前言
实验室的项目需要用到Firefly的AIO-3399 ProC开发板,该型号开发板集成了硬件加速芯片NPU(神经网络加速单元),经tensorflow、PyTorch等训练好的模型可用官方提供的RKNN Toolkit工具转换为.rknn格式的模型,运行在开发板上利用NPU进行对数据的后向推理加速处理。RKNN Toolkit开发套件安装繁琐,前前后后折腾了一周的时间才算部署成功,故记录下部署过程及遇到的问题,以供自己和各位参考。 一、开发部署环境 [tr]开发环境软件版本/配置[/tr]
1、RKNN-Toolkit → 基于 Python 环境的模型转换推理开发工具 2、DRV → NPU 和上位机通信的服务 3、API → 调用NPU 硬件的 API 接口 三、安装过程 3.1 查看开发板中DRV的版本(1.3.1) firefly@firefly:~$ dpkg -l | grep 3399pro ii firefly-3399pronpu-driver 1.3.1 arm64 更新DRV的版本 sudo apt update sudo apt install firefly-3399pronpu-driver 更新完后,检查DRV的版本已升级至1.6.0 firefly@firefly:~$ dpkg -l | grep 3399pro ii firefly-3399pronpu-driver 1.6.0 arm64 3.2 关闭开发板当前系统的图形界面 使用Xshell 6 SSH登录开发板,进行下列操作,防止后续编译软件包时因系统内存不足导致编译失败 (谨慎使用,最新固件AIO-RK3399PROC-UBUNTU-20210304-1705.img关闭图形界面后会导致系统无法启动,串口显示如下报错信息: 4189 串口[ 4.772713] 00000040: 000002a5 000002a5 00000000 00000000 00000000 00000000 00000000 00000000 4190 串口[ 4.773490] 00000060: 00000004 00000004 00000753 00000753 00000000 00000000 00000000 00000000 4191 串口[ 4.774254] 00000080: 00000000 00000000 4192 串口[ 4.820522] ---[ end Kernel panic - not syncing: Attempted to kill init! exitcode=0x00007f00 4193 串口[ 4.820522] 4194 串口DDR Version 1.24 20191016 AIO-RK3399PROC-UBUNTU18.04-GPT-20200525-1016.img该版本可以正常操作) sudo systemctl set-default multi-user.target sudo reboot #未关GUI界面时的系统占用 Memory usage: 12 % of 1893MB Usage of /: 24% of 15G #关闭GUI界面时的系统占用 Memory usage: 4 % of 1893MB Usage of /: 24% of 15G (PS:待RKNN Toolkit安装完成后可再手动开启用户界面 sudo systemctl set-default graphical.target sudo reboot 3.3 安装Python3.7 sudo apt update #检查可更新文件 sudo apt install software-properties-common #安装可添加源的工具 sudo add-apt-repository ppa:deadsnakes/ppa #添加源,否则会无法找到python3.7-dev软件包 sudo apt install python3.7-dev #安装python3.7 3.4 用virtualenv管理python版本 (开发板系统中同时存在多个 Python(Python2.7&python3.6)版本,建议使用 virtualenv来管 理 Python环境) #创建 virtualenv环境 sudo apt install virtualenv #安装virtualenv软件 virtualenv -p /usr/bin/python3.7 venv #创建虚拟环境 source venv/bin/activate #激活venv环境 (venv) firefly@firefly:~$ pip3 -V #查看当前pip3所在Python的路径 pip 21.0.1 from /home/firefly/venv/lib/python3.7/site-packages/pip (python 3.7)pip 修改python默认为python3.7: 为了因为C++调用python时,默认是调用python2.7,这导致很多python3.7的语法报错。所以需要更改python默认软连接 #查看路径python,python3.7路径 which python python3.7 /usr/bin/python /usr/bin/python3.7 sudo rm /usr/bin/python sudo rm /usr/bin/python3 #创建python3.软连接到python&Python3 sudo ln -s /usr/bin/python3.7 /usr/bin/python sudo ln -s /usr/bin/python3.7 /usr/bin/python3 至此Python3.7环境配置完成。 