Setting Up a Development Environment for OpenBharatOCR

This guide details how to establish a development environment for OpenBharatOCR on a Linux system (Ubuntu/Debian preferred). If you're using Windows or macOS, consider using a virtual machine or a Linux subsystem (WSL2 on Windows, Docker on macOS).

Prerequisites:

• Operating System: Linux (Ubuntu/Debian preferred)
• Python 3.6 or later: Check the version with python3 --version or python --version in your terminal. Download the latest installer from https://www.python.org/downloads/ if needed.

Installation:

• Clone the openbharatocr repository:

git clone https://github.com/essentiasoftserv/openbharatocr.git

• Create a virtual environment (recommended):

  This isolates project dependencies and avoids conflicts with system-wide packages. Use venv or virtualenv (if venv is not available):

    python3 -m venv openbharatocr_env  # Using venv
    # OR
    virtualenv openbharatocr_env      # Using virtualenv

• Activate the virtual environment:

source openbharatocr_env/bin/activate  # For venv
# OR
source openbharatocr_env/bin/activate  # For virtualenv

• Install dependencies: Navigate to the cloned repository directory and install required packages using pip:

    cd openbharatocr
    pip install -r requirements.txt

Installation

    pip install openbharatocr
