables)

a) Select PATH and then Edit it. Click on NEW and add the path where it is installed (Usually C:\Program Files\Tesseract-OCR\)

Now you will not get the error!

Answer 6

Small mistake -- I knew I had to open/close my cmd to get the updated path to reflect. Using Jupyter Notebook I had to shutdown the client and re-initialize it also.
