!!! Note

    This guide has been tested with Raspberry Pi 4 and Raspberry Pi 5 running the latest [Raspberry Pi OS Bookworm (Debian 12)](https://www.raspberrypi.com/software/operating-systems/). Using this guide for older Raspberry Pi devices such as the Raspberry Pi 3 is expected to work as long as the same Raspberry Pi OS Bookworm is installed.

## What is Raspberry Pi?

Raspberry Pi is a small, affordable, single-board computer. It has become popular for a wide range of projects and applications, from hobbyist home automation to industrial uses. Raspberry Pi boards are capable of running a variety of operating systems, and they offer GPIO (General Purpose Input/Output) pins that allow for easy integration with sensors, actuators, and other hardware components. They come in different models with varying specifications, but they all share the same basic design philosophy of being low-cost, compact, and versatile.

## What is Raspberry Pi OS?

[Raspberry Pi OS](https://www.raspberrypi.com/software) (formerly known as Raspbian) is a Unix-like operating system based on the Debian GNU/Linux distribution for the Raspberry Pi family of compact single-board computers distributed by the Raspberry Pi Foundation. Raspberry Pi OS is highly optimized for the Raspberry Pi with ARM CPUs and uses a modified LXDE desktop environment with the Openbox stacking window manager. Raspberry Pi OS is under active development, with an emphasis on improving the stability and performance of as many Debian packages as possible on Raspberry Pi.

## Flash Raspberry Pi OS to Raspberry Pi

The first thing to do after getting your hands on a Raspberry Pi is to flash a micro-SD card with Raspberry Pi OS, insert into the device and boot into the OS. Follow along with detailed [Getting Started Documentation by Raspberry Pi](https://www.raspberrypi.com/documentation/computers/getting-started.html) to prepare your device for first use.

## Set Up Ultralytics

There are two ways of setting up Ultralytics package on Raspberry Pi to build your next Computer Vision project. You can use either of them.

- [Start with Docker](#start-with-docker)
- [Start without Docker](#start-without-docker)

### Start with Docker

The fastest way to get started with Ultralytics YOLOv8 on Raspberry Pi is to run with pre-built docker image for Raspberry Pi.

Execute the below command to pull the Docker container and run on Raspberry Pi. This is based on [arm64v8/debian](https://hub.docker.com/r/arm64v8/debian) docker image which contains Debian 12 (Bookworm) in a Python3 environment.

```bash
t=ultralytics/ultralytics:latest-arm64 && sudo docker pull $t && sudo docker run -it --ipc=host $t
```

After this is done, skip to [Use NCNN on Raspberry Pi section](#use-ncnn-on-raspberry-pi).

### Start without Docker

#### Install Ultralytics Package

Here we will install Ultralyics package on the Raspberry Pi with optional dependencies so that we can export the PyTorch models to other different formats.

1. Update packages list, install pip and upgrade to latest

    ```bash
    sudo apt update
    sudo apt install python3-pip -y
    pip install -U pip
    ```

2. Install `ultralytics` pip package with optional dependencies

    ```bash
    pip install ultralytics[export]
    ```

3. Reboot the device

    ```bash
    sudo reboot
    ```

## Use NCNN on Raspberry Pi

Out of all the model export formats supported by Ultralytics, [NCNN](https://docs.ultralytics.com/integrations/ncnn) delivers the best inference performance when working with Raspberry Pi devices because NCNN is highly optimized for mobile/ embedded platforms (such as ARM architecture). Therefore our recommendation is to use NCNN with Raspberry Pi.

## Convert Model to NCNN and Run Inference

The YOLOv8n model in PyTorch format is converted to NCNN to run inference with the exported model.

!!! Example

    === "Python"

        ```python
        from ultralytics import YOLO

        # Load a YOLOv8n PyTorch model
        model = YOLO('yolov8n.pt')

        # Export the model to NCNN format
        model.export(format='ncnn')  # creates 'yolov8n_ncnn_model'

        # Load the exported NCNN model
        ncnn_model = YOLO('yolov8n_ncnn_model')

        # Run inference
        results = ncnn_model('https://ultralytics.com/images/bus.jpg')
        ```
    === "CLI"

        ```bash
        # Export a YOLOv8n PyTorch model to NCNN format
        yolo export model=yolov8n.pt format=ncnn  # creates 'yolov8n_ncnn_model'

        # Run inference with the exported model
        yolo predict model='yolov8n_ncnn_model' source='https://ultralytics.com/images/bus.jpg'
        ```

!!! Tip
    
    For more details about supported export options, visit the [Ultralytics documentation page on deployment options](https://docs.ultralytics.com/guides/model-deployment-options).

