|
|
### Convert model
|
|
|
|
#### 1. Download the YOLOv7 repo and install the requirements
|
|
|
|
```
|
|
git clone https://github.com/WongKinYiu/yolov7.git
|
|
cd yolov7
|
|
pip3 install -r requirements.txt
|
|
```
|
|
|
|
**NOTE**: It is recommended to use Python virtualenv.
|
|
|
|
#### 2. Copy conversor
|
|
|
|
Copy the `gen_wts_yoloV7.py` file from `DeepStream-Yolo/utils` directory to the `yolov7` folder.
|
|
|
|
#### 3. Download the model
|
|
|
|
Download the `pt` file from [YOLOv7](https://github.com/WongKinYiu/yolov7/releases/) releases (example for YOLOv7)
|
|
|
|
```
|
|
wget hhttps://github.com/WongKinYiu/yolov7/releases/download/v0.1/yolov7.pt
|
|
```
|
|
|
|
**NOTE**: You can use your custom model, but it is important to keep the YOLO model reference (`yolov7_`) in you `cfg` and `weights`/`wts` filenames to generate the engine correctly.
|
|
|
|
#### 4. Reparameterize your model
|
|
|
|
[YOLOv7](https://github.com/WongKinYiu/yolov7/releases/) and it's variants can't be directly converted to engine file. Therefore, you will have to reparameterize your model using the code [here](https://github.com/WongKinYiu/yolov7/blob/main/tools/reparameterization.ipynb). Make sure to convert your checkpoints in yolov7 repository, and then save your reparmeterized checkpoints for conversion in the next step.
|
|
|
|
#### 5. Convert model
|
|
|
|
Generate the `cfg` and `wts` files (example for YOLOv7)
|
|
|
|
```
|
|
python3 gen_wts_yoloV7.py -w yolov7.pt
|
|
```
|
|
|
|
**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
|
|
```
|
|
|
|
#### 6. Copy generated files
|
|
|
|
Copy the generated `cfg` and `wts` files to the `DeepStream-Yolo` folder.
|
|
|
|
##
|
|
|
|
### Compile the lib
|
|
|
|
Open the `DeepStream-Yolo` folder and compile the lib
|
|
|
|
* 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 6.1.1 / 6.1 on Jetson platform
|
|
|
|
```
|
|
CUDA_VER=11.4 make -C nvdsinfer_custom_impl_Yolo
|
|
```
|
|
|
|
* DeepStream 6.0.1 / 6.0 on Jetson platform
|
|
|
|
```
|
|
CUDA_VER=10.2 make -C nvdsinfer_custom_impl_Yolo
|
|
```
|
|
|
|
##
|
|
|
|
### Edit the config_infer_primary_yoloV7 file
|
|
|
|
Edit the `config_infer_primary_yoloV7.txt` file according to your model (example for YOLOv7)
|
|
|
|
```
|
|
[property]
|
|
...
|
|
custom-network-config=yolov7.cfg
|
|
model-file=yolov7.wts
|
|
...
|
|
```
|
|
|
|
##
|
|
|
|
### Edit the deepstream_app_config file
|
|
|
|
```
|
|
...
|
|
[primary-gie]
|
|
...
|
|
config-file=config_infer_primary_yoloV7.txt
|
|
```
|
|
|
|
##
|
|
|
|
### Testing the model
|
|
|
|
```
|
|
deepstream-app -c deepstream_app_config.txt
|
|
```
