Cannot re-open the scene reconstruct by app_opt enable

[chaoer]

Hi,

I try to reopen a scene, which reconstruct with app_opt enabled using the simple_viewer, and it failed with following error:

File "../gsplat/examples/simple_viewer.py", line 116, in main
    sh0.append(ckpt["sh0"])
KeyError: 'sh0'

I noticed that the sh0 and shN are replaced by features and colors when the app_opt is enabled. (in simple_trainer.py create_splats_with_optimizers).

So, what can i do to reopen this scene?
