!!! Note

    This guide has been tested with both [Seeed Studio reComputer J4012](https://www.seeedstudio.com/reComputer-J4012-p-5586.html) which is based on NVIDIA Jetson Orin NX 16GB running JetPack release of [JP5.1.3](https://developer.nvidia.com/embedded/jetpack-sdk-513) and [Seeed Studio reComputer J1020 v2](https://www.seeedstudio.com/reComputer-J1020-v2-p-5498.html) which is based on NVIDIA Jetson Nano 4GB running JetPack release of [JP4.6.4](https://developer.nvidia.com/jetpack-sdk-464). It is expected to work across all the NVIDIA Jetson hardware lineup including latest and legacy.

## What is NVIDIA DeepStream?

[NVIDIA's DeepStream SDK](https://developer.nvidia.com/deepstream-sdk) is a complete streaming analytics toolkit based on GStreamer for AI-based multi-sensor processing, video, audio, and image understanding. It's ideal for vision AI developers, software partners, startups, and OEMs building IVA (Intelligent Video Analytics) apps and services. You can now create stream-processing pipelines that incorporate neural networks and other complex processing tasks like tracking, video encoding/decoding, and video rendering. These pipelines enable real-time analytics on video, image, and sensor data. DeepStream's multi-platform support gives you a faster, easier way to develop vision AI applications and services on-premise, at the edge, and in the cloud.

## Prerequisites

Before you start to follow this guide:

- Visit our documentation, [Quick Start Guide: NVIDIA Jetson with Ultralytics YOLOv8](nvidia-jetson.md) to set up your NVIDIA Jetson device with Ultralytics YOLOv8
- Install [DeepStream SDK](https://developer.nvidia.com/deepstream-getting-started) according to the JetPack version

    - For JetPack 4.6.4, install [DeepStream 6.0.1](https://docs.nvidia.com/metropolis/deepstream/6.0.1/dev-guide/text/DS_Quickstart.html)
    - For JetPack 5.1.3, install [DeepStream 6.3](https://docs.nvidia.com/metropolis/deepstream/6.3/dev-guide/text/DS_Quickstart.html)

!!! Tip

    In this guide we have used the Debian package method of installing DeepStream SDK to the Jetson device. You can also visit the [DeepStream SDK on Jetson (Archived)](https://developer.nvidia.com/embedded/deepstream-on-jetson-downloads-archived) to access legacy versions of DeepStream.

## DeepStream Configuration for YOLOv8

Here we are using [marcoslucianops/DeepStream-Yolo](https://github.com/marcoslucianops/DeepStream-Yolo) GitHub repository which includes NVIDIA DeepStream SDK support for YOLO models. We appreciate the efforts of marcoslucianops for his contributions!

1.  Install dependencies

    ```bash
    pip install cmake
    pip install onnxsim
    ```

2.  Clone the following repository

    ```bash
    git clone https://github.com/marcoslucianops/DeepStream-Yolo
    cd DeepStream-Yolo
    ```

3.  Download Ultralytics YOLOv8 detection model (.pt) of your choice from [YOLOv8 releases](https://github.com/ultralytics/assets/releases). Here we use [yolov8s.pt](https://github.com/ultralytics/assets/releases/download/v8.2.0/yolov8s.pt).

    ```bash
    wget https://github.com/ultralytics/assets/releases/download/v8.2.0/yolov8s.pt
    ```

    !!! Note

        You can also use a [custom trained YOLOv8 model](https://docs.ultralytics.com/modes/train/).

4.  Convert model to ONNX

    ```bash
    python3 utils/export_yoloV8.py -w yolov8s.pt
    ```

    !!! Note "Pass the below arguments to the above command"

        For DeepStream 6.0.1, use opset 12 or lower. The default opset is 16.

