====== NPU Applications ======

===== Get Source Code =====

Clone the source code form our [[gh>khadas/edge2-npu]].

```shell
$ git clone https://github.com/khadas/edge2-npu
```

There are two types of application source code in C++ and Python.

===== Python Applications =====

Enter Python directory,

```shell
$ cd Python
```

Install dependences,

```shell
$ sudo cp ../C++/runtime/librknn_api/aarch64/librknnrt.so /usr/lib
$ sudo apt update
$ sudo apt install -y python3-dev python3-pip python3-opencv python3-numpy
$ pip3 install ./wheel/rknn_toolkit_lite2-1.3.0-cp310-cp310-linux_aarch64.whl
```

Take yolov5 as an example, other demos are similar.

```shell
$ cd resnet18
$ python3 resnet18.py

===== C++ Applications =====

Enter C++ directory, take yolov5 as an example.

Install dependences.

```shell
$ sudo apt update
$ sudo apt install cmake libopencv-dev
```

Complie and Run

```shell
# Yolov5
# Compile
$ cd yolov5
$ bash build.sh

# Run
$ cd install/yolov5
$ ./yolov5 data/model/yolov5s-640-640.rknn data/img/bus.jpg

# Yolov5_cap
# Compile
$ cd yolov5_cap
$ bash build.sh

# Run
$ cd install/yolov5
$ ./yolov5 data/model/yolov5s-640-640.rknn 33
```

''33'' is the index of camera.
