嘉楠勘智k230开发板上手记录(五)

虽然没有找到hhb的官方示例，但是我找到了nncase的，在src/big/nncase/examples中

一、环境搭建

examples也有个readme，不过里面的环境搭建跟sdk中的有点差别，不过大差不差，docker容器已经启动了，需要在容器中安装nncase

cd /root/k230/k230_sdk-main/src/big/nncase/
pip install x86_64/*.whl
pip install nncase-kpu==2.2.0.20230728

虽然x86_64中提供的whl是2.1版本的，但是安装会自动下载2.2版本的安装

二、编译模型--CMakeList

移动到examples下

1. 生成kmodel模型

python3 ./scripts/yolov5s_onnx.py --target k230 --model  --dataset calibration_dataset

2. 验证生成的kmodel模型精度

export PATH=$PATH:/usr/local/lib/python3.8/dist-packages/
python3 scripts/yolov5s_onnx_simu.py  --model  --model_input object_detect/data/input_fp32.bin  --kmodel tmp/yolov5s_onnx/test.kmodel --kmodel_input object_detect/data/input_uint8.bin

3. 编译

./build_app.sh

可以在k230_bin下有可执行文件

三、用Makefile

前两步跟上面一样。另外希望官方可以出个Makefile的教程，我是参考CMakeList生成的写的Makefile

3. 新建一个文件Makefile

TARGET_CLASSIFY := image_classify.elf# 指定交叉编译器

k230_sdk := /root/k230/k230_sdk-main
# set opencv

clean:@echo "test1"rm -rf $(BUILD_DIR_OBJECT) $(BUILD_DIR_CLASSIFY)create_build:mkdir -p $(BUILD_DIR_OBJECT)mkdir -p $(BUILD_DIR_CLASSIFY)

注意 --static &< 一定要在前面，不然会出错。具体原因参考 gcc（g++）编译的顺序问题_Sunny04的博客-CSDN博客

，按照这篇博客的说法，越是底层的库，越是往后面写，例如-lopencv_imgcodecs -lopencv_imgproc，opencv_imgcodecs有调用opencv_imgproc中的函数，两个顺序乱掉就会出现undefined reference to的错误

4. 写个build_makefile_app.sh

#!/bin/bash# 将脚本中的每一行命令在执行之前打印出来
set -x# set cross build toolchain
make clean
makek230_bin=build/k230_bin
mkdir -p ${k230_bin}if [ -f build/image_classify/image_classify.elf ]; thenimage_classify=${k230_bin}/image_classifyrm -rf ${image_classify}cp -a image_classify/data/ ${image_classify}cp build/image_classify/image_classify.elf ${image_classify}cp tmp/mbv2_tflite/test.kmodel ${image_classify}
fiif [ -f build/object_detect/object_detect.elf ]; thenobject_detect=${k230_bin}/object_detectrm -rf ${object_detect}cp -a object_detect/data/ ${object_detect}rm ${object_detect}/*.bincp build/object_detect/object_detect.elf ${object_detect}cp tmp/yolov5s_onnx/test.kmodel ${object_detect}
