【昇腾】【玩转Atlas200DK系列】Atlas 200 DK安装python2的hiai库以及opencv

【昇腾】开发板上安装python2的hiai库和opencv库

Matrix是已经支持phthon接口了，但是发现目前python的hiai库并没有自动安装，需要自己安装；

话不多说下面是安装步骤：

步骤1. 开发板联网，如果已联网则跳过该步骤；

          否则请参考以下链接配置开发板联网（https://bbs.huaweicloud.com/forum/thread-26546-1-1.html ）

           接下来需要在开发板上配置arm的源（编辑/etc/apt/sources.list内容替换为如下中科大的源或者清华的源）；

中科大源
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-backports main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-proposed main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-security main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-updates main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-backports main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-proposed main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-security main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-updates main multiverse restricted universe

清华源：

deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ xenial-security main multiverse restricted universe
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ xenial-updates main multiverse restricted universe
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ xenial-backports main multiverse restricted universe
deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe
deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ xenial-security main multiverse restricted universe
deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ xenial-updates main multiverse restricted universe
deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ xenial-backports main multiverse restricted universe

                 更换源以后注意执行：sudo apt-get update

步骤2. 安装依赖以及hiai库

    a) 安装依赖

（如果apt-get没有sudo权限请配置：在/etc/sudoers中HwHiAiUser的权限配置一行最后添加：/usr/bin/apt-get）

（如果保存不了，保存时用wq！保存即可）

        sudo apt-get install python-setuptools python-dev build-essential python-pip

        pip install numpy==1.16.0 enum34==1.1.6 future==0.17.1 funcsigs==1.0.2

    b) 下载python2_hiai_install.sh

        wget   https://gitee.com/Atlas200DK/sample-classification-python/raw/master/scripts/python2_hiai_install.sh

    c)安装hiai库（需要再root用户下）

            su

            bash python2_hiai_install.sh

步骤3. 安装opencv

            sudo apt-get install python-opencv

4. 检查，登录开发板以后在python下分别执行如下import，不报错则说明hiai和opencv均已经完成安装，可以愉快的玩耍喽：

            import hiai

            import cv2
