Hi, this is strange. The training should done in less than 1 hour. Please refer to https://github.com/autonomousvision/mip-splatting/issues/54. Could you please check how many gaussians are used?
Many thanks for the rapid reply.
I'm training with mipnerf360, on flowers with factor = 8.
I followed the suggestions in #54 and remove selected_pts_mask = torch.logical_or(selected_pts_mask, selected_pts_mask_abs)
for the density setting, I set the threshold as 0.5: gaussians.densify_and_prune(opt.densify_grad_threshold, 0.5, scene.cameras_extent, size_threshold)
I check the Number of points at initialisation is 38347, at iteration 5100/30000, its 866647, 5200/30000 is 884200. Is that a normal setting?
Yet the code for nerf_synthetic works well, do you have any idea what's the potential issue?
Many thanks for the great work! I'm wondering how long does it take to train a single scene?
I'm training locally on a windows machine w. 4080s, cuda 12.4, the training on "flowers", the process slows down from 9%~10%:

Is it normal?
