output vector is all zeros of project_gaussians

[lixinhaiyk]

These input values are all correct, but the output vector is all zeros.Has anyone encountered this issue before?
the version is gsplat==0.1.2.1

        self.xys, self.depths, self.radii, self.conics, self.num_tiles_hit, self.cov3d__ = project_gaussians(  # type: ignore
            means_crop,
            scales_crop,
            1,
            quats_crop / quats_crop.norm(dim=-1, keepdim=True),
            viewmat.squeeze()[:3, :],
            projmat,
            camera.fx.item(),
            camera.fy.item(),
            cx,
            cy,
            H,
            W,
            #self.config.block_width,
            tile_bounds,
        )  # type: ignore

It seems like the original code is

self.xys, self.depths, self.radii, self.conics, _, self.num_tiles_hit, _ = project_gaussians(  # type: ignore
            means_crop,
            scales_crop,
            1,
            quats_crop / quats_crop.norm(dim=-1, keepdim=True),
            viewmat.squeeze()[:3, :],
            camera.fx.item(),
            camera.fy.item(),
            cx,
            cy,
            H,
            W,
            self.config.block_width,
        )  # type: ignore

And I found there misses a parameter projmat, how to calculate it?

Yes, but the interface for gsplat==0.1.2.1 version is like this. I had to adjust it to get it running.

I just run pip install gsplat==0.1.11 and the problem seems to be solved，you can give it a try.

pip install gsplat==0.1.11

It says that "nerfstudio 1.0.0 requires gsplat==0.1.2.1, but you have gsplat 0.1.11 which is incompatible." How did you get around this?

pip install gsplat==0.1.11

install nerfstudio=1.0.3andgsplat==0.1.11, and no need to modify the code after installation.

Sorry to keep bothering you, but I got this error "ImportError: DLL load failed while importing gsplat_cuda: The specified module could not bund." Did you get anything like this?
