how do you visualize the npz files by nerfvis?

[Holmes-Alan]

I understand that you release the trained NeRF-SH models as well as converted plenoctrees. However, when I used your converted plenoctrees for 3D visualization like using "ship.npz" from your file as following,

import nerfvis
scene = nerfvis.Scene("My 3D model")
scene.export(dirname='checkpoints/ship', display=True,
tree_file='tree.npz',
url="100.80.243.129", port=80)

I cannot get a 3D view from my browser. It always show loading at 100% but it never visualize the view, like

I assume that the problem is from the plenoctree compression step but I still cannot get it resolved.
Could you please help me out? Thank you!