3.5 安装相关依赖包(numpy、h5py &opencv) 3.5.1 安装并更新相关依赖包 sudo apt-get update sudo apt-get install cmake gcc g++ libprotobuf-dev protobuf-compiler sudo apt-get install liblapack-dev libjpeg-dev zlib1g-dev pip3 install --upgrade pip #更新pip包的版本 pip3 install wheel setuptools #安装 Python 打包工具 3.5.2 安装并编译numpy、h5py (PS:opencv-python和h5py同时依赖的numpy包的版本必须是1.16.3,故需先安装编译numpy包。较难编译和费时较长的whl包已上传至网盘,如有需要,可从文末的链接下载到PC端,通过Xftpd软件上传至开发板安装目录,离线安装即可 ) 重要 :安装包的顺序不可调换,否则默认安装的依赖包版本与RKNN所要求的冲突 执行以下命令: pip3 install numpy==1.16.3 #安装numpy包,编译完成即可进行下一步 #或将离线包下载后安装 #pip3 install numpy-1.16.3-cp37-cp37m-linux_aarch64.whl pip3 install h5py==2.8.0 -i https://pypi.tuna.tsinghua.edu.cn/simple #安装h5py包,编译完成即可进行下一步 这时编译h5py包报错 /tmp/pip-install-g8zeu2wp/h5py_e742916510854ca6b68f847f94f04c44/h5py/api_compat.h:27:10: fatal error: hdf5.h: No such file or directory #include "hdf5.h" ^~~~~~~~ compilation terminated error: command 'aarch64-linux-gnu-gcc' failed with exit status 1 ---------------------------------------- ERROR: Command errored out with exit status 1: 需执行以下操作,安装缺少的依赖包,重新编译h5py sudo apt-get install libhdf5-devpip3 install h5py==2.8.0 -i https://pypi.tuna.tsinghua.edu.cn/simple#或将离线包下载后安装h5py#pip3 install h5py-2.8.0-cp37-cp37m-linux_aarch64.whl 3.5.3 安装并编译opencv-python 安装并编译opencv-Python包,如果不指定版本,默认会从清华源下载已编译好的最新版本包opencv_python-4.5.1.48-cp37-cp37m-manylinux2014_aarch64.whl (34.5 MB),但该包默认依赖numpy的版本要求numpy>=1.19.3,RKNN Toolkit依赖的numpy版本必须是1.16.3,所以不可安装最新版本的opencv_python-4.5.1.48版本,需下载4.3.0.38版本的opencv-python源码包编译 pip3 install opencv-python==4.3.0.38 -i https://pypi.tuna.tsinghua.edu.cn/simple --default-timeout=200 #安装源码包进行编译 [2021/ 21:43:23] Building wheels for collected packages: opencv-python ...

五、总结
不同平台,RKNN提供的基于不同Python版本的安装包,安装时不同平台对应的依赖关系需要处理好,具体如下: 1.Windows只提供 Python3.6的安装包。 2. MacOS提供 python3.6和 python3.7的安装包。 3. ARM64平台(安装 Debian 9或 10操作系统)提供 Python3.5( Debain 9)和 Python3.7(Debian10)的安装包。 4. Linux_x64平台提供基于 python3.5和 python3.6的安装包。 5.开发板编译好的whl包一般会存放在/.cache/pip/wheels/路径下,可将这些包导出保存。 Building wheel for onnx (setup.py) ... done Created wheel for onnx: filename=onnx-1.6.0-cp37-cp37m-linux_aarch64.whl s Stored in directory: /home/firefly/.cache/pip/wheels/... cp -ri ./wheel* /home/firefly /home/firefly
sudo rm -rf ~/.cache/pip #删除pip3缓存文件 source /home/firefly/venc/bin/activate #进入venc环境 #加速Python pip安装速度,更改Python软件源,操作方法: pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple pip install pip -U #RKNN启动可视化窗口命令 python3 -m rknn.bin.visualization #打印内核调试信息 cat /proc/kmsg dmesg | grep ov13850 #查看ov13850驱动是否正常 cd /usr/local/bin/ #相机测试脚本路径 ls /dev/video #列出设备挂载到video节点信息 v4l2-ctl -D #列出摄像头的驱动信息 v4l2-ctl -d /dev/video0 --list-formats-ext #列出视频节点设备所支持的视频格式,分辨率 v4l2-ctl --list-devices #列出视频设备挂载节点信息 部署过程中生成的whl包和下载的yolov3.weights文件如有需要可在下面链接自取,因为每个人的开发环境不同,相应的whl包不保证都能正常使用,对应的whl包仅可在RKNN1.6.0,python3.7环境下安装使用。 |
