non-zero size error

[uuu686]

hello, thank you for your work. And I want to ask a question.

when test after train,the error will happen:

vmin, vmax = mesh_coarse['v_pos'].amin(dim=0), mesh_coarse['v_pos'].amax(dim=0)
IndexError: amin(): Expected reduction dim 0 to have non-zero size

And I found that I must set the 'up_est_method' to 'ground' and set 'center_est_method' to 'point', or the error will happen.

I want to use the 'room' data provided by MipNeRF 360, and the result is bad.

Please tell me what should I do?
