So sorry for the super late answer.

But if someone needs it in the future.
You need to prepare masks and metadata by running:

python main.py prepare_masks
python main.py prepare_metadata --train_data --valid_data

as explained in the REPRODUCE_RESULTS.

Once this is done you can run the pipeline.
