How to prepare the data?

[Chang-Bin Zhang]

I noticed that there are some differences in data.
How can I prepare the data?

You don't really have to prepare anything per se. For VOC and ADE you can use Cermelli's script which are in the data folder. For Cityscapes I've simply download the link they gave me (you need to send some request to Cityscapes org), and unzip all compressed files.

Then you need to specify in command line, which dataset you want and what is the DATA_ROOT.

Hi, this is my 'data' folder
.
DATA_ROOT is 'data/'

[Arthur Douillard]

Your DATA_ROOT for, for example VOC, should contain the folders SegmentationClassAug, VOCdevkit, and list.

The 1st contain segmentation masks, the second the pixel images, and the third the train/val split.

Thank you very much! I have solved this problem!

Great! I'll to add more explanation in the readme if I can make it clearer.

Don't hesitate to open a new issue, if you have other problems :)
