Python SDK for DSDL

Project description

# DSDL-SDK 使用说明

## 1. 安装DSDL

python 环境3.8及以上 `bash python setup.py install `

## 2. Demo演示(COCO数据集可视化)

#### 2.1 解析器反序列化Yaml为Python代码 `bash dsdl parse --yaml demo/coco_demo.yaml `

#### 2.2 配置文件修改,设置读取路径

在`config.py`中,列举了所有支持的媒体文件读取方式,根据实际情况选择并配置文件路径等信息: a.本地读取: local_config`中的参数`working_dir`(本地数据所在的目录) b.阿里云OSS读取: `ali_oss_kwargs`中的参数(阿里云OSS的配置`access_key_secret, endpoint, access_key_id;桶名称`bucket_name`,数据在桶中的目录`working_dir`)

#### 2.3 可视化功能展示:

`bash python visualize.py -y <yaml-name>.yaml -c ali-oss -n 10 -r -v -f label bbox bool `

每个参数的意义为:

参数简写 | 参数全写 | 参数解释 |
——– | ————- | :———————————————————– |
-y | –yaml | dsdl_yaml文件的路径 |
-c | –config | 只可以指定为`local`或是`ali-oss`,分别表示读取本地的数据与读取阿里云的数据 |
-n | –num | 加载数据集的样本数量 |
-r | –random | 在加载数据集中的样本时是否随机选取样本,如果不指定的话就按顺序从开始选取样本 |
-v | –visualize | 是否将加载的数据进行可视化展示 |
-f | –field | 选择需要进行可视化的字段,如`-f bbox`表示可视化bbox,-f label`表示对label进行可视化等等,可以同时选择多个,如-f label bbox bool` |
