How to Run pytesseract Python Library on Ubuntu 22.04

If you're venturing into the world of image processing and text recognition using Python, you've likely encountered pytesseract. This powerful library, primarily used for Optical Character Recognition (OCR), allows users to extract text from images efficiently. However, if you're working on Ubuntu 22.04, you may be wondering how to configure pytesseract correctly, especially since many examples are tailored for Windows. In this guide, we'll help you navigate through the installation and configuration process of pytesseract on your Ubuntu system.

Understanding the Problem

Running pytesseract on Ubuntu can be challenging, particularly when you need to set the correct command for your operating system. Unlike Windows, where the installation path for Tesseract is clear (e.g., C:/Program Files (x86)/Tesseract-OCR/tesseract), Linux has a different structure. Let's break down how to get it running on Ubuntu.

Step-by-Step Guide to Install pytesseract on Ubuntu 22.04

1. Updating Your System

Before installing any new package, it's a good practice to ensure that your package list is updated. To do this, open your terminal and execute the following commands:

This installs the pytesseract library, which will allow you to interact with Tesseract OCR from Python.

3. Install Tesseract OCR Engine

Next, you need to install the Tesseract OCR engine itself, which is crucial for any OCR functionality. Use the following command:

Then press the Tab key to view all available language options.

5. Setting the Tesseract Command in Your Code

After installing Tesseract, you need to set the correct command in your Python code. In your Jupyter Notebook or Python file, specify the Tesseract command as follows:

This line sets the path to the Tesseract executable on your Ubuntu system. By default, it is installed in /usr/bin/tesseract, which is why you use this path.

Conclusion

With these steps successfully completed, you should now be able to run the pytesseract library on Ubuntu 22.04 without any hassles. By updating your system, installing both pytesseract and Tesseract OCR, and setting the command path correctly, you're all set to detect text from images using Python!
