RKNN Toolkit Lite 的文件目录在 SDK/external/rknn-toolkit/rknn-toolkit-lite/rknn-toolkit-lite-v1.7.0.dev_0cfb22
或者直接使用 git 拉取代码：git clone

-b rv1126_rv1109/firefly

测试环境使用 RV1126 主机。文件系统是 Firefly Debian10。以下操作均 RV112 上执行。

Firefly Debian10 固件 RKNN Toolkit Lite 安装步骤：

一、 安装依赖 numpy / psutils / ruamel.yaml

如果没有装 pip3 ，请先用 sudo apt-get update && sudo apt-get install python3-pip 装下

pip3 install numpy==1.16.3
pip3 install psutil==5.6.2
pip3 install ruamel.yaml==0.15.81

二、 安装 opencv-python 。用 pip3 安装会一直失败，所以直接在网上下载包。

先装以下依赖， wget 用到的两个 deb 包已经放在 rknn-toolkit-lite-v1.7.0.dev_0cfb22/requires/ 目录下

sudo apt-get install multiarch-support
wget

sudo dpkg -i libjasper1_1.900.1-debian1-2.4+deb8u6_armhf.deb
wget

sudo dpkg -i libjasper-dev_1.900.1-debian1-2.4+deb8u6_armhf.deb
sudo apt-get install libhdf5-dev
sudo apt-get install libatlas-base-dev
sudo apt-get install libqtgui4
sudo apt-get install libqt4-test
pip3 install rknn-toolkit-lite-v1.7.0.dev_0cfb22/requires/opencv_python-4.0.1.24-cp37-cp37m-linux_armv7l.whl

三、安装 RKNN Toolkit Lite

使用以下命令安装RKNN Toolkit Lite

pip3 install rknn-toolkit-lite-v1.7.0.dev_0cfb22/packages/rknn_toolkit_lite-1.7.0.dev_0cfb22-cp37-cp37m-linux_armv7l.whl

四、跑 example

cd rknn-toolkit-lite-v1.7.0.dev_0cfb22/examples-lite/inference_with_lite
python3 test.py

结果输出如下：

结果输出如下：

root@firefly:/home/firefly/rknn-toolkit-lite-v1.7.0.dev_0cfb22/examples-lite/inference_with_lite# python3 test.py
--> list devices:

None devices connected.
