Advantages of Live Inference

Seamless Real-Time Object Detection: Streamlit combined with YOLOv8 enables real-time object detection directly from your webcam feed. This allows for immediate analysis and insights, making it ideal for applications requiring instant feedback.
User-Friendly Deployment: Streamlit's interactive interface makes it easy to deploy and use the application without extensive technical knowledge. Users can start live inference with a simple click, enhancing accessibility and usability.
Efficient Resource Utilization: YOLOv8 optimized algorithm ensure high-speed processing with minimal computational resources. This efficiency allows for smooth and reliable webcam inference even on standard hardware, making advanced computer vision accessible to a wider audience.

Streamlit Application Code

!!! tip "Ultralytics Installation"

Before you start building the application, ensure you have the Ultralytics Python Package installed. You can install it using the command **pip install ultralytics**

!!! Example "Streamlit Application"

=== "Python"

    ```python
    from ultralytics import solutions

    solutions.inference()

    ### Make sure to run the file using command `streamlit run <file-name.py>`
    ```

=== "CLI"

    ```bash
    yolo streamlit-predict
    ```

This will launch the Streamlit application in your default web browser. You will see the main title, subtitle, and the sidebar with configuration options. Select your desired YOLOv8 model, set the confidence and NMS thresholds, and click the "Start" button to begin the real-time object detection.

You can optionally supply a specific model in Python:

!!! Example "Streamlit Application with a custom model"

=== "Python"

    ```python
    from ultralytics import solutions

    # Pass a model as an argument
    solutions.inference(model="path/to/model.pt")

    ### Make sure to run the file using command `streamlit run <file-name.py>`
    ```
