How to Deploy a Gradio Application on Render: A Step-by-Step Guide
Introduction
Deploying a Gradio application on a server allows you to share your web-based machine learning demos with a wider audience. In this guide, we'll walk you through the process of deploying a Gradio app using Render, a popular platform for hosting web applications.
Prerequisites
Before we begin, make sure you have the following:
- A Gradio application developed and tested locally.
- A GitHub account with your Gradio app code pushed to a repository.
- A Render account.
Steps to Deploy
1. Prepare Your Gradio App
First, ensure your Gradio app runs correctly on your local machine. Use the requirements.txt
file to manage your dependencies and a virtual environment to isolate your app.
# Activate virtual environment and install dependencies
source venv/bin/activate
pip install -r requirements.txt
# Run your Gradio app locally
uvicorn run:app --reload
Check the local deployment to confirm everything works as expected.
2. Push Your Code to GitHub
Commit your code changes and push them to your GitHub repository.
git add .
git commit -m "Ready for deployment"
git push origin main
You can find the repository here.
3. Set Up Render
Log in to your Render account and connect it to your GitHub repository.
- Click on "New" and select "Web Service".
- Choose the repository containing your Gradio app.
4. Configure Render Settings
Fill in the necessary details:
-
Name: A descriptive name for your app, e.g.,
gradio-demo-app
. -
Region: Select the region closest to your target users.
-
Branch: Ensure it's set to
main
. -
Build Command: Leave it as default.
-
Start Command:
uvicorn main:app --host 0.0.0.0 --port 5000
-
Python Version: Add an environment variable
PYTHON_VERSION
and set it to your local Python version, e.g.,3.9.17
.
5. Deploy the Application
Select the free tier for hosting, and then click "Create Web Service". Render will start the deployment process by creating a virtual environment, installing dependencies, and running your app.
6. Test the Deployed App
Once the deployment is complete, you will see a "Live" status. Click on the provided URL to access your deployed Gradio app. You can find the deployed app here.
Conclusion
Deploying a Gradio application on Render is straightforward and efficient. By following these steps, you can share your machine learning applications with others effortlessly.
