【摘要】 Atlas 200 DK安裝python的hiai庫以及opencv
【昇騰】開發板上安裝python的hiai庫和opencv庫
Matrix是已經支持phthon接口了，但是發現目前python的hiai庫並沒有自動安裝，需要自己安裝；
話不多說下面是安裝步驟：
步驟1. 開發板聯網，如果已聯網則跳過該步驟；
否則請參考以下鏈接配置開發板聯網（https://bbs.huaweicloud.com/forum/thread-26546-1-1.html ）
接下來需要在開發板上配置arm的源（編輯/etc/apt/sources.list內容替換爲如下中科大的源或者清華的源）；
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
清華源：
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
更換源以後注意執行：sudo apt-get update
步驟2. 安裝依賴以及hiai庫
a) 安裝依賴
（如果apt-get沒有sudo權限請配置：在/etc/sudoers中HwHiAiUser的權限配置一行最後添加：/usr/bin/apt-get）
（如果保存不了，保存時用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) 下載python2_hiai_install.sh
wget https://gitee.com/Atlas200DK/sample-classification-python/raw/master/scripts/python2_hiai_install.sh
c)安裝hiai庫（需要再root用戶下）
su
bash python2_hiai_install.sh
步驟3. 安裝opencv
sudo apt-get install python-opencv
4. 檢查，登錄開發板以後在python下分別執行如下import，不報錯則說明hiai和opencv均已經完成安裝，可以愉快的玩耍嘍：
import hiai
import cv2
