orangepi-5b 使用 rknn-toolkit2 实测
主机环境：ubuntu20.04 x86_64
开发板 orangepi-5b 4G ram 32G emmc
网站介绍 http://www.orangepi.cn/html/hardWare/computerAndMicrocontrollers/details/Orange-Pi-5B.html
基于rk3588s
所以我们使用 rknn-toolkit2
step1 配置交叉编译工具链：
下载地址 https://releases.linaro.org/components/toolchain/binaries/
bash
### CROSS-COMPILE
export AARCH64_LINUX_GNU_TOOLS=/media/wmx/cross_compile_tools/aarch64-linux-gun/gcc-x86_64_aarch64-linux-gnu/bin
export ARM_LINUX_GNUEABI_TOOLS=/media/wmx/cross_compile_tools/arm-linux-guneabi/gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabi/bin/
export ARM_LINUX_GNUEABIHF_TOOLS=/media/wmx/cross_compile_tools/arm-linux-guneabihf/gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabihf/binstep2 下载工具RKNN-Toolkit2
github 组织 airockchip
https://github.com/airockchip
下载 https://github.com/airockchip/rknn-toolkit2
不兼容：
RKNN-Toolkit2 is not compatible with RKNN-Toolkit
版本对应：
Ubuntu 18.04 python 3.6/3.7
Ubuntu 20.04 python 3.8/3.9
Ubuntu 22.04 python 3.10/3.11
Latest version:v2.0.0-beta0
我下载的是v2.0.0-beta0 版本
/media/wmx/ws1/ai/rk/rknn-toolkit2-2.0.0-beta0
step3 在这个目录下创建虚拟环境venv：
/media/wmx/ws1/ai/rk/rknn-toolkit2-2.0.0-beta0
bash
conda create --prefix ./venv python=3.9
conda activate ./venv/
#安装依赖：
python -m pip install -r rknn-toolkit2/packages/requirements_cp39-2.0.0b0.txt -i https://mirror.baidu.com/pypi/simple
#安装软件包
python -m pip install rknn-toolkit2/packages/rknn_toolkit2-2.0.0b0+9bab5682-cp39-cp39-linux_x86_64.whl -i https://mirror.baidu.com/pypi/simple 验证是否安装成功:
python
python
from rknn.api import RKNN没有报错，ok
step4 下载demo
https://github.com/airockchip/rknn_model_zoo
路径：
/media/wmx/ws1/ai/rk/rknn_model_zoo-2.0.0
step5 下载模型并且转换
激活的虚拟环境venv 命令行切换到目录：
bash
cd /media/wmx/ws1/ai/rk/rknn_model_zoo-2.0.0/examples/yolov5/model
# 下载模型
chmod +x download_model.sh
./download_model.sh
# 转换onnx 模型到 rknn
cd ../python
python convert.py ../model/yolov5s_relu.onnx rk3588step6 编译示例yolo5
切换到 /media/wmx/ws1/ai/rk/rknn_model_zoo-2.0.0
修改build-linux.sh 配置交叉编译工具
AARCH64_LINUX_GNU_TOOLS是step1配置的环境变量
bash
export GCC_COMPILER=$AARCH64_LINUX_GNU_TOOLS/aarch64-linux-gnu
bash
cd /media/wmx/ws1/ai/rk/rknn_model_zoo-2.0.0
./build-linux.sh -t rk3588 -a aarch64 -d yolov5step7 push 到板子上运行
/home/orangepi/workspace 是开发板上面已经创建的目录
bash
adb push install/rk3588_linux_aarch64/rknn_yolov5_demo/ /home/orangepi/workspace先ssh到板子上
或者adb shell到板子上
板子上面执行的效果输出 out.png：
bash
orangepi@orangepi5b:~/workspace/rknn_yolov5_demo$ sudo ./rknn_yolov5_demo ./model/yolov5.rknn ./model/bus.jpg
