Interactive Media App Code Breakdown: A Friendly Walkthrough

Alright, let's take a closer look at how the Interactive Media App works. I'll walk you through the code in a simple, friendly way, explaining what each part does and how it all fits together to create this cool app.

Setting Up Your Interactive Media App: Getting Started

Before we dive into the fun part of coding our Interactive Media App, there are a few important setup steps we need to follow. This involves getting some access keys and installing necessary packages. Don't worry, I'll guide you through each step!

Step 1: Grab Your Access Tokens

Clarifai Personal Access Token

1. Visit Clarifai: Head over to Clarifai's security settings page.
2. Get Your Token: Here, you'll find your personal access token. This is like a special password that lets your app talk to Clarifai's services. Copy this token.

OpenAI API Key

1. Go to OpenAI: Visit the OpenAI website and log into your account.
2. Retrieve Your Key: Find where they list your API key. This key is what allows your app to interact with OpenAI's powerful AI models.

Step 1: Set Up a Virtual Environment

Before starting with your project, it's important to create a virtual environment. This ensures that your project has an isolated space to manage dependencies, preventing conflicts between different projects.

1. Navigate to Your Project Directory:

   • Use your terminal or command prompt to go to your project's folder.

2. Create the Virtual Environment:

   • Run the command:

     python -m venv env
     

   • This will create a new folder named env in your project directory, which contains the virtual environment.

3. Activate the Virtual Environment:

   • For Windows, run: .\env\Scripts\activate
   • For macOS/Linux, run: source env/bin/activate
   • Your command prompt should now show the name of the virtual environment, indicating that it's active.

Step 2: Set Up Your Environment File

Now that you have your keys, you need to store them safely in your project.

1. Create a .env File: In your project folder, create a new file and name it .env.

2. Add the Keys: Open this file and add your Clarifai and OpenAI keys like this:

   CLARIFAI_PAT=Your_Clarifai_Personal_Access_Token
   OPEN_AI=Your_OpenAI_API_Key

   Replace Your_Clarifai_Personal_Access_Token and Your_OpenAI_API_Key with the actual keys you copied.

Step 3: Installing Necessary Packages

Finally, you'll need to install a couple of Python packages.

1. Install Clarifai: This package lets your Python code interact with the Clarifai API.

   pip install clarifai
   

2. Install python-dotenv: This package will help your Python code read the .env file where you stored your API keys.

   pip install python-dotenv
   

3. Install streamlit: Install streamlit for faster creation of our app.

   pip install streamlit
   

Ready to Code!

With these steps completed, you're all set to start building the app. You have your access tokens safely stored and the necessary packages installed. Next up, I'll walk you through the code for creating your Interactive Media App. Let's get coding! 🚀👩‍💻👨‍💻

Starting with the Basics: Importing Libraries

import streamlit as st
from clarifai.client.model import Model
import base64
from dotenv import load_dotenv
from PIL import Image
from io import BytesIO

load_dotenv()
import os

This block is like gathering all the tools we need before we start building something. Here's what each tool does:

• streamlit (st): Think of this as our app's canvas. It's where we'll draw our user interface.
• clarifai.client.model: This is like a key to Clarifai's treasure chest, giving us access to their cool AI models.
• base64: A bit like a translator, turning images into a format that computers love to work with.
• dotenv and os: These two work together to keep our secret keys (API keys) safe and sound.
• PIL (Python Imaging Library) and BytesIO: These are our image wizards, helping us to handle and manipulate pictures.

Keeping Secrets: Environment Variables

clarifai_pat = os.getenv("CLARIFAI_PAT")
openai_api_key = os.getenv("OPEN_AI")

Here, we're retrieving the secret keys that we need to talk to Clarifai and OpenAI's services. It's like getting a special passcode to enter an exclusive club.

The Magic of Making Images: generate_image

def generate_image(user_description, api_key):
    prompt = f"You are a professional comic artist. Based on the below user's description and content, create a proper story comic: {user_description}"
    inference_params = dict(quality="standard", size="1024x1024")
    model_prediction = Model(
        f"https://clarifai.com/openai/dall-e/models/dall-e-3?api_key={api_key}"
    ).predict_by_bytes(
        prompt.encode(), input_type="text", inference_params=inference_params
    )
    output_base64 = model_prediction.outputs[0].data.image.base64
    with open("generated_image.png", "wb") as f:
        f.write(output_base64)
    return "generated_image.png"

In this function, we take what the user describes and use it to create an image. It's like telling an artist (in this case, the DALL-E model) what to paint, and then the artist whips up a beautiful image for us.

Understanding the Picture: understand_image

def understand_image(base64_image, api_key):
    prompt = "Analyze the content of this image and write a creative, engaging story that brings the scene to life. Describe the characters, setting, and actions in a way that would captivate a young audience:"
    inference_params = dict(temperature=0.2, image_base64=base64_image, api_key=api_key)
    model_prediction = Model(
        "https://clarifai.com/openai/chat-completion/models/gpt-4-vision"
    ).predict_by_bytes(
        prompt.encode(), input_type="text", inference_params=inference_params
    )
    return model_prediction.outputs[0].data.text.raw

    def encode_image(image_path):
    with open(image_path, "rb") as image_file:
        return base64.b64encode(image_file.read()).decode("utf-8")

After we have our image, this function steps in. It looks at the picture and tells us a story about it. We're using another AI model here to turn images into creative stories.

Speaking the Story: text_to_speech

def text_to_speech(input_text, api_key):
    inference_params = dict(voice="alloy", speed=1.0, api_key=api_key)
    model_prediction = Model(
        "https://clarifai.com/openai/tts/models/openai-tts-1"
    ).predict_by_bytes(
        input_text.encode(), input_type="text", inference_params=inference_params
    )
    audio_base64 = model_prediction.outputs[0].data.audio.base64
    return audio_base64

Now, we take the story that our AI model wrote for us and turn it into speech. It's like turning a book into an audiobook so you can listen to the story instead of reading it.

Bringing It All to Life: main

def main():
    st.set_page_config(page_title="Interactive Media Creator", layout="wide")
    st.title("Interactive Media Creator")

    with st.sidebar:
        st.header("Controls")
        image_description = st.text_area("Description for Image Generation", height=100)
        generate_image_btn = st.button("Generate Image")

    col1, col2 = st.columns(2)

    with col1:
        st.header("Comic Art")
        if generate_image_btn and image_description:
            with st.spinner("Generating image..."):
                image_path = generate_image(image_description, clarifai_pat)
                if image_path:
                    st.image(
                        image_path,
                        caption="Generated Comic Image",
                        use_column_width=True,
                    )
                    st.success("Image generated!")
                else:
                    st.error("Failed to generate image.")

    with col2:
        st.header("Story")
        if generate_image_btn and image_description:
            with st.spinner("Creating a story..."):
                base64_image = encode_image(image_path)
                understood_text = understand_image(base64_image, openai_api_key)
                audio_base64 = text_to_speech(understood_text, openai_api_key)
                st.audio(audio_base64, format="audio/mp3")
                st.success("Audio generated from image understanding!")

This is where we build our app's interface and put everything together. We set up a space for users to type in their descriptions, a button to make the magic happen, and areas to display the generated image and story.

Running the Show

if __name__ == "__main__":
    main()

And finally, this little bit of code is what starts everything off. It's like the "Open for Business" sign that gets everything rolling.

Save your code in main.py and run it

streamlit run main.py
