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

1. 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。
2. 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。
3. 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。
4. 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

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

E: Sub-process /usr/bin/dpkg returned an error code (1)

# 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

[global]
#以华为源为例，请根据实际情况进行替换。
index-url = https://mirrors.huaweicloud.com/repository/pypi/simple
trusted-host = mirrors.huaweicloud.com
timeout = 120

# 软连接
su
ln -s /usr/local/python3.7.5/bin/python3 /usr/local/python3.7.5/bin/python3.7.5
ln -s /usr/local/python3.7.5/bin/pip3 /usr/local/python3.7.5/bin/pip3.7.5
exit

# python 环境变量
vim .bashrc

# 修改之后使之生效
source .bashrc

#用于设置python3.7.5库文件路径
export LD_LIBRARY_PATH=/usr/local/python3.7.5/lib:$LD_LIBRARY_PATH
#如果用户环境存在多个python3版本，则指定使用python3.7.5版本
export PATH=/usr/local/python3.7.5/bin:$PATH

# 安装依赖

安装软件

# 给 downloads 目录添加权限
cd downloads
# chmod +x A*
su
chown -R HwHiAiUser:HwHiAiUser ./

# 驱动用 root 装
su
./A300-3010-npu-driver_20.2.0_ubuntu18.04-x86_64.run --full

## 替换原来的 再重启
reboot

# 其他用 HwHiAIUser 安装
./Ascend-cann-nnrt_3.3.0.alpha001_linux-x86_64.run --install
# 环境变量配置 41‘50

# 安装 toolkit
./Ascend-cann-toolkit_3.3.0.alpha001_linux-x86_64.run --install

## 注意保持环境变量配置 45‘47
## 有三组： 离线推理、在线推理、模型转换

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！
