t_starts getting empty #240

Open FlyCole opened 1 year ago

FlyCole commented 1 year ago

Hello,

I'm currently using your instant-ngp example (v0.5.3). However, I met a weird problem. During training, sometimes the training and also the testing goes well, but then suddenly n_rendering_samples becomes 0 and the rendered image becomes just black. I tried to debug a bit, seems the t_starts, t_ends, ray_indices become [ ] without any element inside the list.

May I ask do you maybe have some insight into it? Thank you!

Meet the same issue. When I try to expand aabb or scale down my poses, and then the program always stuck in _C.traverse_grids() this function. and GPU 100%. this function in grid.py->traverse_grids(). Can author help us, so much thanks.
