Getting all gray images when training Plenoptic dataset with general MLP setting #22

Closed uchithaR closed 1 week ago

Hi, I was trying out both HexPlane and Hexplane_slim. However, the plenoptic dataset only works with Hexplane_slim. Please help me to resolve this issue.

my nv3d.yaml file looks like this.

systems: basedir: "./logs" vis_every: 5000

model: N_voxel_init: 262144 time_grid_init: 31 time_grid_final: 300 upsampling_type: aligned upsample_list: [70000, 140000, 210000] update_emptymask_list: [50000, 100000, 150000, 220000] fusion_one: "multiply" fusion_two: "multiply" density_n_comp: [12, 12, 12] app_n_comp: [24, 24, 24] fea2denseAct: softplus #relu app_view_pe: 2 app_fea_pe: 2

Hi. Can you try to change fusion_two from multiple to sum? If both of them are multiply, you may want to have a better initialization value for the plane to control the magnitude of valued.