        ```bash
        --opset 12
        ```

        To change the inference size (default: 640)

        ```bash
        -s SIZE
        --size SIZE
        -s HEIGHT WIDTH
        --size HEIGHT WIDTH
        ```

        Example for 1280:

        ```bash
        -s 1280
        or
        -s 1280 1280
        ```

        To simplify the ONNX model (DeepStream >= 6.0)

        ```bash
        --simplify
        ```

        To use dynamic batch-size (DeepStream >= 6.1)

        ```bash
        --dynamic
        ```

        To use static batch-size (example for batch-size = 4)

        ```bash
        --batch 4
        ```

5.  Set the CUDA version according to the JetPack version installed

    For JetPack 4.6.4:

    ```bash
    export CUDA_VER=10.2
    ```

    For JetPack 5.1.3:

    ```bash
    export CUDA_VER=11.4
    ```

6.  Compile the library

    ```bash
    make -C nvdsinfer_custom_impl_Yolo clean && make -C nvdsinfer_custom_impl_Yolo
    ```

7.  Edit the `config_infer_primary_yoloV8.txt` file according to your model (for YOLOv8s with 80 classes)

    ```bash
    [property]
    ...
    onnx-file=yolov8s.onnx
    ...
    num-detected-classes=80
    ...
    ```

8.  Edit the `deepstream_app_config` file

    ```bash
    ...
    [primary-gie]
    ...
    config-file=config_infer_primary_yoloV8.txt
    ```

9.  You can also change the video source in `deepstream_app_config` file. Here a default video file is loaded

    ```bash
    ...
    [source0]
    ...
    uri=file:///opt/nvidia/deepstream/deepstream/samples/streams/sample_1080p_h264.mp4
    ```

### Run Inference

```bash
deepstream-app -c deepstream_app_config.txt
```

!!! Note

    It will take a long time to generate the TensorRT engine file before starting the inference. So please be patient.

!!! Tip

    If you want to convert the model to FP16 precision, simply set `model-engine-file=model_b1_gpu0_fp16.engine` and `network-mode=2` inside `config_infer_primary_yoloV8.txt`

## INT8 Calibration

If you want to use INT8 precision for inference, you need to follow the steps below

1.  Set `OPENCV` environment variable

    ```bash
    export OPENCV=1
    ```

2.  Compile the library

    ```bash
    make -C nvdsinfer_custom_impl_Yolo clean && make -C nvdsinfer_custom_impl_Yolo
    ```

3.  For COCO dataset, download the [val2017](http://images.cocodataset.org/zips/val2017.zip), extract, and move to `DeepStream-Yolo` folder

4.  Make a new directory for calibration images

    ```bash
    mkdir calibration
    ```

5.  Run the following to select 1000 random images from COCO dataset to run calibration

    ```bash
    for jpg in $(ls -1 val2017/*.jpg | sort -R | head -1000); do \
        cp ${jpg} calibration/; \
    done
    ```

    !!! Note

        NVIDIA recommends at least 500 images to get a good accuracy. On this example, 1000 images are chosen to get better accuracy (more images = more accuracy). You can set it from **head -1000**. For example, for 2000 images, **head -2000**. This process can take a long time.

6.  Create the `calibration.txt` file with all selected images

    ```bash
    realpath calibration/*jpg > calibration.txt
    ```

7.  Set environment variables

    ```bash
    export INT8_CALIB_IMG_PATH=calibration.txt
    export INT8_CALIB_BATCH_SIZE=1
    ```

    !!! Note

        Higher INT8_CALIB_BATCH_SIZE values will result in more accuracy and faster calibration speed. Set it according to you GPU memory.

8.  Update the `config_infer_primary_yoloV8.txt` file

    From

    ```bash
    ...
    model-engine-file=model_b1_gpu0_fp32.engine
    #int8-calib-file=calib.table
    ...
    network-mode=0
    ...
    ```

    To

    ```bash
    ...
    model-engine-file=model_b1_gpu0_int8.engine
    int8-calib-file=calib.table
    ...
    network-mode=1
    ...
    ```

### Run Inference

```bash
deepstream-app -c deepstream_app_config.txt
```

## MultiStream Setup

To set up multiple streams under a single deepstream application, you can do the following changes to the `deepstream_app_config.txt` file

1. Change the rows and columns to build a grid display according to the number of streams you want to have. For example, for 4 streams, we can add 2 rows and 2 columns.

    ```bash
    [tiled-display]
    rows=2
    columns=2
    ```

2. Set `num-sources=4` and add `uri` of all the 4 streams

    ```bash
    [source0]
    enable=1
    type=3
    uri=<path_to_video>
    uri=<path_to_video>
    uri=<path_to_video>
    uri=<path_to_video>
    num-sources=4
    ```

### Run Inference

```bash
deepstream-app -c deepstream_app_config.txt
```

<div align=center><img width=1000 src="https://github.com/ultralytics/ultralytics/assets/20147381/c2b327c8-75a4-4bc9-8e2d-cf023862a5d6" alt="Multistream setup"></div>
