update instructions to the latest gsplat

[czero69]

Hey, could we please update to the latest gsplat=1.0.0 ?

the instruction in readme is now: pip install git+https://github.com/yzslab/gsplat.git but this is installing 0.1.12 version of gsplat whether the latests are 1.0.0, could get from pip install git+https://github.com/nerfstudio-project/gsplat.git

Hi, only v0.1.12 is supported currently. I will upgrade to v1 when they have the next release later.

@yzslab There is a recent release (https://github.com/nerfstudio-project/gsplat/releases/tag/v1.3.0) which has some massive upgrades such as support for compression, orthographic projection.

I noticed that, but I am busy doing experiments, so maybe later.

@yzslab @czero69 @cs-mshah I tried to update gsplat rasterizer version but directly usage of rasterization is not possible. All gradients are attached in strategy part. So no way to directly use like in older versions.

Take a look this if you really need it: https://github.com/yzslab/gaussian-splatting-lightning/blob/gsplat_v1/internal/renderers/gsplat_v1_renderer.py

Hi, sorry for keeping everyone waiting.

I have added the v0 interfaces to the latest gsplat v1 so it can work on this repo now:

pip install git+https://github.com/yzslab/gsplat.git@v1-with_v0_interfaces

This just a workaround so v0 is still the recommended choice, unless you really need v1.

@yzslab Sorry to bother you again. I am trying to train appereance model with gsplat_v1 branch with gsplat-v1 version. I am getting this error. I replaced GSPlatRenderer with GSplatV1Renderer. Can you help to fix this issue?

  File "/home/hd/Desktop/python_workspace/gaussian-splatting-lightning/internal/gaussian_splatting.py", line 241, in forward
    return self.renderer.training_forward(
  File "/home/hd/Desktop/python_workspace/gaussian-splatting-lightning/internal/renderers/gsplat_appearance_embedding_renderer.py", line 164, in training_forward
    return self.renderer(
TypeError: 'GSplatV1Renderer' object is not callable

Thanks

I replaced GSPlatRenderer with GSplatV1Renderer. Can you help to fix this issue?

You need to invoke the instantiate() interface of the GSplatV1Renderer, and then assign its return value to self.renderer. It means that in GSplatAppearanceEmbeddingRenderer's setup(), there should be self.renderer = GSplatV1Renderer().instantiate().
