Hi! Thanks for providing 16*16 camera embedding in motion prediction task. But how can I get calibrations matrix of each camera?

``` def sample_ray(ori_rays_o, ori_rays_d, step_size, scene_center, scene_radius, bg_len, world_len, bda, **render_kwargs): rays_o = (ori_rays_o - scene_center) / scene_radius # normalization rays_d = ori_rays_d / ori_rays_d.norm(dim=-1, keepdim=True) N_inner = int(2 /...

Amazing work! But could you fix the bug in dataset download? The _url: https://huggingface.co/viewformer/ViewFormer-Occ_ can not be opened.

Hi, Are the results of 4D-Occ shown in Table 2 independently reproduced by your team?
