how to process dataset?

[XLechter]

The dataset structure should look like:
cityscapes/
gtFine/
train/
val/
test/
leftImg8bit/
train/
val/
test/
You should first download the gtFine and leftImg8bit from cityscapse website, and then change the root=youdir/cityscapes in configs/default.yaml.
Hope this helpful to you.
