I substitute them with paths as follows:

: /home/jonsnow/svox2/opt/ckpt/my-first-exp/ckpt.npz : /home/jonsnow/svox2/datasets/my-dataset-folder I believe the dataset is used in the rendering process just to - understand where the "up" vector of the scene is, so to correctly render the target upstanding as it was captured, - for better side to side comparison in the test views generated
