Submission

Predict a class for every image of the split and submit to the CodaBench competition (link in the course slides).

One line per image, <image_path> <predicted_class_id>, with class_id in [0, 9999]:

val/image_000000.jpg 1234
val/image_000001.jpg 5678
...

Name the file val_team_XX.txt (Phase 1) or test_team_XX.txt (Phase 2), zip it, and upload the zip. Every image of the split must appear exactly once.

Validation and test labels are withheld. Do not label validation/test images by hand or train on them.
