Watch on YouTube: Ask questions to an image using Python, Streamlit and Langchain !

This is a Streamlit application that allows users to ask questions about an uploaded image and receive responses from a conversational AI agent. The agent uses the OpenAI GPT-3.5 Turbo model to generate answers based on the provided image and user input.

1. Clone the repository:

    git clone https://github.com/your-username/image-question-answering.git
   

2. Change to the project directory:

    cd  ask-question-image-web-app-streamlit-langchain
   

3. Install the required dependencies:

    pip install -r requirements.txt
   

4. Obtain an OpenAI API key. You can sign up for an API key at OpenAI.

5. Replace the placeholder API key in the main.py file with your actual OpenAI API key:

    llm = ChatOpenAI(
        openai_api_key='YOUR_API_KEY',
        temperature=0,
        model_name="gpt-3.5-turbo"
    )
   

6. Run the Streamlit application:

    streamlit run main.py
   

7. Open your web browser and go to http://localhost:8501 to access the application.

1. Upload an image by clicking the file upload button.

2. The uploaded image will be displayed.

3. Enter a question about the image in the text input field.

4. The conversational AI agent will generate a response based on the provided question and image.

5. The response will be displayed below the question input.

The application utilizes the following custom tools:

• ImageCaptionTool: Generates a textual caption for the uploaded image.
• ObjectDetectionTool: Performs object detection on the uploaded image and identifies the objects present.
