Art That Talks Back: A Hands-On Tutorial on Talking Images

Imagine going to an art gallery where paintings tell their stories. That’s what "Talking Images" do in practice. This tutorial shows you how to make art speak using DeepInfra models. We are going to use:

1-) deepseek-ai/Janus-Pro-7B
2-) hexgrad/Kokoro-82M

Setting Up Environment

First, let’s set up your environment. You’ll need these packages. Here’s the content of requirements.txt:

gradio
requests
python-dotenv
pillow
scipy
numpy
copy

Venv Environment Setup

Show Venv Tutorial

python -m venv venv && (venv\Scripts\activate.bat 2>nul || source venv/bin/activate) && pip install -r requirements.txt
copy

Create .env File

Next, create a .env file in your project folder. Copy your DEEPINFRA_API_TOKEN into it. Your .env file should look like this:

DEEPINFRA_API_TOKEN=your-api-token-here
copy

Replace your-api-token-here with your actual DeepInfra API token.

The Code

Here’s the Python code that makes your images talk. It uses Janus-Pro-7B to describe the image and Kokoro-82M to turn that description into audio.

import os
from io import BytesIO
import gradio as gr
import base64
import requests
from dotenv import load_dotenv, find_dotenv
from scipy.io import wavfile
import numpy as np

_ = load_dotenv(find_dotenv())

def analyze_image(image) -> str:
    url = "https://api.deepinfra.com/v1/inference/deepseek-ai/Janus-Pro-7B"
    headers = {"Authorization": f"bearer {api_token}"}
    buffered = BytesIO()
    if image.mode == "RGBA":
        image = image.convert("RGB")
    format = "JPEG" if image.format == "JPEG" else "PNG"
    image.save(buffered, format=format)
    files = {"image": ("my_image." + format.lower(), buffered.getvalue(), f"image/{format.lower()}")}
    data = {
        "question": "I am this image. You must describe me in my own voice using 'I'. State my colors, shapes, mood, and any notable features with precise detail. Examples: 'I have clouds,' 'I contain sharp lines.' Be vivid, thorough, and factual."
    }
    response = requests.post(url, headers=headers, files=files, data=data)
    return response.json()["response"]

def text_to_speech(text: str) -> tuple:
    url = "https://api.deepinfra.com/v1/inference/hexgrad/Kokoro-82M"
    headers = {
        "Authorization": f"bearer {api_token}",
        "Content-Type": "application/json"
    }
    data = {
        "text": text
    }
    response = requests.post(url, json=data, headers=headers)
    res_json = response.json()
    audio_base64 = res_json["audio"].split(",")[1]
    audio_bytes = base64.b64decode(audio_base64)
    audio_io = BytesIO(audio_bytes)
    sample_rate, audio_data = wavfile.read(audio_io)
    return sample_rate, audio_data

def make_image_talk(image):
    description = analyze_image(image)
    sample_rate, audio_data = text_to_speech(description)
    return sample_rate, audio_data

if __name__ == "__main__":
    api_token = os.environ.get("DEEPINFRA_API_TOKEN")
    interface = gr.Interface(
        fn=make_image_talk,
        inputs=gr.Image(type="pil"),
        outputs=gr.Audio(type="numpy"),
        title="Art That Talks Back",
        description="Upload an image and hear it talk!"
    )
    interface.launch()
copy
