虚拟环境搭建
首先在PC的ubuntu系统安装虚拟环境:
我的服务器是ubuntu18.04版本,所以安装python3.6
conda create -n ok3588 python=3.6
需要键盘输入y,然后完成虚拟环境安装。
其他系统的对应关系:
Ubuntu 18.04 python 3.6 / Ubuntu 20.04 python 3.8 / Ubuntu 22.04 python 3.10
软件包安装
进入虚拟环境
conda activate ok3588
首先安装正确的pip版本
curl https://bootstrap.pypa.io/pip/3.6/get-pip.py | python -
下载github 项目
git clone https://github.com/rockchip-linux/rknn-toolkit2
cd rknn-toolkit2/doc
pip install -r requirements_cp36-1.5.0.txt -i https://mirror.baidu.com/pypi/simple
cd rknn-toolkit2/packages
pip install rknn_toolkit2-1.5.0+1fa95b5c-cp36-cp36m-linux_x86_64.whl文章来源:https://www.toymoban.com/news/detail-601441.html
在PC机上运行yolov5目标检测
cd rknn-toolkit2/examples/onnx/yolov5
python test.py
