前言

官网文档指引：https://doc.sophgo.com/sdk-docs/v23.03.01/docs_latest_release/docs/SophonSDK_doc/zh/html/common_test/disclaimer.html
写的很好，真的很好，就是太太太太多多多多了。。。。

1.环境准备

算能盒子 se5 16路 芯片BM1684
开发机：ubuntu server 20.04 内存 32G CPU 8核心 硬盘：320G
1.安装docker
官网指引：https://docs.docker.com/engine/install/ubuntu/
官网的指引不全，没有设置开机自启，而且sdk3.0以后 算能官网不提供docker环境了。所以docker其实是非必选项。
安装docker

sudo apt-get install docker.io

更换国内镜像源
首先sudo mkdir /etc/docker文件夹
然后sudo vim /etc/docker/daemon.json
在里面添加如下内容：

sudo vim /etc/docker/daemon.json

{
 "registry-mirrors": ["https://registry.docker-cn.com"]
}

重载配置文件、重启docker服务

sudo systemctl daemon-reload
sudo service docker restart

配置开机自启

sudo systemctl enable docker

2.下载开发包sdk：
ref：https://developer.sophgo.com/site/index/material/35/all.html

我下载的是这个，05.01 也出来了，是0612更新的，我下载的时候最新版就是V23.03.01. 下载下来是这个(Release_230301-public.zip) 4.8 GB

安装包要准备两份，一份用于se5的固件升级，一份用于开发机的环境搭建，我的开发机没有芯片卡，所以用的是SOC模式。 一共三种工作模式：PCIe Mode、SoC Mode、arm_pcie Mode
3.刷机
略，照着文档刷机，准备sd卡和读卡器，将2的sdk放到读卡器，按照文档刷机
4.安装开发机环境
之前用的centos7.9 可是官方示例走的都是ubuntu，用起来非常不顺，而且在安装LIBSOPHON时第二步就出错了，所以换了ubuntu20.04系统。尽管它在这里提到可以用其它系统安装。
5.centos 上的报错（ubuntu的可以略过）

我是走的这里的时候报错的

报错的输出也贴出来，之前也有报错，根据报错安装插件就解决了，这个好像是libsophon内部自己的报错，搞不定，为了不浪费时间，又申请了一台ubuntu

2. 开发机安装环境

ref：https://doc.sophgo.com/sdk-docs/v23.03.01/docs_latest_release/docs/SophonSDK_doc/zh/html/sdk_intro/4_install.html#linux
参考3.4.1环境配置-linux
解压SDK压缩包

sudo apt-get install p7zip
sudo apt-get install p7zip-full
7z x Release_-public.zip
cd Release_-public

前两个要安装一下，否则会报错，可能是因为解压大文件吧，反正在centos上是遇到了。
上传的特别慢，耐心等待一下吧

所以干会别的吧，一会儿回来， 公司在bj，张家口的服务器，北京没资源了，唉…穷则战术穿插，没法火力压制啊！！

1.普通用户执行docker命令不用sudo的技巧
将这个普通用户进入docker组啊

# 创建docker用户组，若已有docker组会报错，没关系可忽略
sudo groupadd docker
# 将当前用户加入docker组
sudo gpasswd -a ${USER} docker
# 重启docker服务
sudo service docker restart
# 切换当前会话到新group或重新登录重启X会话

2.再次回到正题，将压缩包解压到tpu-nntc

cd tpu-nntc__
mkdir tpu-nntc
tar zxvf tpu-nntc_v--.tar.gz --strip-components=1 -C tpu-nntc

3.创建docker容器并进入Docker

cd tpu-nntc
#如果当前系统没有对应的镜像，会自动从docker hub上下载；此处将tpu-nntc的上一级目录映射到docker内的/workspace目录；这里用了8001到8001端口的映射（使用ufw可视化工具会用到端口号）。
#如果端口已被占用，请根据实际情况更换为其他未占用的端口。
docker run -v $PWD/..:/workspace -p 8001:8001 -it sophgo/tpuc_dev:latest

4.初始化软件环境

cd /workspace/tpu-nntc
source scripts/envsetup.sh

请注意，如果docker stop后重新进入，则需要重新source环境变量。

4.libsophon环境搭建

cd libsophon__
# 安装依赖库，只需要执行一次
sudo apt install dkms libncurses5
sudo dpkg -i sophon-*.deb
# 在终端执行如下命令，或者log out再log in当前用户后即可使用bm-smi等命令
source /etc/profile
