网上教程一大堆，这个没啥说的
下载RKNN SDK
https://wiki.t-/zh_CN/ROC-RK3568-PC/usage_npu.html
RKNN SDK 为带有 NPU 的 RK3566/RK3568 芯片平台提供编程接口，能够帮助用户部署使用 RKNN-Toolkit2 导出的 RKNN 模型
复制librknn_api支持
运行命令
sudo cp RK_NPU_SDK_1.2.0/release/rknpu2/runtime/RK356X/Linux/librknn_api/aarch64/* /usr/lib
复制
RK_NPU_SDK_1.2.0/release/rknpu2/runtime/RK356X/Linux/librknn_api/aarch64/librknn_api.soRK_NPU_SDK_1.2.0/release/rknpu2/runtime/RK356X/Linux/librknn_api/aarch64/librknnrt.so
到
/usr/lib
下载运行示例
rknn算子查询1.3
/rockchip-linux/rknn-toolkit2
它会报错，问题不大，信息如下
解决方法：把图片换成640×640，或者cv2.resize（640×640）

修改后运行结果如下：
模型转换paddle---->onnx------>rknn
paddle---->onnx
前置条件，已导出推理模型
paddle.jit.save(model, args.infer_save_dir)
在aistudio上

我转换的，paddle2onnx命令，最低就只能是V7
需要的V6

先看环境中有没有
find / -name libpython3.6m.so.1.0
有则复制
sudo cp /usr/local/python36/lib/libpython3.6m.so.1.0 /usr/local/lib64/sudo cp /usr/local/python36/lib/libpython3.6m.so.1.0 /usr/lib/ sudo cp /usr/local/python36/lib/libpython3.6m.so.1.0 /usr/lib64/
没有就重新编译安装，安装后查看环境中有没有，有则复制

解决方法
下载protobufv3.0.0，点击download zip，不要用git clone
下载gmock-1.7.0
版本一定要对齐
把gmock解压出来的目录拷贝到protobuf目录下，改名为gmock，目录结构如下：
cd protobuf
vim aotogen.sh将删掉以下部分代码，禁用自动下载，已经手动下载好了:
if test ! -e gmock; thenecho "Google Mock not present. Fetching gmock-1.7.0 from the web..."curl -O /files/gmock-1.7.0.zipunzip -q gmock-1.7.0.ziprm gmock-1.7.0.zipmv gmock-1.7.0 gmockfi
安装protobuf，分别执行以下代码
./autogen.sh./configuremakemake checkmake install
配置libprotobuf.conf
sudo vim /etc/ld.so.conf.d/libprotobuf.conf 包含内容：/usr/local/libsudo ldconfig
验证是否安装成功，查看版本号
~$ protoc --version ~$ libprotoc 3.0.0
