昇腾CANN开发&;运行环境搭建

大家好，我是Copy攻城狮，有幸参加了【昇腾CANN训练营】。昇腾CANN训练营包含一营（应用开发营）、二营（模型开发营）、三营（算子开发营），每营分别开设3节课程，共计9节课程。今天是和一营长学习【昇腾CANN开发&运行环境部署】，谨以此文记录一下学习过程。

目标

开通 AIECS 并升级环境

安装驱动

安装 nnrt

安装 Toolkit

安装 MindStudio

跑通 MindStudio 模板APP之ResNet50

坑点

MindStudio 运行依赖特定的环境，因此网页版的 CloudShell 和 本地的 Xshell 都不能成功调起 MindStudio 界面，按照老师的教程，可以使用MobaXterm。

推荐使用默认的 HwHiAIUser 用户，但需留意有些过程需要使用 root 用户，比如驱动的安装。

各种环境变量配到吐血，稍不留意就会掉入深坑中；此外在安装 Toolkit 时如果遇到终端窗口意外退出之后，可尝试先卸载再重新安装。

一定要留意 HwHiAiUser 的权限，在安装 MindStudio 时也需文件读写的权限。

流水

时间如流水，学习完再操作完到简单记录流水账，就差不多可以遇见凌晨4点的羊城了……

此处记录方便自己后续查阅。

AIECS 开通

值得留意的是规格选 AI加速型,AI加速型实例提供AI芯片，主要用于机器视觉、图像分类、语音识别等AI推理场景,此次用单片的 Ascend 310；系统选用的Ubuntu 18.04 server 64bit for Ai1s(40GB)，当然还需绑定一个公网IP，让我们在本地通终端工具能够访问到ECS。

账号准备

登录修改HwHiAiUser 密码

cat /etc/passwd # （推荐）如果创建的运行用户是HwHiAiUser，其为CANN软件包的默认运行用户，在安装时无需指定该运行用户 passwd HwHiAiUser # (按需)修改sh --> bash vim /etc/passwd

资源下载

基本上昇腾相关的资料都可以通过访问 ascend.huawei.com 获取，因此我们要下载的驱动、工具也可以在昇腾官网上找到。

驱动

上文我们已经选用了昇腾310的环境，因此我们需要按照场景二来安装环境。 驱动选用的是Atlas300 3010 X86 Ubuntu18.04驱动包。

工具

安装x86平台开发套件软件包及x86平台推理引擎软件包。

软件

修改 apt 源

一切为了加速，一切使用镜像！

cd /etc/apt ll cp sources.list sources.list.bak vim sources.list # :%d

## 中科大源 ## 先备份源文件 deb https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universe multiverse deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universe multiverse deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse

apt-get update

安装依赖

依赖的安装也并非一帆风顺，遇到一些错误中断了安装，需要重新安装一下 python： apt-get install python3.7。当前环境只支持特定版本的Python。

参考开发者文档: https://support.huaweicloud.com/instg-cli-cann330/atlasrun_03_0033.html

sudo apt-get install -y gcc g++ make cmake zlib1g zlib1g-dev libbz2-dev libsqlite3-dev libssl-dev libxslt1-dev libffi-dev unzip pciutils net-tools libncursesw5-dev

# 解决 apt-get install python3.7 # 再重新执行安装

配置 pip 源

# 安装python 依赖 exit # 退回到HwHiAIUser cd ~/.pip vi pip.conf

# 解压mindstudio tar zxvf MindStudio_2.0.0-beta3_linux.tar.gz # 运行 mindstudio/bin/mindstudio.sh

遇到错误按照提示操作，先用root权限安装写apt依赖；再用HwHiAiUser安装python依赖。

sudo apt-get -y install xterm firefox xdg-utils openjdk-8-jdk fonts-droid-fallback fonts-wqy-zenhei fonts-wqy-microhei fonts-arphic-ukai fonts-arphic-uming gnome-keyring && /usr/local/python3.7.5/bin/pip3 install --user coverage gnureadline pylint matplotlib pandas absl-py

MindStudio端操作

最后

记得截图保存留念并删除资源！

晚安！
