If you're working with Pytesseract and you're getting an error message that says "TesseractNotFoundError: tesseract is not installed or it's not in your path", don't worry, you're not alone. In this guide, we'll walk you through the steps to resolve this issue and get you back to working with Pytesseract.
What is Pytesseract?
Pytesseract is a Python wrapper for Google's Tesseract-OCR. It allows you to recognize text from images and PDF files, making it a valuable tool for developers who need to work with text data.
Why Am I Getting the TesseractNotFoundError?
The TesseractNotFoundError occurs when Pytesseract is unable to find the Tesseract-OCR executable on your computer. This can happen for a few different reasons:
- Tesseract-OCR is not installed on your computer
- The location of the Tesseract-OCR executable is not in your system's path
- Pytesseract is not installed correctly
How to Fix the TesseractNotFoundError
Step 1: Install Tesseract-OCR
The first step to fixing the TesseractNotFoundError is to install Tesseract-OCR on your computer. You can download the latest version of Tesseract-OCR from their official website.
Step 2: Add Tesseract-OCR to Your System's Path
Once you've installed Tesseract-OCR, you need to add it to your system's path. This will allow Pytesseract to find the Tesseract-OCR executable. Here's how to do it:
- Open the Start Menu and search for "Environment Variables"
- Click on "Edit the system environment variables"
- Click on the "Environment Variables" button
- Under the "System Variables" section, scroll down and find the "Path" variable
- Click on "Edit"
- Click on "New" and add the path to the Tesseract-OCR executable (e.g., C:\Program Files\Tesseract-OCR)
Step 3: Verify Your Installation
To verify that Tesseract-OCR is installed correctly and is in your system's path, open a command prompt and type the following command:
tesseract --version
This should return the version number of Tesseract-OCR. If you get an error message, try restarting your computer and repeating the previous steps.
Step 4: Reinstall Pytesseract
If you've followed the previous steps and you're still getting the TesseractNotFoundError, you may need to reinstall Pytesseract. You can do this with the following command:
pip uninstall pytesseract
pip install pytesseract
Step 5: Check Your Code
If you've followed all of the previous steps and you're still getting the TesseractNotFoundError, double-check your code to make sure that you're calling Pytesseract correctly. Here's an example of how to use Pytesseract to recognize text from an image:
import pytesseract
from PIL import Image
img = Image.open('example.png')
text = pytesseract.image_to_string(img)
print(text)
