# YOLOv6 usage
|
|
|
|
**NOTE**: You need to change the branch of the YOLOv6 repo according to the version of the model you want to convert.
|
|
|
|
**NOTE**: The yaml file is not required.

|
### Convert model
|
|
|
|
#### 1. Download the YOLOv6 repo and install the requirements
|
|
|
|
```
|
|
git clone https://github.com/meituan/YOLOv6.git
|
|
cd YOLOv6
|
|
pip3 install -r requirements.txt
|
|
pip3 install onnx onnxsim onnxruntime
|
|
```
|
|
|
|
**NOTE**: It is recommended to use Python virtualenv.
|
|
|
|
#### 2. Copy conversor
|
|
|
|
Copy the `export_yoloV6.py` file from `DeepStream-Yolo/utils` directory to the `YOLOv6` folder.
|
|
|
|
#### 3. Download the model
|
|
|
|
Download the `pt` file from [YOLOv6](https://github.com/meituan/YOLOv6/releases/) releases (example for YOLOv6-S 4.0)
|
|
|
|
```
|
|
wget https://github.com/meituan/YOLOv6/releases/download/0.4.0/yolov6s.pt
|
|
```
|
|
|
|
**NOTE**: You can use your custom model.
|
|
|
|
#### 4. Convert model
|
|
|
|
Generate the ONNX model file (example for YOLOv6-S 4.0)
|
|
|
|
```
|
|
python3 export_yoloV6.py -w yolov6s.pt --dynamic
|
|
```
|
|
|
|
**NOTE**: To simplify the ONNX model (DeepStream >= 6)
|
|
|
|
```
|
|
--simplify
|
|
```
|
|
|
|
**NOTE**: To use dynamic batch-size (DeepStream >= 6)
|
|
|
|
```
|
|
--dynamic
|
|
```
|
|
|
|
**NOTE**: To use implicit batch-size (example for batch-size = 4)
|
|
|
|
```
|
|
--batch 4
|
|
```
|
|
|
|
**NOTE**: If you are using DeepStream 5.1, remove the `--dynamic` arg and use opset 12 or lower. The default opset is 13.
|
|
|
|
```
|
|
--opset 12
|
|
```
|
|
|
|
**NOTE**: To convert a P6 model
|
|
|
|
```
|
|
--p6
|
|
```
|
|
|
|
**NOTE**: To change the inference size (defaut: 640)
|
|
|
|
```
|
|
-s SIZE
|
|
--size SIZE
|
|
-s HEIGHT WIDTH
|
|
--size HEIGHT WIDTH
|
|
```
|
|
|
|
Example for 1280
|
|
|
|
```
|
|
-s 1280
|
|
```
|
|
|
|
or
|
|
|
|
```
|
|
-s 1280 1280
|
|
```
|
|
|
|
#### 5. Copy generated file
|
|
|
|
Copy the generated ONNX model file to the `DeepStream-Yolo` folder.
|
|
|
|
##
|
|
|
|
### Compile the lib
|
|
|
|
Open the `DeepStream-Yolo` folder and compile the lib
|
|
|
|
* DeepStream 6.2 on x86 platform
|
|
|
|
```
|
|
CUDA_VER=11.8 make -C nvdsinfer_custom_impl_Yolo
|
|
```
|
|
|
|
* DeepStream 6.1.1 on x86 platform
|
|
|
|
```
|
|
CUDA_VER=11.7 make -C nvdsinfer_custom_impl_Yolo
|
|
```
|
|
|
|
* DeepStream 6.1 on x86 platform
|
|
|
|
```
|
|
CUDA_VER=11.6 make -C nvdsinfer_custom_impl_Yolo
|
|
```
|
|
|
|
* DeepStream 6.0.1 / 6.0 on x86 platform
|
|
|
|
```
|
|
CUDA_VER=11.4 make -C nvdsinfer_custom_impl_Yolo
|
|
```
|
|
|
|
* DeepStream 5.1 on x86 platform
|
|
|
|
```
|
|
CUDA_VER=11.1 make -C nvdsinfer_custom_impl_Yolo
|
|
```
|
|
|
|
* DeepStream 6.2 / 6.1.1 / 6.1 on Jetson platform
|
|
|
|
```
|
|
CUDA_VER=11.4 make -C nvdsinfer_custom_impl_Yolo
|
|
```
|
|
|
|
* DeepStream 6.0.1 / 6.0 / 5.1 on Jetson platform
|
|
|
|
```
|
|
CUDA_VER=10.2 make -C nvdsinfer_custom_impl_Yolo
|
|
```
|
|
|
|
##
|
|
|
|
### Edit the config_infer_primary_yoloV6 file
|
|
|
|
Edit the `config_infer_primary_yoloV6.txt` file according to your model (example for YOLOv6-S 4.0 with 80 classes)
|
|
|
|
```
|
|
[property]
|
|
...
|
|
onnx-file=yolov6s.onnx
|
|
...
|
|
num-detected-classes=80
|
|
...
|
|
parse-bbox-func-name=NvDsInferParseYolo
|
|
...
|
|
```
|
|
|
|
**NOTE**: The **YOLOv6** resizes the input with center padding. To get better accuracy, use
|
|
|
|
```
|
|
...
|
|
maintain-aspect-ratio=1
|
|
symmetric-padding=1
|
|
...
|
|
```
|
|
|
|
**NOTE**: By default, the dynamic batch-size is set. To use implicit batch-size, uncomment the line
|
|
|
|
```
|
|
...
|
|
force-implicit-batch-dim=1
|
|
...
|
|
```
|
|
|
|
##
|
|
|
|
### Edit the deepstream_app_config file
|
|
|
|
```
|
|
...
|
|
[primary-gie]
|
|
...
|
|
config-file=config_infer_primary_yoloV6.txt
|
|
```
|
|
|
|
##
|
|
|
|
### Testing the model
|
|
|
|
```
|
|
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**: For more information about custom models configuration (`batch-size`, `network-mode`, etc), please check the [`docs/customModels.md`](customModels.md) file.
