|
### Directory tree
|
|
|
|
#### 1. Download the repo
|
|
|
|
```
|
|
git clone https://github.com/marcoslucianops/DeepStream-Yolo.git
|
|
cd DeepStream-Yolo
|
|
```
|
|
|
|
#### 2. Copy the class names file to DeepStream-Yolo folder and remane it to `labels.txt`
|
|
|
|
#### 3. Copy the `onnx` or `cfg` and `weights` files to DeepStream-Yolo folder
|
|
|
|
##
|
|
|
|
### Compile the lib
|
|
|
|
1. Set the `CUDA_VER` according to your DeepStream version
|
|
|
|
```
|
|
export CUDA_VER=XY.Z
|
|
```
|
|
|
|
* x86 platform
|
|
|
|
```
|
|
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 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
|
|
```
|
|
|
|
2. Make the lib
|
|
|
|
```
|
|
make -C nvdsinfer_custom_impl_Yolo clean && make -C nvdsinfer_custom_impl_Yolo
|
|
```
|
|
|
|
##
|
|
|
|
### Understanding and editing deepstream_app_config file
|
|
|
|
To understand and edit `deepstream_app_config.txt` file, read the [DeepStream Reference Application - Configuration Groups](https://docs.nvidia.com/metropolis/deepstream/dev-guide/text/DS_ref_app_deepstream.html#configuration-groups)

```
|
|
|
|
**NOTE**: Edit the `config-file` according to your YOLO model.
|
|
|
|
##
|
|
|
|
### Understanding and editing config_infer_primary file
|
|
|
|
To understand and edit `config_infer_primary.txt` file, read the [DeepStream Plugin Guide - Gst-nvinfer File Configuration Specifications](https://docs.nvidia.com/metropolis/deepstream/dev-guide/text/DS_plugin_gst-nvinfer.html#gst-nvinfer-file-configuration-specifications)
|
|
|
|
* model-color-format
|
|
|
|
```
|
|
# 0=RGB, 1=BGR, 2=GRAYSCALE
|
|
model-color-format=0
|
|
```
|
|
|
|
**NOTE**: Set it according to the number of channels in the `cfg` file (1=GRAYSCALE, 3=RGB for Darknet YOLO) or your model configuration (ONNX).
|
|
|
|
* custom-network-config and model-file (Darknet YOLO)
|
|
|
|
* Example for custom YOLOv4 model
|
|
|
|
```
|
|
custom-network-config=yolov4_custom.cfg
|
|
model-file=yolov4_custom.weights
|
|
```
|
|
|
|
* onnx-file (ONNX)
|
|
|
|
* Example for custom YOLOv8 model
|
|
|
|
```
|
|
onnx-file=yolov8s_custom.onnx
|
|
```
|
|
|
|
* model-engine-file
|
|
|
|
* Example for `batch-size=1` and `network-mode=2`
|
|
|
|
```
|
|
model-engine-file=model_b1_gpu0_fp16.engine
|
|
```
|
|
|
|
* Example for `batch-size=1` and `network-mode=1`
|
|
|
|
```
|
|
model-engine-file=model_b1_gpu0_int8.engine
|
|
```
|
|
|
|
* Example for `batch-size=1` and `network-mode=0`
|
|
|
|
```
|
|
model-engine-file=model_b1_gpu0_fp32.engine
|
|
```
|
|
|
|
* Example for `batch-size=2` and `network-mode=0`
|
|
|
|
```
|
|
model-engine-file=model_b2_gpu0_fp32.engine
|
|
```
|
|
|
|
**NOTE**: To change the generated engine filename (Darknet YOLO), you need to edit and rebuild the `nvdsinfer_model_builder.cpp` file (`/opt/nvidia/deepstream/deepstream/sources/libs/nvdsinfer/nvdsinfer_model_builder.cpp`, lines 825-827)
|
|
|
|
```
|
|
suggestedPathName =
|
|
modelPath + "_b" + std::to_string(initParams.maxBatchSize) + "_" +
|
|
devId + "_" + networkMode2Str(networkMode) + ".engine";
|
|
```
|
|
|
|
* batch-size
|
|
|
|
```
|
|
batch-size=1
|
|
```
|
|
|
|
* network-mode
|
|
|
|
```
|
|
# 0=FP32, 1=INT8, 2=FP16
|
|
network-mode=0
|
|
```
|
|
|
|
* num-detected-classes
|
|
|
|
```
|
|
num-detected-classes=80
|
|
```
|
|
|
|
**NOTE**: Set it according to number of classes in `cfg` file (Darknet YOLO) or your model configuration (ONNX).
|
|
|
|
* interval
|
|
|
|
```
|
|
# Number of consecutive batches to be skipped
|
|
interval=0
|
|
```
|

### Testing the model
|
|
|
|