## Raspberry Pi 5 vs Raspberry Pi 4 YOLOv8 Benchmarks

YOLOv8 benchmarks were run by the Ultralytics team on nine different model formats measuring speed and accuracy: PyTorch, TorchScript, ONNX, OpenVINO, TF SavedModel, TF Graphdef, TF Lite, PaddlePaddle, NCNN. Benchmarks were run on both Raspberry Pi 5 and Raspberry Pi 4 at FP32 precision with default input image size of 640.

!!! Note

    We have only included benchmarks for YOLOv8n and YOLOv8s models because other models sizes are too big to run on the Raspberry Pis and does not offer decent performance.

## Reproduce Our Results

To reproduce the above Ultralytics benchmarks on all [export formats](../modes/export.md), run this code:

!!! Example

    === "Python"

        ```python
        from ultralytics import YOLO

        # Load a YOLOv8n PyTorch model
        model = YOLO('yolov8n.pt')

        # Benchmark YOLOv8n speed and accuracy on the COCO8 dataset for all all export formats
        results = model.benchmarks(data='coco8.yaml', imgsz=640)
        ```
    === "CLI"

        ```bash
        # Benchmark YOLOv8n speed and accuracy on the COCO8 dataset for all all export formats
        yolo benchmark model=yolov8n.pt data=coco8.yaml imgsz=640
        ```

    Note that benchmarking results might vary based on the exact hardware and software configuration of a system, as well as the current workload of the system at the time the benchmarks are run. For the most reliable results use a dataset with a large number of images, i.e. `data='coco8.yaml' (4 val images), or `data='coco.yaml'` (5000 val images).

## Use Raspberry Pi Camera

When using Raspberry Pi for Computer Vision projects, it can be essentially to grab real-time video feeds to perform inference. The onboard MIPI CSI connector on the Raspberry Pi allows you to connect official Raspberry PI camera modules. In this guide, we have used a [Raspberry Pi Camera Module 3](https://www.raspberrypi.com/products/camera-module-3) to grab the video feeds and perform inference using YOLOv8 models.

!!! Tip

    Learn more about the [different camera modules offered by Raspberry Pi](https://www.raspberrypi.com/documentation/accessories/camera.html) and also [how to get started with the Raspberry Pi camera modules](https://www.raspberrypi.com/documentation/computers/camera_software.html#introducing-the-raspberry-pi-cameras).

!!! Note

    Raspberry Pi 5 uses smaller CSI connectors than the Raspberry Pi 4 (15-pin vs 22-pin), so you will need a [15-pin to 22pin adapter cable](https://www.raspberrypi.com/products/camera-cable) to connect to a Raspberry Pi Camera.

### Test the Camera

Execute the following command after connecting the camera to the Raspberry Pi. You should see a live video feed from the camera for about 5 seconds.

```bash
rpicam-hello
```

!!! Tip

    Learn more about [`rpicam-hello` usage on official Raspberry Pi documentation](https://www.raspberrypi.com/documentation/computers/camera_software.html#rpicam-hello) 

### Initiate TCP Stream with `rpicam-vid`

We need to iniate a TCP stream from the connected camera so that we can use this stream URL as an input when we are inferencing later. Execute the following command to start the TCP stream.

```bash
rpicam-vid -n -t 0 --inline --listen -o tcp://127.0.0.1:8888
```

!!! Tip

    Learn more about [`rpicam-vid` usage on official Raspberry Pi documentation](https://www.raspberrypi.com/documentation/computers/camera_software.html#rpicam-vid) 

### Perform YOLOv8 Inference

With the TCP stream initiated, you can perform YOLOv8 inference.

!!! Example

    === "Python"

        ```python
        from ultralytics import YOLO

        # Load a YOLOv8n PyTorch model
        model = YOLO('yolov8n.pt')

        # Run inference
        results = model('tcp://127.0.0.1:8888')
        ```
    === "CLI"

        ```bash
        yolo predict model=yolov8n.pt source='tcp://127.0.0.1:8888'
        ```

!!! Tip

    Check our document on [Inference Sources](https://docs.ultralytics.com/modes/predict/#inference-sources) if you want to change the image/ video input type

## Best Practices when using Raspberry Pi

There are a couple of best practices to follow in order to enable maximum performance on Raspberry Pis running YOLOv8.

1. Use an SSD

    When using Raspberry Pi for 24x7 continued usage, it is recommend to use an SSD for the system because an SD card will not be able to withstand continuous writes and might get broken. With the onboard PCIe connector on the Raspberry Pi 5, now you can connect SSDs using an adapter such as the [NVMe Base for Raspberry Pi 5](https://shop.pimoroni.com/products/nvme-base).

2. Flash without GUI

    When flashing Raspberry Pi OS, you can choose to not install the Desktop environment (Raspberry Pi OS Lite) and this can save a little bit of RAM on the device, leaving more space for computer vision processing.
