Welcome to an exciting dive into the world of text-to-image generation using the Text-to-Image Playground powered by Stable Diffusion V2! This repository allows text enthusiasts to generate images from text descriptions, all while having a hands-on, enjoyable experience. Let’s explore how you can get started with it!

Fast Usage: Simple Steps to Generate Images

To tinker around with the DALL-E Playground, follow these steps for a smooth start:

1. Launch the DALL-E backend using Google Colab. You can access it here.
2. In the output of the last executed cell, copy the URL. Look for the line stating: “Your URL is:”
3. Be patient and wait for the backend to fully load. This should take about 2 minutes, and you should see “Image generation server is up and running!”
4. Now, browse to this link, where you will replace the backendUrl query parameter with the URL from the previous step.

**General Note**: While you can run the backend on the free tier of Google Colab, remember that generating more than about 2 images could lead to a timeout. Consider upgrading to Colab Pro or running the notebook on a more powerful ML machine (like AWS EC2).

Local Development: Running DALL-E Playground on Your Computer

If you’re interested in cloning the DALL-E Playground and running it locally, follow these steps:

1. Clone or fork this repository.
2. Create a virtual environment: cd backend && python3 -m venv ENV_NAME.
3. Activate your virtual environment: source venv/bin/activate.
4. Install the required packages: pip install -r requirements.txt.
5. Ensure you have PyTorch and its dependencies installed by following this installation guide.
6. Run the web server with: python3 app.py --port 8080 (feel free to change 8080 to your desired port).
7. In a different terminal, navigate to the interface folder, then install frontend modules with: cd interface && npm install and run it with: npm start.
8. Copy the backend URL from step 5 and paste it into the backend URL input within the web app.

Special Instructions for Windows WSL2

If you’re using WSL2, here are specific steps to help you get everything set up:

1. Ensure you have a recent NVIDIA GeForce Game Ready or NVIDIA RTX Quadro driver installed in Windows.
2. In your Linux environment, install NVIDIA’s CUDA toolkit by following these WSL instructions.
3. Install NVIDIA’s CuDNN library using the instructions here.
4. Build and install both jaxlib and jax from source. Remember to enable CUDA during compilation: python3 build/build.py --enable_cuda. You can find more instructions here.
5. If you encounter a broken configuration file while compiling jaxlib, find the solution here.
6. Follow the local development instructions outlined above.

Note that WSL2 installs are minimally configured, so expect to install additional packages like npm, python3-pip, and others for everything to work seamlessly. For further troubleshooting, check out more here.

Docker Compose Setup

For those who prefer containerization, you can also run the DALL-E Playground using Docker:

1. Confirm that you have Docker and The NVIDIA Container Toolkit installed.
2. Clone or fork this repository.
3. Start the server with: docker-compose up (add -d to run it in the background).
4. The first run will take some time to download the required images, models, and other dependencies. Don’t worry; these will only be downloaded once and will be cached afterward.
5. Copy the backend URL from step 2 and paste it into the backend URL input within the web app. Access the web app at this link.

Troubleshooting Common Issues

In case you encounter any bumps along the way, here are some troubleshooting ideas:

• If image generation times out, consider upgrading to Colab Pro.
• Double-check that you’ve activated your virtual environment before running the server.
• Ensure all dependencies are correctly installed by revisiting the installation guides linked above.
