使用教程

标注图片

你可以使用 网页标注工具 (备用地址) 将本地电脑上的图片标注。当完成标注后,可以通过EXPORT LABELS按钮导出xml标注(A zip package containing files in VOC XML Fomrat).

当你准备好训练数据后(训练数据是N张jpg图片和同名xml),将数据上传到远程GPU电脑上的train_data文件夹。

数据下载

如果github下载速度太慢了,可以试用这个百度网盘链接:https://pan.baidu.com/s/1UpAM06U9E2WzePm2JGqZhQ

服务器配置

如果jupyter让你选择kernel,建议选择 conda_mxnet_p36

在jupyter notebook上下载这个repo,并解压数据,可以在一个代码cell里输入下面的命令:

!git clone https://github.com/hetong007/d2l-1day-cv-hackathon.git
!cd d2l-1day-cv-hackathon && unzip images.zip

在jupyter notebook里安装 gluoncv,可以在一个代码cell里输入下面的命令:

!pip install --pre gluoncv

读数据时碰到报错内容含有Unspecified或者是int()等字样的,请安装最新版 gluoncv:

!pip install --pre gluoncv

如果遇到GPU is not enabled,说明你自己装了一个CPU版本的mxnet,把GPU版本的覆盖掉了,修复:

!pip install --pre --upgrade mxnet-cu100
