Building Interactive Web Apps with Gradio

A Open-source Python Course: From Beginner to Advanced (2024)



Introduction

This open-source Python tutorial will guide you in quickly building demos or web applications with Gradio. You’ll start by setting up your Python environment and end with deploying interactive apps. Learn to make interfaces for text and images, improve the user experience with layout customization, and manage complex interactions.

The course will also cover processing remote sensing data with Gradio and GDAL for tasks like image enhancement and slope analysis. You’ll discover how to create interactive maps with Gradio and Foliumap, enabling dynamic geospatial data visualization.

Designed to equip you with the skills to integrate machine learning models and deploy your apps on Hugging Face Spaces, the course includes practical examples, demos, and assignments. By completing the tutorial, you’ll be able to build, deploy, and share interactive web applications confidently and efficiently.



Comprehensive Installation Guide

1. Setting Up a Virtual Environment

To ensure compatibility and isolate dependencies, create a virtual environment named “gradiotask” or another name you prefer for this Gradio tutorial. This tutorial is built using Python 3.10.6. We recommend configuring a Python version 3.10 or above for the best experience.

  • Creating and Activating the Virtual Environment Use the following command to create a new environment with Python 3.10.6: bash conda create -n gradiotask python=3.10.6
  • To activate the virtual environment, use the following command: bash conda activate gradiotask > Tips: > Remember to activate your virtual environment (gradiotask) before installing or running any packages related to this tutorial. Once you are finished, you can deactivate the environment by running conda deactivate. If necessary, you can remove the virtual environment with the command conda env remove -n gradiotask.

2. Gradio Installation

Gradio requires Python 3.8 or higher. Before you proceed, ensure you have Python installed on your system. You can download it from Python’s official website.

We recommend installing Gradio using pip, which is included by default in Python. Run this in your terminal or command prompt:

pip install gradio

Tips: Detailed installation instructions for all common operating systems are provided here.

3. Additional Libraries Installation

For running the demos and ensuring compatibility, you may need to install the following libraries with specific versions:

  • Pillow: Version 9.2.0
  • pandas: Version 1.5.0
  • GDAL: Version 3.4.3
  • numpy: Version 1.23.3
  • geopandas: Version 0.11.1
  • Shapely: Version 1.8.4
  • scikit-learn: Version 1.1.2
  • joblib: Version 1.2.0
  • openai: Version 1.16.2
  • leafmap: Version 0.29.1
  • Gradio: Version 4.27.0

Tips: To install these libraries, you can all use the pip install command, Installing GDAL can sometimes be problematic due to its size and dependencies. We recommend installing GDAL locally to avoid potential issues with online installation. Here is the GDAL 3.4.3 installation packages for windows and python 3.10. If you need other version of GDAL, please ensure you download the version that matches your operating system and Python environment.
