To run Gradio apps locally using Windows Subsystem for Linux (WSL) and Visual Studio Code (VSCode), follow these steps:

## **1. Set Up WSL**

### **Enable WSL**
1. **Windows Features Dialog:**
   - Open the Windows search bar, type "features," and select *Turn Windows Features on or off*.
   - Scroll down and check *Windows Subsystem for Linux*.
   - Click *OK* and restart your computer.

2. **PowerShell:**
   - Open PowerShell as an Administrator and run:
     ```powershell
     Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux
     ```
   - Restart your computer when prompted.

### **Install a Linux Distro**
1. Open the Microsoft Store and search for a Linux distribution (e.g., Ubuntu).
2. Install and launch the distribution.
3. Follow the prompts to complete the installation and create a user ID and password.

## **2. Set Up Visual Studio Code with WSL**

### **Install VSCode and WSL Extension**
1. Download and install [Visual Studio Code](https://code.visualstudio.com/).
2. Install the *Remote - WSL* extension from the VSCode marketplace.

### **Open a WSL Terminal in VSCode**
1. Open your WSL terminal (e.g., Ubuntu).
2. Navigate to your project directory.
3. Type `code .` to open the current directory in VSCode.

## **3. Install and Run Gradio in a Virtual Environment**

### **Create a Virtual Environment**
1. In your WSL terminal, navigate to your project directory:
   ```bash
   cd /path/to/your/project
   ```
2. Create a virtual environment:
   ```bash
   python3 -m venv gradio-env
   ```
3. Activate the virtual environment:
   ```bash
   source gradio-env/bin/activate
   ```

### **Install Gradio**
1. With the virtual environment activated, install Gradio:
   ```bash
   pip install gradio
   ```

### **Run the App**

   ```
2. Run the Gradio app:
   ```bash
   python app.py
   ```
3. The app will open in a browser at `http://localhost:7860`.

### **Hot Reload Mode (Optional)**
For development convenience, you can use Gradio's hot reload mode:
```bash
gradio app.py
```

This setup allows you to develop and run Gradio apps efficiently using WSL and VSCode, leveraging the power of a Linux environment on a Windows machine[1][3][4][5].
