DALL-E on Google Colab

Artificial intelligence has come a long way over the past couple of years, with groundbreaking advancements in deep learning, image generation, and natural language processing. One such revolutionary AI model is OpenAI's Dall-E, designed to generate images from text descriptions.

In this tutorial, we will go over the basics of integrating Dall-E into your application using Google Colab. Google Colab is a collaborative platform that allows you to run and share Python code in your browser, making it an ideal tool for experimenting with Dall-E. We'll walk you through the entire process, from establishing a fresh Google Colab notebook to installing the relevant packages and developing the code to create photos using Dall-E.

## Prerequisites

Before we start, ensure that you have the following:

  1. A Google account (to access and use Google Colab)
  2. Basic knowledge of Python programming
  3. An OpenAI API key which can be obtained from the [OpenAI website](https://www.openai.com/) (more on this later)

Setting up Dall-E with Google Colab

In this guide, I will show you how to use DALL-E on Google Colab, which is a free online platform for running Python code and vry easy if you have basic coding skills.

Step 1: Start by creating a New Google Colab Notebook

To create a new Google Colab notebook, follow these steps:

  1. Log in to your Google account
  2. Navigate to the Google Colab homepage: https://colab.research.google.com/?
  3. Click on "File" in the menu bar, followed by "New Notebook" (or use the keyboard shortcut: Ctrl+Shift+N)

A new blank Colab notebook will be created, and you're all set to start programming! Congrats , you see it is easy.

Step 2: Installing the OpenAI Package

In your newly created Google Colab notebook, type the following command in the first cell to install the OpenAI package using pip. This package is essential for using Dall-E and other OpenAI models.

  colab    install openai
!pip install openai

Press Shift+Enter to execute the cell and install the package. The installation may take a few moments.

Step 3: Importing OpenAI and Other Required Libraries

After the installation is complete, import the required libraries in your notebook using the following code:

import openai
from IPython.display import Image, display
  • openai provides access to the Dall-E API and other OpenAI models.
  • IPython.display is used to display the images generated by Dall-E within the notebook.

Step 4: Adding Your OpenAI API Key

To use Dall-E, you need an API key. If you haven't already, obtain an API key by creating an account on the OpenAI website. Once you have the API key, add it to your program using the following line of code. Remember to replace <your_api_key> with your actual API key.

openai.api_key = "<your_api_key>"

Step 5: Writing the Dall-E Image Generation Function

Create a function named generate_image to generate images using Dall-E. This function will take a prompt (text description) as its input and display the resulting image. The code for this function is as follows:

def generate_image(prompt):
    # Generate image URL using Dall-E API
    response = openai.Image.create(
    image_url = response['data'][0]['url']
    # Download and display the generated image
    display(Image(url=image_url, width=500, height=500))
    print("Generated image URL:", image_url)

This function calls the Dall-E API to generate an image URL using the user-provided prompt and then utilizes the IPython.display library to download and display the image alongside its URL.

Step 6: Final let us Test the Dall-E Image Generation

Now let's test our image generation function with a sample prompt. In a new cell, type the following code:

prompt = "A futuristic city skyline"

Press Shift+Enter to execute the cell. You will see the AI-generated image of a futuristic city skyline, as described by the text prompt. The unique image URL will also be displayed below the image.

In this tutorial, you learned how to set up Dall-E using Google Colab and generate images based on text descriptions. By utilizing this seamless integration, you can now create fun, interesting, and impressive AI-generated images with minimal effort. As OpenAI continues to enhance and improve their models, you'll be able to explore even more capabilities and applications!

The complete code from this tutorial can be found in the following Github repository: Dalle_Example on Github. Remember to replace the "username" placeholder with your own Github username, and feel free to contribute or expand the project as you explore the world of Dall-E!


  1. What is Dall-E?**

    Dall-E is an artificial intelligence model developed by OpenAI that generates images from textual descriptions. It's capable of creating unique and visually stunning images based on textual inputs, showing a remarkable level of creativity and artistic expression.

  2. What is Google Colab?**

    Google Colab is a free cloud-based platform provided by Google that allows you to write, execute, and share Python code in your browser. It offers a Jupyter Notebook-like environment, which lets you run code on powerful GPUs and TPUs and share your work easily with others.
  3. How can I use Dall-E on Google Colab?** To use Dall-E on Google Colab, you first need to find an existing notebook with the necessary code and dependencies set up or create one yourself. OpenAI has not released the official Dall-E model, but you can find several unofficial implementations shared by the AI community. Once you have a Dall-E notebook, open it in Google Colab, and start executing the code cells to generate images based on your given textual descriptions.
  4. Can I use the Dall-E model with Google Colab's free GPU?**

    Yes, you can use Google Colab's free GPU to run most Dall-E notebooks. To enable GPU support, click on "Runtime" in the toolbar, select "Change runtime type," and choose "GPU" from the "Hardware accelerator" dropdown menu. Keep in mind, however, that running the Dall-E model may take a significant amount of time depending on the particular implementation, GPU performance, and availability of resources.

  5. After generating images using Dall-E on Google Colab, how can I save or download them?**

    Once the images are generated in your Google Colab notebook, you can save them to your Google Drive or download them directly to your local device. To save to Google Drive, you can use the Google Colab integration with Google Drive. To download them directly, right-click on the displayed image and select "Save image as" or use the provided code (if any) in the notebook to download the image file.
