# DeepStream-Yolo

NVIDIA DeepStream SDK 8.0 / 7.1 / 7.0 / 6.4 / 6.3 / 6.2 / 6.1.1 / 6.1 / 6.0.1 / 6.0 / 5.1  configuration for YOLO models

--------------------------------------------------------------------------------------------------
### For now, I am limited for some updates. Thank you for understanding.

### YOLO-Seg: https://github.com/marcoslucianops/DeepStream-Yolo-Seg
### YOLO-Face: https://github.com/marcoslucianops/DeepStream-Yolo-Face
--------------------------------------------------------------------------------------------------
### Important: please export the ONNX model with the new export file, generate the TensorRT engine again with the updated files, and use the new config_infer_primary file according to your model

### Basic usage

#### 1. Download the repo

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

#### 2. Download the `cfg` and `weights` files from [Darknet](https://github.com/AlexeyAB/darknet) repo to the DeepStream-Yolo folder

#### 3. Compile the lib

3.1. Set the `CUDA_VER` according to your DeepStream version

```
export CUDA_VER=XY.Z
```

* x86 platform

```
  DeepStream 8.0 = 12.8
  DeepStream 7.1 = 12.6
  DeepStream 7.0 / 6.4 = 12.2
  DeepStream 6.3 = 12.1
  DeepStream 6.2 = 11.8
  DeepStream 6.1.1 = 11.7
  DeepStream 6.1 = 11.6
  DeepStream 6.0.1 / 6.0 = 11.4
  DeepStream 5.1 = 11.1
  ```

* Jetson platform

```
  DeepStream 8.0 = 13.0
  DeepStream 7.1 = 12.6
  DeepStream 7.0 / 6.4 = 12.2
  DeepStream 6.3 / 6.2 / 6.1.1 / 6.1 = 11.4
  DeepStream 6.0.1 / 6.0 / 5.1 = 10.2
  ```

3.2. Make the lib

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

#### 4. Edit the `config_infer_primary.txt` file according to your model (example for YOLOv4)

```
[property]
...
custom-network-config=yolov4.cfg
model-file=yolov4.weights
...
```

**NOTE**: For **Darknet** models, by default, the dynamic batch-size is set. To use static batch-size, uncomment the line

```
...
force-implicit-batch-dim=1
...
```

#### 5. Run

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

**NOTE**: The TensorRT engine file may take a very long time to generate (sometimes more than 10 minutes).

**NOTE**: If you want to use YOLOv2 or YOLOv2-Tiny models, change the `deepstream_app_config.txt` file before run it

```
...
[primary-gie]
...
config-file=config_infer_primary_yoloV2.txt
...
```

### Docker usage

* x86 platform

```
  nvcr.io/nvidia/deepstream:8.0-gc-triton-devel
  nvcr.io/nvidia/deepstream:8.0-triton-multiarch
  ```

* Jetson platform

```
  nvcr.io/nvidia/deepstream:8.0-triton-multiarch
  ```

**NOTE**: To compile the `nvdsinfer_custom_impl_Yolo`, you need to install the g++ inside the container

```
apt-get install build-essential
```

**NOTE**: With DeepStream 8.0, the docker containers do not package libraries necessary for certain multimedia operations like audio data parsing, CPU decode, and CPU encode. This change could affect processing certain video streams/files like mp4 that include audio track. Please run the below script inside the docker images to install additional packages that might be necessary to use all of the DeepStreamSDK features:

```
/opt/nvidia/deepstream/deepstream/user_additional_install.sh
```

### NMS Configuration

To change the `nms-iou-threshold`, `pre-cluster-threshold` and `topk` values, modify the config_infer file

```
[class-attrs-all]
nms-iou-threshold=0.45
pre-cluster-threshold=0.25
topk=300
```

**NOTE**: Make sure to set `cluster-mode=2` in the config_infer file.

### Notes

1. Sometimes while running gstreamer pipeline or sample apps, user can encounter error: `GLib (gthread-posix.c): Unexpected error from C library during 'pthread_setspecific': Invalid argument.  Aborting.`. The issue is caused because of a bug in `glib 2.0-2.72` version which comes with Ubuntu 22.04 by default. The issue is addressed in `glib 2.76` and its installation is required to fix the issue (https://github.com/GNOME/glib/tree/2.76.6).

- Migrate `glib` to newer version

```
      pip3 install meson
      pip3 install ninja
      ```

**NOTE**: It is recommended to use Python virtualenv.

```
      git clone https://github.com/GNOME/glib.git
      cd glib
      git checkout 2.76.6
      meson build --prefix=/usr
      ninja -C build/
      cd build/
      ninja install
      ```

- Check and confirm the newly installed glib version:

```
      pkg-config --modversion glib-2.0
      ```

2. Sometimes with RTSP streams the application gets stuck on reaching EOS. This is because of an issue in rtpjitterbuffer component. To fix this issue, a script has been provided with required details to update gstrtpmanager library.

```
    /opt/nvidia/deepstream/deepstream/update_rtpmanager.sh
    ```

### Extract metadata

You can get metadata from DeepStream using Python and C/C++. For C/C++, you can edit the `deepstream-app` or `deepstream-test` codes. For Python, your can install and edit [deepstream_python_apps](https://github.com/NVIDIA-AI-IOT/deepstream_python_apps).

Basically, you need manipulate the `NvDsObjectMeta` ([Python](https://docs.nvidia.com/metropolis/deepstream/dev-guide/python-api/PYTHON_API/NvDsMeta/NvDsObjectMeta.html) / [C/C++](https://docs.nvidia.com/metropolis/deepstream/dev-guide/sdk-api/struct__NvDsObjectMeta.html)) `and NvDsFrameMeta` ([Python](https://docs.nvidia.com/metropolis/deepstream/dev-guide/python-api/PYTHON_API/NvDsMeta/NvDsFrameMeta.html) / [C/C++](https://docs.nvidia.com/metropolis/deepstream/dev-guide/sdk-api/struct__NvDsFrameMeta.html)) to get the label, position, etc. of bboxes.
