Seems that they changed the way they organize the dataset. I cannot use the preprocessing code for CityScapes either.

After modifying the code a little bit, I now have 1638 images as training split, 191 images as val split. Not sure if the author used the same setting.

What kind of error does it give you when you use the preprocessing code?

What I did to make the code works:

1. Remove the suffix "_sequence"
2. Swap the orders of "snippet_id" and "tgt_local_frame_id" and orders of "snippet_id" and "curr_local_frame_id" in is_valid_example() and load_image_sequence() in data/cityscapes/cityscapes_loader.py

Then I can get 1638 images as training split, 191 images as val split.

You need to download the package called leftImg8bit_sequence_trainvaltest.zip(324GB) so it contains video snippets. After preprocessing I had ~69K training snippets and ~7K validation snippets.
