Vatic 使用记录

vatic docker ubuntu video labeling

在此输入正文

1. Ubuntu14.04 安装 docker

检查版本：docker只支持内核版本3.10以上的。
```
root$ uname -r
4.4.0-31-generic # 满足要求
```

添加docker源

root$ echo "deb https://apt.dockerproject.org/repo ubuntu-trusty main" > /etc/apt/sources.list.d/docker.list
  root$ apt-get update

搜索并安装docker-engine

root$ apt-cache search docker
  docker - System tray for KDE3/GNOME2 docklet applications
  kdocker - lets you dock any application into the system tray
  docker.io - Linux container runtime
  golang-docker-dev - Externally reusable Go packages included with Docker
  vim-syntax-docker - Docker container engine - Vim highlighting syntax files
  root$ apt-get install docker-engine
Setting up docker-engine (17.05.0~ce-0~ubuntu-trusty) ...

检查docker版本

root$ docker version
Client:
Version:      17.05.0-ce
API version:  1.29
Go version:   go1.7.5
Git commit:   89658be

OS/Arch:      linux/amd64
Server:
Version:      17.05.0-ce
API version:  1.29 (minimum version 1.12)
Go version:   go1.7.5
Git commit:   89658be

检查docker是否正常安装

root$ docker run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
  (amd64)
3. The Docker daemon created a new container from that image which runs the
  executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
  to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

检查当前运行的镜像列表

root$ docker ps -a
CONTAINER ID        IMAGE                                 COMMAND             CREATED              STATUS                          PORTS                  NAMES
6842f46ad9a4        hello-world                           "/hello"            About a minute ago   Exited (0) About a minute ago                          vigorous_elion

停止并删除指定的镜像

root$ docker stop 6842f46ad9a4
  6842f46ad9a4
  root$ docker rm 6842f46ad9a4
6842f46ad9a4

2. 使用 Vatic docker

拉取最新的镜像：共享视频数据目录

root$ DATA_DIR=/home/yf/Desktop/SOD-codes/vatic/data  # 指定输出目录
  root$ docker run -it -p 8080:80 -v /path/to/data/in:/home/vagrant/vagrant_data jldowns/vatic-docker-contrib:latest

root@70ad25a4acd9$ pwd   # 已经进入容器
/home/vagrant

开启MySQL和Apache服务

root@70ad25a4acd9$ sh start_services.sh
* Starting MySQL database server mysqld                                               [ OK ] 
* Checking for tables which need an upgrade, are corrupt or were 
not closed cleanly.

提取视频帧：注意vatic默认将宽度resize到720。

root@70ad25a4acd9$ cd vatic && pwd
  /home/vagrant/vatic

开始标注：从浏览器打开链接，注意在链接中加入端口8080，如：http://localhost:8080/?id=1&hitId=offline

输出标注文件

root@70ad25a4acd9$ turkic dump job_id -o ../vagrant_data/anno.txt

可视化标注结果

root@70ad25a4acd9$ turkic visualize 0 ../vagrant_data/tmp --merge --no-augment --renumber --labels
  root@70ad25a4acd9$ ffmpeg -f image2 -i ../vagrant_data/tmp/%d.jpg -vcodec libx264 -r 30 ../vagrant_data/out.mp4

3. docker 退出重连

root$ docker ps -a
root$ docker start $job_id
root$ docker attach $job_id
