【CANN训练营】使用华为云开发者空间体验Sample仓实例体验

环境选择

前不久上了一次华为云开发者空间，发现华为云开发者空间里面有AI Notebook每天可以免费体验2小时910 B3的算力，这个对于需要学习掌握AscendC以及其他昇腾技能的小伙伴来说是个不错的福利，于是立马上手体验一下运行编译Sample仓算力是否正常。结果体验下来其实还是蛮好用的。原环境带的CANN版本是8.0的，这边体验选用了CANN8.3RC2的CANN版本，CANN包可以自己根据需要渠道http://www.hiascend.com 上根据需要下载新版本或者指定版本的CANN，这个还是比较方便的。

安装CANN

bash 复制代码

wget 'https://ascend-repo.obs.cn-east-2.myhuaweicloud.com/CANN/CANN%208.3.RC1/Ascend-cann-toolkit_8.3.RC1_linux-aarch64.run?response-content-type=application/octet-stream' -O Ascend-cann-toolkit_8.3.RC1_linux-aarch64.run

安装CANN

bash 复制代码

bash Ascend-cann-toolkit_8.3.RC1_linux-aarch64.run --full

激活环境

bash 复制代码

source /home/service/Ascend/ascend-toolkit/set_env.sh

开始体验

克隆Sample仓

bash 复制代码

git clone https://gitee.com/ascend/samples

编译算子工程（FrameworkLaunch方式）

进入AddCustom目录

bash 复制代码

cd samples/operator/ascendc/tutorials/AddCustomSample/FrameworkLaunch/AddCustom

修改CMakePresets.json文件

json 复制代码

"ASCEND_CANN_PACKAGE_PATH": {
                    "type": "PATH",
                    "value": "/home/service/Ascend/ascend-toolkit/latest" #此处修改为实际CANN路径
                },

进行算子工程编译

bash 复制代码

bash bulid.sh

部署算子

bash 复制代码

cd build_out
./custom_opp_openEuler_aarch64.run

运行样例算子

bash 复制代码

cd /mnt/workspace/samples/operator/ascendc/tutorials/AddCustomSample/FrameworkLaunch/AclNNInvocation
bash run.sh

输出结果
