本文主要是介绍ONNX @riscv+OpenKylin，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
安装onnxruntime-riscv
下载软件:
git clone https://github.com/ucb-bar/onnxruntime-riscv
apt install unzip
cd onnxruntime-riscv && sh build.sh
报错...
改了g++环境变量部分还是不行，放弃。
安装onnxruntime
使用这个库
git clone https://github.com/zhangwm-pt/onnxruntime
因为刚开始报错需要cmake>3.25 ,所以去Download CMake
下载了3.28安装，但是configure的时候报错，所以放弃升级cmake，改切onnxruntime到2.6
git switch 2.6export MAX_JOBS=64sh build.sh --allow_running_as_root第一次需要加上--allow_running_as_root,后面再build就不需要了。
还学到用这个增加编译速度，不管是否有用，先存着
export makeflags=-j64
export MAKEFLAGS=-j64使用编译好的onnxruntime包@python3.10
创建python3.10环境,
设置多版本并存
下载pip软件：curl -sS https://bootstrap.pypa.io/get-pip.py | python3.10
使用编译好的onnxruntime包@python3.11
安装3.11python环境
apt install python3.11设置多版本并存
update-alternatives --install /bin/python3 python3 /bin/python3.8 1
update-alternatives --install /bin/python3 python3 /bin/python3.10 2
update-alternatives --install /bin/python3 python3 /bin/python3.11 3
使用这个命令切换：
update-alternatives --config python3
下载pip软件：curl -sS https://bootstrap.pypa.io/get-pip.py | python3.11
切换到3.11之后，安装311的包，其中onnx在这里下载： Releases · zhangwm-pt/onnxruntime · GitHub
具体地址：https://github.com/zhangwm-pt/onnxruntime/releases/download/riscv_whl_v2.9/onnxruntime-2.9.0-cp311-cp311-linux_riscv64.whl
onnx@飞桨
调试
build.sh报错
看build.sh内容，这三句存疑问
export CXX=riscv64-unknown-linux-gnu-g++
export CC=riscv64-unknown-linux-gnu-gcc
export CXXFLAGS="-march=rv64imafdc -mabi=lp64d"
修该成
export CXX=g++
export CC=gcc
export CXXFLAGS="-march=rv64imafdc -mabi=lp64d"
报错Could not find 'flake8' to check python scripts.

新库报错

CMake Error at CMakeLists.txt:5 (cmake_minimum_required):
CMake 3.26 or higher is required. You are running version 3.25.1
本来想安装cmake2.28的，但是编译太慢了，准备用onnx2.81 因为它用cmake3.24就行了。
切2.81 git checkout 2.8.1 怀疑没切成，因为还需要cmake>3.25
切2.6 git switch 2.6
cmake3.28configure报错

configure CMake with -DCMAKE_USE_OPENSSL=OFF to build without OpenSSL.
没事，不安装3.28了。
最终onnx本地没有编译成功，转而使用已编译好的包。已编译好的包只支持python3.10和3.11
onnx推理报错

降低Pillow版本解决 pip install Pillow==9.5.0
编译过程中到80%左右报错
/usr/bin/ld: libonnxruntime_common.a(threadpool.cc.o): in function `std::atomic<onnxruntime::concurrency::RunQueue<std::function<void ()>, onnxruntime::concurrency::ThreadPoolTempl<onnxruntime::Env>::Tag, 1024u>::ElemState>::compare_exchange_strong(onnxruntime::concurrency::RunQueue<std::function<void ()>, onnxruntime::concurrency::ThreadPoolTempl<onnxruntime::Env>::Tag, 1024u>::ElemState&, onnxruntime::concurrency::RunQueue<std::function<void ()>, onnxruntime::concurrency::ThreadPoolTempl<onnxruntime::Env>::Tag, 1024u>::ElemState, std::memory_order, std::memory_order)':

重新编译，报错变成

尝试 apt-get install libatomic-ops-dev
还是报错
切换到2.8版本，需要cmake升级到3.28
编译cmake3.28时报错：
make: 'cmake' is up to date.

configure CMake with -DCMAKE_USE_OPENSSL=OFF to build without OpenSSL.
尝试apt-get install libssl-dev
过了，bootstrap继续下去了。
make报错

这里过不去了，先搁置，准备用现成的包。
切换pip3.10和pip3.11后，都报错

解决方法：
curl -sS https://bootstrap.pypa.io/get-pip.py | python3.11
安装好onnx之后，运行报错：
